Directory changer for DOS and Unix. Another Norton Change Directory (NCD) clone with more features. Wcd is a program to change directory fast. It saves time typing at the keyboard. One needs to type only a part of a directory name and wcd will jump to it. Wcd has a fast selection method in case of multiple matches and allows aliasing and banning of directories. Wcd also includes a full-screen interactive directory browser with speed search. By default (if no wildcards are used) wcd searches for a directory with a name that begins with the typed name. For instance: wcd Desk will change to directory /home/waterlan/Desktop When there are multiple matches, wcd will present the user a list of all matches. The user can then make a selection with a few keystrokes (most of the times only one). Wcd fully supports wildcards, i.e. *, ? and [SET]. `*' matches any sequence of characters (zero or more) `?' matches any character [SET] matches any character in the specified set, [!SET] or [^SET] matches any character not in the speci­ fied set. A set is composed of characters or ranges; a range looks like ``character hyphen character'' (as in 0-9 or A-Z). [0-9a-zA-Z_] is the minimal set of characters allowed in the [..] pattern construct. Other characters are allowed (i.e. 8 bit characters) if your system will support them. To suppress the special syntactic significance of any of ``[]*?!^-\'', in- side or outside a [..] construct and match the character exactly, precede it with a ``\'' (backslash). Using wildcards makes powerful searching possible. For instance: wcd *top match any directory name that ends with "top". wcd *top* match any directory that has "top" in the name. wcd [a-c]* match any directory name that begins with "a", "b" or "c". It is also possible to give a part of a directory path. E.g.: wcd me/Desk wcd searches for directory that begins with "Desk" and which path matches *me/Desk* On DOS and Windows systems it does not matter if you use a slash (/) or a backslash (\) as directory-separator. It is allowed to type any kind of expression with slashes and wildcards. E.g.: wcd src*/*1?/a*2 If no wildcards are used and wcd finds a perfect match, wcd will ignore all wild matches by default. This behaviour can be changed with the -w option. It is also possible on DOS and Windows systems to change drive and directory in one go by preceding the directory name with the drive name. wcd d:games The interactive directory browser can be started by using option -g. wcd -g See option -g for more information. Wcd generates a treedata file were it searches the direc­ tory. On Unix systems wcd does add links to the treedata files while scanning the disk, but does not follow them. While following links wcd could end up scanning infinite loops, or scan very large portions of a network. On Unix systems a very handy option -u can be used to change to directories of other users. See option -u. Wcd can also change to directories that are not in the treedata file. E.g.: wcd .. If wcd found a match but cannot change to the directory it tries to remove it from the default treedata file. Not from the extra treedata file. Wcd keeps a directory stack which is stored on disk. The stack has a default size of 10 and is cyclic. See options -z, -, + and =. FILES wcd.exe The binary. Do not rename it to 'wcd' on Unix systems. On Unix systems the binary is always executed via a function or alias. default treedata file DOS: \treedata.wcd or %HOME%\treedata.wcd UNIX: $HOME/.treedata.wcd This is the default treedata file where wcd searches for matches. If it is not readable wcd will create a new one. extra treedata file DOS: \extra.wcd or %HOME%\extra.wcd UNIX: $HOME/.extra.wcd An optional extra treedata file. If it exists and is readable wcd will try to find matches in this file also. ban file DOS: \ban.wcd or %HOME%\ban.wcd UNIX: $HOME/.ban.wcd In this optional file wcd places banned paths. See option -b. Wildcards are supported. alias file DOS: \alias.wcd or %HOME%\alias.wcd UNIX: $HOME/.alias.wcd Optional file with wcd aliases. See option -l. stack file DOS: c:\stack.wcd or %HOME%\stack.wcd UNIX: $HOME/.stack.wcd In this file wcd stores it's stack. The drive-letter can be changed with the -d option. go-script DOS BASH: c:\wcd.go or %HOME%\wcd.go WIN32 CONSOLE: c:\wcdgo.bat or %HOME%\wcdgo.bat WIN32 ZSH: %HOME%\wcd.go UNIX: $HOME/bin/wcd.go This is the shell script which wcd.exe creates each time. It has to be executed via a function or an alias. The drive-letter can be changed with the -d option. For history reasons it is placed by default in ~/bin on Unix systems. The directory of this file can be changed with the option -G. relative treedata file DOS: \rtdata.wcd UNIX: /.rtdata.wcd Text file with relative paths from . See options +S, -n and +n. The win32 console version of wcd behaves as the DOS ver- sion. The Cygwin version of wcd behaves as the UNIX version. All .wcd files are ASCII text files. They can be edited with a text-editor. If the environment variable WCDHOME is set wcd will use WCDHOME instead of HOME. OPTIONS -s (re)Scan disk from your $HOME directory. This is recommended if you are on a large Unix server network with very much users. This is the default scanning mode. Wcd for DOS scans the cur- rent disk from root \ or from %HOME% if HOME is set. The existing default treedata file is over- written. -S Scan disk from a certain path. If you have a small Unix system like a PC with a few users you can scan the disk from /. The exist- ing default treedata file is overwritten. +S Scan disk from a certain path. Make relative tree- data file. Scan disk from path and place relative paths in a relative treedata file. This file is used by the -n and +n options of wcd. E.g. wcd -n src -a Add current path to default treedata file. Use this option to quickly add the current path to the default treedata file. Re-scanning the complete disk can take a long time in some cases. -aa Add current and all parent paths to default tree- data. -A Add directory tree from to default treedata. The directory tree starting from is appended to the default treedata file. Example: wcd -A . -e Add current path to extra treedata file. Use this option to quickly add the current path to the extra treedata file. -ee Add current and all parent paths to extra treedata file. -E Add directory tree from to Extra treedata file. The directory tree starting from is appended to the Extra treedata file -c direct CD mode By default wcd works as follows: 1. Try to find a match in the treedata file(s) 2. If no match, try to open the directory you typed. In direct CD mode wcd works in reversed order. 1. Try to open the directory you typed. 2. If not, try to find a match in the treedata file(s). -w Wild matching only. Treat all matches as wild matches. -b Ban current path. Wcd places the current path in the ban file. This means that wcd ignores all matches of this direc- tory and its subdirectories. The match is printed in unquiet operation. The ban file can be edited with a text editor. Use of wildcards is supported. Paths must be absolute (not relative). Banned paths are not excluded from scanning the disk. To do that use option -xf. -x Exclude from scanning. When this option is used wcd will exclude and all its subdirectories when wcd is scanning a disk. must be an absolute path. Option -x can be used multiple times. wcd -x -x -s Option -x must be used in front of any scan option (-s, -S, +S, -A, -E). On DOS/Windows systems one must specify the drive letter depending on if enviroment variable HOME or WCDHOME is set. If HOME or WCDHOME is set one needs to specify the drive letter. Example: wcd -x c:/temp -S c: Otherwise don't specify drive letter. wcd -x /temp -s -xf Exclude all paths listed in from scanning. When this option is used wcd will exclude all paths listed in and all their subdirectories when wcd is scanning a disk. The paths in must be absolute, one path per line. Wildcards are sup­ ported. Option -xf can be used multiple times. When one wants to exlude all banned paths from scanning one can do the following (example for wcd on unix): wcd -xf ~/.ban.wcd -s Option -xf must be used in front of any scan option -k Keep paths. Keep paths in treedata when wcd cannot change to them. The default behaviour of wcd is that it tries to remove paths from the treedata when wcd cannot change to them. With this option this behaviour is turned off. -l aLias current path. -q unQuiet operation. With this option wcd prints all the matches while wcd is scanning the treedata files. Also banned matches are printed. -Q Quieter operation. Printing of the final match is suppressed. -u Add default treedata file of other user, do not scan your own default treedata file (Unix only). Wcd now scans the ~/.treedata.wcd of another user It is assumed to be /home//.treedata.wcd The default treedata file is not scanned. +u Add default treedata file of other user (Unix only). -f Add another treedata file to be scanned, do not scan the default treedata file. +f Add another treedata file to be scanned. -n Add relative treedata file (Unix: /.rtdata.wcd, DOS: \rtdata.wcd), do not scan the default treedata file. If is a file, wcd will add instead of /.rtdata.wcd or \rtdata.wcd. See also option +S. Example: suppose another system has been NFS mounted to mount point /mnt/network wcd -n /mnt/network src Wcd now opens file /mnt/network/.rtdata.wcd The file contains the paths relative from that point. The relative treedata file should already have been created using the wcd +S option. +n Add another relative treedata file. See option -n. -i Ignore case. Dos and Windows versions of wcd ignore case by default. Unix versions regard case by default. +i Regard case. See also option -i. -m Make directory and add to treedata file. -M Make directory and add to extra treedata file. -r Remove directory and remove from treedata file. If the directory is empty, wcd will remove it, and try to remove it from the treedata file. -rmtree Recursively remove directory and remove from tree- data file. Wcd will remove the directory and all it's subdi- rectories and files, and remove the directories from the treedata file. -d Set drive for stack and go file (DOS only). The stack file and the go-script are by default stored on drive c: if environment variable HOME is not set. Use this option if drive C: is a read-only drive. This option must be used in front of the stack options -, + and =. -t Do not strip tmp mount dir /tmp_mnt (Unix only) Wcd strips by default /tmp_mnt/ from the match. Directory /tmp_mnt is used by the automounter. This behaviour can be turned off with the -t option. -v Print version info. -g Graphical interface (only in version with curses interface). Wcd starts a textual curses based `graphical' interface. The user can select a directory via a full screen interactive directory browser. It has a Vi(m) like navigation and search method. If no search string is given wcd presents the whole tree which is in the default treedata file and the extra treedata files. If a search string is given the match list is pre- sented as a graphical tree. -N Use numbers instead of letters. Wcd with a conio or curses based interface (see section INTERFACE) presents a match list default numbered with letters. When the -N option is used the match list is numbered with numbers. Regard- less of the -N option one can type a letter or num- bers to make a selection from the list of matches. -o Use stdin/stdout interface. When for some kind of reason the conio or curses interface of wcd doesn't work one can fall back to the stdin/stdout interface of wcd by using the -o option. -j just go mode In this mode wcd will not present a list when there is more than directory that matches the given directory. Wcd will just change to the first option. When wcd is invoked again with the same arguments it will change to the next option, and so on. Wcd will print the directory to go to to stdout. So a different installation method can be used. One could make the following function for bash or ksh: function wcd() { cd "`$HOME/bin/wcd.exe -j $*`" } On windows systems, if one is running 4NT shell, one could make the following alias: alias wcd `cd %@execstr[wcdwin32.exe -z 0 -j %1]` This method eliminates the need of the go- script, so one can use option -GN in combination with -j. -G Set directory path of go-script. -GN Don't create go-script. This option can be used in combination with the option -j if one doesn't want wcd to create a go- script. -z # Set maximum stack size. The default size of the stack is 10. Stack opera- tion can be turned off by setting the size to 0. This option must be used in front of any other stack option (-,+,=). Otherwise the size of the stack will be set back to the default 10. A correct command is: wcd -z 50 - The new stack size will be 50, wcd will go one directory back. A wrong command is: wcd - -z 50 Wcd goes one directory back, the stack gets the default size 10. '-z 50' is ignored. Add this option as the first option to your wcd alias or function. E.g. for the bash this would be: function wcd { wcd.exe -z 50 $* . $HOME/bin/wcd.go } -[#] Push dir [ # times ]. Go back a directory. 'wcd -' goes one directory back. To go more directories back add a number to it. E.g. wcd -3 The stack is cyclic. +[#] Pop dir [ # times ]. Go forward a directory. 'wcd +' goes one directory forward. To go more directories forward add a num ber to it. E.g. wcd +2 The stack is cyclic. = Show stack. Use this option if don't know anymore how many times to push or pop. The stack is printed and you can choose a number. The current place in the stack is marked with an asterisk '*'. INTERFACE Wcd has three different interfaces to choose from a list of matches. The interface can be chosen at compile time. The first interface uses plain stdin/stdout. A numbered list is printed in the terminal. The user has to choose from the list by typing a number followed by . This interface does not provide scroll back functionality in case of a long list. The scroll back capability of the terminal/console has to be used. It is very small and portable. The second interface is build with the conio library. It provides a build-in scroll back capability. The user is presented a list numbered with letters. Choosing from a list can be done by pressing just one letter. This inter- face is fast because it saves keystrokes. If possible the screen will be restored after exiting. One who prefers to type numbers can use the -N option. This interface is meant for DOS systems. The third interface is build with the curses library. It is similar to the curses interface with additional side- ways scrolling. The curses version of wcd has also an additional `graphi­ cal' interface. It lets the user select a directory via a full screen interactive directory browser. It has a Vi(m) like navigation and search method. It can be activated with option -g. This interface is portable to DOS, Windows and Unix. By using the -o option one can always fall back to the stdin/stdout interface. ENVIRONMENT Wcd uses environment variable HOME to determine where to store its files. See also section FILES. Environment variable WCDHOME overrides HOME. If both HOME and WCDHOME are set, WCDHOME will be used instead of HOME. For the Unix and Cygwin version it is required that HOME or WCDHOME is set. For the other versions of wcd the use of these variables is optional. If the environment variable TERMINFO is defined, wcd with ncurses interface checks for a local terminal defini- tion before checking in the standard place. This is useful if terminal definitions are not on a standard place. Often used standard places are /usr/lib/terminfo and /usr/share/terminfo. Wcd with PDCurses interface recognizes the environment variable PDC_RESTORE_SCREEN. If this environment variable is set, PDCurses will take a copy of the contents of the screen at the time that wcd is started; when wcd exits, the screen will be restored. One can set this variable e.g. in AUTOEXEC.BAT. Example: set PDC_RESTORE_SCREEN=1 For Cygwin this would be 'export PDC_RESTORE_SCREEN=1'. ====================================================================== = 2 DOS/Windows installation = ====================================================================== - dos 16 bit version: Make sure that wcd.exe is in your path. ...................................................................... - dos 32 bit version: Make sure that wcd.exe and cwsdpmi.exe are in your path. (requires 80386 CPU or higher) ...................................................................... - dos Bourne Again Shell (bash): (32 bit) 1) copy wcd.exe to your c:/bin directory. 2) Add the following function to your ~/_bashrc file. Notice that under Windows 95/NT the ~/.bashrc file overrides the ~/_bashrc file. In that case place the function in ~/.bashrc function wcd { c:/bin/wcd.exe $* . c:/wcd.go } Start a new bash Attention! wcd 2.1 and later writes the wcd.go file now always on drive C: unless other specified with the -d option. If you use environment variable HOME make a function like this: function wcd { c:/bin/wcd.exe $* . $HOME/wcd.go } ...................................................................... - Z shell (zsh) The dos bash version of wcd can also be used for the win32 port of zsh if it is used under Windows 95 or 98. It is required that environment variable HOME or WCDHOME is set. A function like the following must be defined. This can be done in $HOME/.zshenv function wcd { c:/bin/wcd.exe $* . $HOME/wcd.go } ...................................................................... - Long directory name support The 32 bit DOS versions for DOS supports long directory names in a Windows 95/98 Dos-box. Wcd makes use of DJGPP's LFN (long filename) API, which works under Windows 95 and 98. LFN support does not work if you started your PC in MS-DOS mode. LFN support can be controlled with the environment variable LFN. set LFN=y enables LFN support. set LFN=n disables LFN support. If variable LFN is not set, LFN is by default enabled. Notice that you need to have set LFN=y in your DJGPP.ENV file if you have the DJGPP compiler installed. ... Current DOS version of Wcd does not support LFN under Windows NT. An alpha version of an LFN driver for NT which enables long file name support for DJGPP programs, written by Andrew Crabtree, can be downloaded from Andrew's site (http://www.goof.com/pcg/data/djgpp/lfn0106.zip). If you need LFN support under Windows NT use the win32 console version of wcd. ...................................................................... - Using default options If you want to use some options by default use an alias or macro to do that. Smarter shells like 4DOS and NDOS are able to set aliases like this: alias wcd=wcd.exe -q In DOS BASH add the options in your function. In the MS-DOS COMMAND.COM shell you can use the 'doskey' command to define a macro. You could add the following line to you AUTOEXEC.BAT file: doskey wcd=wcd.exe -Q $* ...................................................................... - Use of environment variable HOME / WCDHOME The DOS versions of wcd can make use of environment variable HOME. (UNIX version always uses HOME.) set HOME=c:/home/waterlan If HOME is set, wcd will place all it's files (treedata.wcd, extra.wcd, alias.wcd, ban.wcd, wcd.go) in directory %HOME% . The behaviour of wcd is then equal to the UNIX version of wcd. Wcd will scan the disk default from %HOME%. Drives will not be automaticly scanned by changing to them. You need to tell wcd explicitly. E.g.: wcd -S c: -A d: -A e: Matching of directories is now global over all scanned drives. ... If HOME is set, DJGPP bash will read '_bashrc' from %HOME%. Your wcd function could now look like: function wcd { c:/bin/wcd.exe $* . $HOME/wcd.go } If the environment variable WCDHOME is set wcd will use WCDHOME instead of HOME. ...................................................................... - PDCurses interface The versions of wcd with pdcurses interface do by default not restore the screen after exiting. This can be controlled with the environment variable PDC_RESTORE_SCREEN. See the ENVIRONMENT section in the manual. ...................................................................... Adding extra directories: You can add an extra directory-list in the file \extra.wcd or %HOME%\extra.wcd Example: d:/games d:/games/invaders e:/project_a See also options -e and -E ====================================================================== = 3 Win32 console (Windows NT) installation = ====================================================================== Notice that under Windows NT console (MS-DOS prompt) a win32-program cannot change the current work directory (although a DOS-program can). That is why wcd generates a batch script (c:\wcdgo.bat or %HOME%\wcdgo.bat) which must be executed in the current shell. 1) Copy wcd.bat and wcdwin32.exe somewhere in PATH. 2) Edit wcd.bat depending if you use environment variable HOME or not. Suppose you installed wcd in c:\bin If you don't use environment variable HOME wcd.bat looks like: @echo off c:\bin\wcdwin32.exe %* c:\wcdgo.bat If you do use environment variable HOME wcd.bat looks like: @echo off c:\bin\wcdwin32.exe %* %HOME%\wcdgo.bat 3) To be sure that you execute the correct 'wcd.bat' you could optionally create a macro for wcd: doskey wcd=c:\bin\wcd.bat $* Notice that environment variable WCDHOME overrides HOME. ...................................................................... - Z shell (zsh) A win32 port of zsh has been made by Amol Deshpande (ftp://ftp.blarg.net/users/amol/zsh). It is required that environment variable HOME or WCDHOME is set. A function must be defined (e.g. in $HOME/.zshenv) like this: function wcd { c:/bin/wcdwin32.exe $* . $HOME/wcd.go } ...................................................................... - UNC support UNC stands for Universal Naming Convention. It is a Windows 9x/NT way of accessing network drives without using a drive letter. It's from Windows SMB LAN manager networking. A UNC path looks like: \\servername\sharename In Windows networking, you can map a drive letter to a UNC: net use G: \\gui_fileserv\apps Wcd does not support UNC notation. You need to map the UNC to a drive letter to access it via wcd. ====================================================================== = 4 Cygwin (Windows 9x / NT) installation = ====================================================================== 1) Make sure that environment variable HOME is set. Create a directory $HOME/bin 2) copy wcd.exe to your $HOME/bin directory. 3) Add the following function to your ~/.bashrc file. function wcd { $HOME/bin/wcd.exe $* . $HOME/bin/wcd.go } Start a new bash ...................................................................... The Cygwin version behaves exactly as the Unix version of wcd. o) regards case by default. - Use option -i to ignore case. o) does not use drive letters. - Use Cygwin's 'mount' command to access other drives than C: o) Uses the same filenames for treedata files etc. Use Cygwin's 'mount' command to access UNC named drives. ====================================================================== = 5 UNIX installation = ====================================================================== Notice that under Unix a program cannot change the current work directory. That is why wcd generates a shell script ($HOME/bin/wcd.go) which must be executed in the current shell via a function or an alias. The following examples show the installation on a system where you don't have root privileges. Read the manpage of the shell you are using on how to define a function or an alias. If the environment variable WCDHOME is set wcd will use WCDHOME instead of HOME. ...................................................................... Bourne-like shells: Korn Shell (ksh, pdksh), Bourne Again Shell (bash), Z shell (zsh), ash, ... : 1) copy wcd.exe to your $HOME/bin directory. 2) Add the following function to a startup file of your shell, e.g. in $HOME/.kshrc (ksh), $HOME/.bashrc (bash) or in $HOME/.zshenv (zsh). function wcd { $HOME/bin/wcd.exe $* . $HOME/bin/wcd.go } Start a new shell ...................................................................... C Shell (csh): 1) copy wcd.exe to your $HOME/bin directory. 2) Add the following alias to your $HOME/.cshrc file. alias wcd "$HOME/bin/wcd.exe \!* ; source $HOME/bin/wcd.go" Start a new C Shell ...................................................................... The executable can be shared among all users. The wcd.go file is personal: function wcd { /usr/local/bin/wcd.exe $* . $HOME/bin/wcd.go } ...................................................................... The first time wcd is used the program will scan your disk and build a .treedata.wcd file in your HOME-directory. The .treedata.wcd file can be updated by feeding the -s option. wcd.exe will generate each time a script wcd.go in your $HOME/bin directory which must be executed via the function. ...................................................................... Adding extra directories not on your own account: You can add an extra directory-list in the file $HOME/.extra.wcd Example: /home/piet/vhdl /home/piet/project_a/c/src /home/jan/perl See also options -e and -E ...................................................................... It is possible to turn off the automatic pathname expansion of the unix shell. In the C shell (csh) you can use 'set noglob' to turn it off, and 'unset noglob' to turn it on again. One could make the following wcd alias: alias wcd "set noglob; $HOME/bin/wcd.exe \!* ; unset noglob; source $HOME/bin/wcd.go" In the Korn Shell and the Bash the pathname expansion can be turned off and on with 'set -o noglob' and 'set +o noglob' (or 'set -f' and 'set +f'). But the function function wcd { set -o noglob /home/waterlan/bin/wcd.exe $* set +o noglob . $HOME/bin/wcd.go } does not have the desired effect. Can somebody help? ====================================================================== = 6 BUGS = ====================================================================== 1. Unix and DOS 32 bit version: - Strange behaviour when the argument has a wildcard and matches a file or directory in the current directory. This is the result of the pathname expansion of the shell. The work-around is to "double quote" the argument (in some shells). See also the section Unix installation. ...................................................................... If you think you found a bug do the following. First check that you have the latest version of WCD. The bug may already have been solved. If it has not been solved than send me an e-mail. Describe the bug and tell me what version of WCD you use and under what operating system. Addresses are at the end of this file. Also ideas to improve wcd are welcome. ====================================================================== = 7 Source code = ====================================================================== The source code for DOS 16 bit, win32 console, Cygwin and Unix is identical. The 16 bit DOS version and the win32 console version have been compiled with Borland C/C++ 4.02. Win32 versions can be compiled with Cygwin and Mingw32. Wcd for Unix compiles with gcc and with the native system C compilers such as HP-UX cc or SunOS cc. The 32 bit dos versions are compiled with DJGPP and have a different 'wcd.c' file and do not use DOSDIR. Wcd can optionally have a curse-based interface. Wcd compiles with curses, ncurses and pdcurses. The ncurses (new curses) library is a free software emulation of curses in System V Release 4.0, and more. It uses terminfo format, supports pads and color and multiple highlights and forms characters and function-key mapping, and has all the other SYSV-curses enhancements over BSD curses. The ncurses distribution is available via anonymous FTP at the GNU distribution site ftp://ftp.gnu.org/pub/gnu/ncurses. It is also available at ftp://ftp.clark.net/pub/dickey/ncurses. PDCurses is a port of System VR4 curses for multiple platforms. PDCurses has been ported to DOS, OS/2, X11, WIN32 and Flexos. A directory containing the port-specific source files exists for each of these platforms. Get it at http://www.lightlink.com/hessling/ DJGPP is a project to port the GNU C/C++ compiler to DOS. It includes a shell (bash) and many ported unix utilities.
