- TCL SHELL
-
- The basic idea of the Tcl Shell is to provide an interactive way to access
- TCL, it is *NOT* intended to serve as a pseudo-unix-shell. However, I don't
- use MPW or AU/X, and therefore I implemented a few very useful unix shell
- functions.
-
- All pathnames must be mac pathnames; relative pathnames start
- with colons, absolute pathnames don't. For instance, ':file1' specifies a
- file named 'file1' in the current directory. '::file2' specfies a file in
- the parent directory, and ':::file3' is a file in the parent's parent's
- directory. Additionally, hitting the tab key w/ a partial pathname invokes
- a filename-completion function that tries to fill in the rest of the
- characters of the name.
-
- The supported functions are all valid Tcl commands and the following:
-
- cat <file>... Dump contents of files into shell window.
-
- cd <relative or absolute pathname>
- Change directory. If called w/ no arguments, go to home directory if no
- arguments.
- cp <file1> <file2>
- or
- cp <file1> .... <destDir>
- Basic unix functionality, recursive.
-
- dirs - show current directory stack. See 'pushd' and 'popd'.
-
- grep <pat> <file>...
- Grep, reasonably slow.
-
- mkdir <dirname> - make a directory (folder)
-
- ls [-F|l] [<file>]...
- Two, mutually exclusive flags. '-F' just gives the normal display, with
- a '*' behind applications and a '/' behind directories (folders). '-l'
- presents a long listing, including sizes of both forks, creator, file
- type, and last modification time. 'procs.tcl' includes functions 'l' and
- 'll' which serve as my Unix aliases to 'ls -F' and 'ls -l'.
-
- mv <file1> <file2>
- or
- mv <file1> .... <destDir>
- Moves a file, potentially across volume boundaries. Recursive.
-
- popd - Pop top dir off dir stack and 'cd' to it.
-
- pushd [<dir>] - If 'dir' specified, push current folder into directory
- stack and 'cd' to dir. Otherwise, swap current dir w/ top of dir stack.
-
- ps
- Prints a list of active applications.
-
- rm [-r] <file>...
- Removes files and empty directories. "-r" allows recursive removal, but
- DON'T BLAME ME IF YOU DELETE YOUR ENTIRE DRIVE!
-
- rmdir <dirname> - remove a directory (folder)
-
- setCreator <creator> <files> - Changes the creator of given files, which can
- be glob expressions.
-
- setType <type> <files> - Changes the type of given files, which can
- be glob expressions.
-
- wc <file>...
- 'wc' primitive from unix, counts lines, words, characters.
-
-
- The file ":Tcl:SystemCode:shell.tcl" contains Tcl code implementing the
- shell interface. You can change this to suit your tastes. One recent
- goody is that you can re-execute previous commands merely by moving the
- cursor to the line and hitting the return key. If there is no '>'
- character on the line when you hit a carriage return, the return is an
- ordinary new line.
-
- A primitive history mechanism can be used to move up and down the last 20
- commands by using control-uparrow and control-downarrow at a prompt.
