A few days ago, I asked a couple of questions (unfortunately I deleted the original file so I can't quote myself exactly. > In view-mode, ocasionally it sets the goal-column to zero.

By the way, I am running Emacs 18.55 on a Sun 4 with SunOS 4.0.3. > Finally, in *shell*, if I type 'cd a' it automatically sets the default > path to './a' but if I type a (alias a cd a) it leaves the default > path set to '.'.

There is a way to alias the cd command. Just add the command in .emacs (setq shell-cd-regexp "cd\\|sd") or something like that. Then, any time you type 'cd' or 'sd', it will set the default path. The problem is, it expects the path to be passed as a parameter IN THE SAME LINE. So if you have sd aliased to 'cd foo' for example, typing 'sd' in the *shell* will put you in the foo directory but will set your default path to ~/ since you didn't put a path in the line. Basically, the only thing this is good for is to alias the basic 'cd' command. Also, the alias can be at most 3 letters long since shell.el checks over 3 spaces in the line to see what the new path is. So, if you put in your .emacs file (setq shell-cd-regexp "cd\\|longcd") and had longcd aliased to cd and then typed 'longcd foo' in the *shell*, it would put you in the foo directory but would leave your path unchanged since you don't have a path "gcd foo" in your directory. Anyway, as far as I can tell, the only way I'm going to be able to make this work is to rewrite the shell.el command where this happens and instead of checking for arguments only on the command line, it will check for the arguments in the .chsrc file. I think I will eventually get around to doing it, but it is low priority right now. Thanks for all you help. S. Beck sull@biocat.chem.usu.edu slz7p@cc.usu.edu (slz7p@usu.bitnet)
