Is it possible to make echo " " a part of the unix prompt? My objective is to print a blank line before a prompt to improve clarity of the output from the previous unix command. The example follows: % % ls <output of "ls" command> % <blank line> % <now cursor is here> Will appreciate the response. Thanks! -- Ashok

The example follows: Your example suggests that you are using the C Shell (csh). Here is a way to set your prompt appropriately, first for the C Shell: set prompt="\ $USER:\!> " This will generate a prompt that begins with a blank line (as you asked for) and then prints the user's login name and the csh history number followed by a "less-than" sign. Note that the newline which is to be part of the prompt needs to be quoted with a backslash in the C Shell. All of this should go into your .login file if you want it only in your login shell, or in .cshrc if you want it in subshells as well. Here is an example for the Bourne Shell, which needs to go into your .profile: PS1=" $USER> " ; export PS1 This will generate a similar prompt to the above; if you do this on System V Release 2 (and maybe earlier) substitute "$LOGNAME" for "$USER". Of course, being Bourne Shell, it has no history number, and note that you do not have to quote the newline. The "export" statement ensures that you will get this same prompt in sub-shells, such as those spawned from within vi. If you have the Korn Shell, use the Bourne example, but make that "$USER:!> " instead -- the Korn Shell has history, and does not want the exclamation point escaped. Of course some people don't want their login name in their prompt, but instead the current directory -- this has been discussed endlessly a few months ago, and I am not going to re-start this discussion. -- Wolf N.

If you're using the real shell, then you can do PS1=`promptprog` where promptprog is a program that generates the new prompt. For example PS1=`cat << END_CAT $ $ END_CAT` Will double up dollar sign prompts. -Ron

The solution for about half the problems with the C shell is the same: Use more \ characters. You have to write alias cd 'cd \!* ; set ... \\ ... ' so that the alias itself has one \ in it. Some years ago, Fred Blonder and I were experimenting with working- directory prompts. The regular sorts of wd prompts were not hard, but we wanted to get `~' compression, so that one would see, e.g., [~] ==> cd /tmp [/tmp] ==> cd [~] ==> cd foo/bar [~/foo/bar] ==> cd baz [~/foo/bar/baz] ==> Unfortunately, csh insisted on expanding the `~' whenever we ran the output of `dirs' through awk to get the first string. Quoting helped: here is what we came up with (his version): alias set_prompt 'set prompt = '"'"'['"'"'"`dirs|awk '"'"'{print "\$1"}'"'"'`"'"'"'] ==> '"'"'' alias cd '\!:0-$; set_prompt' alias pushd '\!:0-$; set_prompt' alias popd '\!:0-$; set_prompt' set_prompt After some thought, I reduced this (after changing the style) to alias set_prompt 'set prompt="[\\!] `dirs|awk '\''{print "\$1"}'\''` "' alias cd 'cd \!*; set_prompt' alias pushd 'pushd \!*; set_prompt' alias popd 'popd \!*; set_prompt' set_prompt Of course, for faster operation, one can write set prompt=(`dirs`) but again csh insists on expanding `~'.... -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7163) Domain: chris@mimsy.umd.edu Path: uunet!mimsy!chris

Sorry, I've tried to RTFM, but I can't find 'alias' in >the reference manual my company has provided me. 1. ALIAS is explained (not as well as it could be) in the manual entry for CSH, it does not have an entry of its own. 2. No, csh does not like a newline (even disguised, escaped or quoted) in an alias definition. Try the following: File ~/.setprompt: set prompt="\ =5h`pwd`=5l\ (\!) " Alias line in file ~/.cshrc: (If it is in .login, effective only for login shell; if in .cshrc, effective for sub-shells as well) alias cd 'cd \!* ; source ~/.setprompt' This method effectively REMOVES the newline from the alias definition. -- Wolf N.

Notice: the newline and the second ! have to be escaped twice, once on setting
the alias and once on executing it.
BTW, it's a nice prompt indeed.
