Neat ksh prompt
Posted Fri, 01 Aug 2003
My prompt is something in the form of:
This will let you use pwd and substitute ~ for your home directory. (pdksh currently doesn't support something like this, so the hack was needed)
Note the
hostname(/path/to/pwd) [###] >Unless the previous command that was executed returned an exit code other than 0, in which case it will display the exit code just before the > as !#! where # is the exit code.
from my .profile
[ -w "/" ] && Z="#" || Z=">"
EXITCODE='$(A=$? && [ $A -ne 0 ] && echo "!!${A}!! ")'
PS1='$HOST($(/bin/pwd | sed -Ee "s,(/usr)?$HOME,~,")) [!] '$EXITCODE'$Z '
This will let you use pwd and substitute ~ for your home directory. (pdksh currently doesn't support something like this, so the hack was needed)
That's it, here's an example of what it'll look like:
nightfall(~) [471] > nightfall(~) [471] > echo "hi there" hi there nightfall(~) [472] > ls -asoijo23i5j23 ls: illegal option -- j usage: ls [-ABCFGHLPRTWabcdfghiklnoqrstu1] [file ...] nightfall(~) [473] !1! > thisisnotacommand ksh: thisisnotacommand: not found nightfall(~) [474] !127! > cd bin nightfall(~/bin) [475] > cd /nope ksh: cd: /nope - No such file or directory nightfall(~/bin) [476] !1! > cd /usr/local/ nightfall(/usr/local) [477] >
Note the
!1! and !127!. These are the exit codes of the previous commands.
