I'm using bash when I'm logged in, but I really find it's memory
consumption a bit too much. I changed to /bin/sh for a while, but I
could not find any reasonable way of making my prompt something like:
hostname!user:/current/path$ ...
It seems that if I put in my .shrc the commands:
PS1="`hostname`!$LOGNAME:`pwd`\$ "
the prompt is fine, but when I change directories, the prompt stays
unchanged, and the new `current' directory is not there. This is
perfectly normal, since sh(1) expands `pwd` once when setting PS1.
Is my only option a shell function like?
cd () { chdir "$@" ; export PS1='blah blah'; }
I tried looking in sh(1) manpage for anything like an escape sequence
to put in the value of PS1, but I couldn't find anything helpful...
