But. .... > http://www.faqs.org/docs/Linux-HOWTO/Bash-Prompt-HOWTO.html Did this URL move/break? Anyhow since it looks broken at this moment. Two quick reminders. In the .bash-* files remember to verify that this is an interactive tty (pseudo terminal session). Many scripts, cronjobs, remote user, ssh user stuff will BREAK if bash is noisy when it should be quiet. Also test the $TERM environment variable and verify that this is a terminal that supports the magic you want. Have a default that makes sense... there are more than 1300 terminals described in the termcap data base you will not get them all so focus on the one or two you care about. Since this is an international list I should add that language and character sets can be important. If things look broken and you get stuck language and character variables too. Take /etc/bashrc as a starting place. Note that two things are checked... Interactive and $TERM=xterm. If users are at the end of a wyse50, vt100 or some other terminal/ emulation recheck this stuff. ================ snip ======================= # are we an interactive shell? if [ "$PS1" ]; then case $TERM in xterm*) if [ -e /etc/sysconfig/bash-prompt-xterm ]; then PROMPT_COMMAND=/etc/sysconfig/bash-prompt-xterm else PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/#$HOME/~}\007"' fi ================ snip ======================= Other shells (ksh, csh, tcsh) test for an interactive session differently. Note that csh and tcsh may want $term not $TERM. The escape sequences are specific to the terminal program, RTFM. Note the subtle change from $ to # as a user switches from a normal user to root (UID=0). Keep this small change intact. -- T o m M i t c h e l l /dev/null the ultimate in secure storage.
