Thanks for the report. However bash is not right component, /etc/bashrc is part of setup package. *** This bug has been marked as a duplicate of bug 620408 *** |
Description of problem: The default PROMPT_COMMAND values set in /etc/bashrc interpret backslash escapes in $USER, $HOSTNAME and $PWD. This causes junk to be printed before the prompt if certain escape sequences are encountered, when any sequences should be printed literally. Version-Release number of selected component (if applicable): /etc/bashrc distributed with Bash in RHEL4.8 (3.00.15), RHEL5.5 (3.2.25) and RHEL6.0 (4.1.2). How reproducible: Always. Steps to Reproduce: $ cp /etc/skel/.bashrc ~ $ bash -il $ mkdir 'foo\abar' $ cd foo\\abar Examine prompt, 'bar' appears at the beginning. Or log on with a username containing an escape code (DOMAIN\alex) and examine prompt. Actual results: bar[alex@server foo\abar]$ Expected results: [alex@server foo\abar]$ Additional info: Fixed versions: xterm: PROMPT_COMMAND='echo -ne "\033]0;" ; echo -nE "${USER}@${HOSTNAME%%.*}:${PWD/#$HOME/~}" ; echo -ne "\007"' screen: PROMPT_COMMAND='echo -ne "\033_" ; echo -nE "${USER}@${HOSTNAME%%.*}:${PWD/#$HOME/~}" ; echo -ne "\033\\"'
