Description Martin Sandiford 2002-04-21 06:21:56 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020311

Description of problem:
/etc/bashrc could set PROMPT_COMMAND to "source
/etc/sysconfig/bash-prompt-xterm" instead of executing directly.

This would prevent an additional shell being run for trivial shell scripts (eg
echo commands).  Scripts that required a separate shell execution could
trivially spawn a new shell in the script.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
This is a optimisation issue, rather than a bug per se.  The system is currently
performing as expected.



Additional info:

Simple change to /etc/bashrc (hence the setup package) at line 28 for setup-2.5.7-1:

From:
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-xterm

To:
PROMPT_COMMAND="source /etc/sysconfig/bash-prompt-xterm"

Hm, while this is an optimization, this would break making that an
executable (dunno why you'd do that, but...)
