I have a precmd() that I would like to augment to include source
control freeze info (we use clearcase, a freeze will change the way
files are represented).
precmd ()
{
....
if [[ $CLEARCASE_ROOT != "" ]]; then
RPROMPT=${RPROMPT:s/"%S f %s "//}
cleartool catcs | grep time > /dev/null
if [[ $? == 0 ]]; then
RPROMPT="%S f %s %$RPROMPT"
fi
fi
}
Basically the "cleartool catcs" command is required, if its output
contain 'time', then there is a freeze condition which I will modify
the RPROMPT to include an indicator.
However, this still added 2 more forks per command and the response is
not that desirable. Any way to speed this up, for example, is there
a way in zsh to replace the 'grep' above?
Thanks in advance.
