Subject: Adding to the PATH but not if already in $PATH
Date: Sat, 26 Feb 2005 10:16:27 -0800 [thread overview]
Message-ID: <200502261016.28122.forestiero@qwest.net> (raw)
I want to prepend a directory to my PATH in my $HOME/.bashrc and export the
result. But I only want it to happen once: iow, if a directory I want
prepended is already in the PATH, do not prepend it again.
Something like:
if "/home/dw/bin" not in $PATH ; then
PATH=/home/dw:$PATH
export PATH
fi
The questions are: Is this the way one guards against multiple additions in
subshells? Is there a way to check for a substring?
