Hi,
I'm currently writing an install script for an application, and my already limited Bash skills are a bit rusty.
I want to check if a group exists, and if it doesn't, then create it.
Only thing I found is:
if [ grep medintux /etc/group ]; then continue else groupadd medintux fi
Apparently I can't seem to "negate" the test, e. g. something like
if !(grep medintux /etc/group)
Any suggestions for the correct syntax here ?
Thanks,
Niki
Why don't you use groupadd -f ? It will not override the group if it already exists, and shortens the code :)
