how can i check if unix group exists 1

[philipose]

Hi,
I was using a branch logic in a shell script. If a particular Unix Group exists then do this else do something else.

Is there a way for me to check if a Unix group exists or not ?

Thanks

sth like this?

[tt]lsgroup -a id ${GROUP} 2>/dev/null && echo group ${GROUP} exists

lsgroup -a id ${GROUP} 2>/dev/null || echo group ${GROUP} does not exist

if lsgroup -a id ${GROUP} 2>/dev/null
then
echo group ${GROUP} exists
else
echo group ${GROUP} does not exist
fi[/tt]

Here is something a little more generic:

#!/bin/ksh

mygroup=xsys
myb=1
while IFS=":" read GROUP other
do
if [ $GROUP = $mygroup ]
then
myb=0
break
fi
done < /etc/group && (( $myb == 0 )) && echo "$mygroup exists"

Well, this IS an AIX forum so I gave an AIX answer... ;-)
