Check for a pattern
Hi,

I have a script where I supply a parameter externally. Now when the script picks up the parameter, I want to verify if that parameter has a pattern such as "tag" in it.

I know that after reading the param the script can push it to a file and grep for the pattern, but I am looking for a more straight forward way.

Thanks
Sumeet

Code:
echo "Enter pattern\c"
read pattern
echo "$pattern" | grep -q 'tag' 
if [[ $? -eq 0 ]] ; then
   echo "good"
else
   echo "bad"
fi
