Hi, you are using wild cards (*) as in a globbing situation, whereas grep uses regular expressions so the equivalent would be ".*nitin.*" . With grep this makes little sense however.

If you are looking for the word nitin, you could use this:

grep -w nitin "$FILE"

or for words that contain nitin:

grep nitin "$FILE"

additionally you can use -q to silence grep, so you could do something like this:

if grep -q nitin "$FILE"
then
   echo 'Word found!'
else
   echo 'Word NOT found!'
fi

can you please tell me the case when i have to search nitin and there are entry in file like delhiNitin_Unix then how to match nitin here in same situation as explained above just .

what we need to change in below pattern:
grep -w nitin "$FILE"

I gather you do not require a word match, so we do not need -w and we need -i to ignore upper and lower case distinction, so I'd say:

grep -i nitin "$FILE"
