try..

Code:
 
awk -F"./hawk_" '{print $2}' filename

or

Code:
 
while read line ; do
echo ${line#*_}
done < filename

Another approach:
Code:
awk -F_ 'sub($1 FS,x)' file

Code:
awk -F"./hawk_" '{print $2}' filename

The above command is working perfectly.

Thank you so much for all of you for your prompt replies.
