Hi ,
am getting output file, it sontains the below values.

./hawk_DOM1_FIRST_ENV
./hawk_DOM2_SECOND_ENV
./hawk_DOM3_THIRD_ENV

Now I need to grep the word "DOM1_FIRST_ENV","DOM2_SECOND_ENV"
like that.
I tired with cut -d "_". Its not working with any deleimiter.
Can you please help to resolve this. ??
Thanks in advance.

try..

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

or

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

Another approach:

awk -F_ 'sub($1 FS,x)' file
4 
awk -F"./hawk_" '{print $2}' filename

The above command is working perfectly.

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