Hello lkeswar,

Please use code tags for commands/codes used in your posts as per forum rules. Following may help you in same.

i-
Code:
echo "20140412-s1-Potopolive_promos_20140412" | awk '{sub(/.*-/,X,$0);sub(/_.*/,X,$0);print}'

ii-
Code:
A="20140412-s1-Potopolive_promos_20140412"
B=`echo ${A##*-}`
echo ${B%%_*}

Output will be same in both the cases, hope this helps.


Thanks,
R. Singh

Note: instead of B=`echo ${A##*-}` one could use: B=${A##*-}

Hello Mannu2525,

Your code can be written as follows without using 2 times awk.
Code:
echo "20140412-s1-Potopolive_promos_20140412" | awk -F"-|_" '{print $3}'

Thanks,
R. Singh
