Hi guys,

I currently use the below mwntioned grep statemen to get the timestamp of the last generated file in the directory.

(ls -ltr eCustomerCME* | grep ^- | tail -1 | awk ' { print $6,$7,$8 } ')

I need to modify this grep to search for files generated only within last 2 hrs. Can you pls suggest how to achieve that by modifying my grep or by some other method in my shell script. pls help me guys.. this is urgent.

thanks in advance

assume the time is now 09:46 Dec 28
12280746 is two hours earlier on Dec 28

 touch  -t 12280746 dummy
find .  -name 'eCustomerCME*' -newer dummy  -type f  -exec ls -ltr {} \; | tail -1 | awk ' { print $6,$7,$8 } ')
