Comparing the file drop date with todays date
Daily one file will dropped into this directory.

Directory: /opt/app/jt/drop
File name: XXXX_<timestamp>.dat.gz

I need to write a script which checks whether the file is dropped daily or not.
Any idea in the script how can we compare timestamp of the file to today's date??

check if this is helpful to you:
Code:
today=`date '+%Y%m%d'`
ls -1 /opt/app/jt/drop/*.dat.gz | grep $today
echo $?
