Print a file's last modified date in Bash

Isn't the 'date' command much simpler? No need for awk, stat, etc.

date -r <filename>

Also, consider looking at the man page for date formatting; for example with common date and time format:

date -r <filename> "+%m-%d-%Y %H:%M:%S"

You can use the stat command

stat -c %y "$entry"

More info

%y   time of last modification, human-readable

Best is

date -r filename +"%Y-%m-%d %H:%M:%S"
