This shows how to check if a file is older than a given date using Bash. I use this to test the age of my server backup log. If the log is more than a day old then I send an alert.
MAXAGE=`expr 60 \* 60 \* 24` # seconds in a day
# file age in seconds = current_time - file_modification_time.
FILEAGE=$(($(date +%s) - $(stat -c '%Y' "$FILE")))
test $FILEAGE -lt $MAXAGE && {
echo "$FILE is less than $MAXAGE seconds old."
}
