You can check how long it has been since the last time the file was
modified.

The following script gets the current date and the modification date of
the file, both in the UNIX time (number of seconds since Jan 1, 1970),
then calculates the difference in hours and days.

#!/bin/sh
#
# Display the age of the file named on the command line.

# Get the current date in UNIX time.
currdateunix=`date +%s`

# Get the modification date of the file in human-readable format.!
filedate=`ls --full-time $1 | cut -c 48-62`

# Convert the human-readable file modification date to UNIX time.
filedateunix=`date -d "$filedate" +%s`

# Calculate the difference in seconds between the modification date and
# the current date.
fileageunix=$[$currdateunix-$filedateunix]

# Display the age in days and hours.
echo "$1 is $[$fileageunix/3600] hours or $[$fileageunix/86400] days old"

# End of script
