For this, you need to keep record of the last time the check command ran.

This doesn't seem like an awk script. Just from shell is good enough, I think:

#!/bin/ksh
if [ $# -ne 1 ]
then
echo "Usage: $0 "
exit 1
fi
BASE=`basename "$1"`
STAMPFILE="/var/adm/stamps/${BASE}.stamp"

if [ -f $"{STAMPFILE}" ]
then
mv "${STAMPFILE}" "${STAMPFILE}.prev"
fi

ls -l "$1" >"${STAMPFILE}"

if [ -f "${STAMPFILE}.prev" ]
then
if cmp -s "${STAMPFILE}" "${STAMPFILE}.prev"
then
echo "Files are the same"
else
echo "File changed."
echo "Was:"
cat "${STAMPFILE}.prev"
echo "Is now:"
cat "${STAMPFILE}"
fi
else
echo "First run. Nothing to compare yet."
fi

Why using awk to find changed files, you can use find to find changed files within the last 24hours.

find /path/directory -mtime 1 >/tmp/tmp.lst
if [ `cat /tmp/tmp.lst | wc -l` -gt 0 ]
then
cat /tmp/tmp.lst | mailx -s "files found" account@domain.com
fi

Another approach:

Store the output of 'ls -l'.
Net time you run 'ls -l' again, and run a diff between the two listings.
This will only tell you 'something' has changed.

If you want to keep history, use rcs to store all (different) versions.
