I have list file,I want to now if 1 file on a directory was change size or date time, I get the email for this case. If the file not modified the date time or size, email not come.

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.
