How's about this for starters?

Save the script to file name of your choosing, such as "findfile.sh". And then make it executable to run it.

Code:

chmod +x findfile.sh
./findfile.sh

Code:

#!/bin/sh

# Inclusive time to search.
START=`date "+%Y%m%d0800.00"`
END=`date "+%Y%m%d1700.00"`
# Directory to search.
SEARCH="/"
# Username of files.
USER="samba"
# Temporary place to put scratch files.
TMPDIR="/tmp"

# Scratch files.
touch -t $START $TMPDIR/START
touch -t $END $TMPDIR/END

# Find the modified files.
find $SEARCH -type f -user $USER -cnewer $TMPDIR/START ! -cnewer $TMPDIR/END -exec ls {} 2> /dev/null \;

# Cleanup scratch files.
rm $TMPDIR/START
rm $TMPDIR/END

First of all, you can't tell who modified the file. You can only tell when it was last modified. Second, I'm a little puzzled by your 8 to 5. Wouldn't you want anything that had been modified since your last backup? If someone came in early or stayed late and modified files, then . . .

Anyway, check the man page for find. The search `find / -mmin -480` will find all files that were modified in the last 8 hours. Run that search at 5pm, and you have what you want.

Hi all, thanks for all your kind replies anyway, for now i just used find
command combine with rsync maybe something like this:

Code:

find /home/* -type f -mtime 0 -exec rsync -avz {} /destination \;

but i have a question again can i use some option on rsync maybe include files or exclude(to block *.mp3 files when backup process) cause i had try
something like this:

Code:

find /home/* -type f -mtime 0 >> find.txt

from that find.txt files it's contains full path directory files and i just want to try to use rsync for backup using that find.txt file so rsync just backup files with the directory on based on that find.txt files, here i post some of that files:

Code:

/home/warehouse01/Documents/Warehouse/stocks.xls

Need advise please and thank you.
