There are several ways to send mail but probably the easiest way is to use mail/mailx depending on your system.

simple example

Code:

echo "message from UNIX here"|mailx -s "your subject here" user@exchange.domain.com

thanks for your support.

Please provide details about how to setup a cran job?

Hi Thelak,

Look, first of all, we're talking about "cron" jobs, alright ! ...

Look, the tasks that you need to perform could be done inside a script, so you prepare a script with the tasks that you want and just set up the cron to execute them every hour, in this case .

1- Access your crontab with the following command
# crontab -e
(it is an empty file, you have to edit here what you need, the editor could be "vi")

2- Then add the following line.

0 * * * * /{path to your script}

---The 0 * * * * represents hourly, so the script will be processed every hour.

NOW, regarding the other points, look.

1- the mail!!!, use mailx ... I will show you how to do it soon
2- use find to "find" the large files, first, you have to define what is large for you.

eg. Find files greater then 5 megs (in bytes)

# find / -size +5000000c -exec ls -ltr {} \; --> this will show you the files, you have to refine this part to make it work with the file sizes that you really want.

OK... I will try to recreate what you are looking for.


Find the large files and compress them, let's say, files greater than 1GB ---- be carefull with this, you don't want to this with the OS files, etc.

Code:

find /tmp/files_to_shrink -size +1000000000c > /tmp/list_of_files

--- to see them
you can send this file to your email like this.

Code:

/tmp/list_of_files | mailx -s "files to compress" email@domain.com

If the file is ok, you can run a little script to read all that file, line per line, compress the files, then remove the files.

Hope that helps,

Marco,

thanks alot for your great support i will try this.
