is it possible to do a script that check a text file every five minutes, and if something is there, run a few commands?

thx

Yes.
Create your script.
And then using cron, you can schedule the script to run at specific times or intervals.

Sure. If you can write the script you want, you just need to make it executable and set it up as a cron job. Have a look at the crontab manual entry to find out how to execute a program every five minutes.

yes,
try to, use crontab (see man pages, or look in this forum, there should be some discusion about it)
or make in script infinitive loop with `sleep 300` command to wait 5minutes and do those commands You need.
There is also such thing as `FAM` it use fs notifications to track the creation of file (maybe also the changes of file, i dunno, i read today in mailing list about it )
Perl module using FAM can be found here http://search.cpan.org/author/JGLICK...lib/SGI/FAM.pm

hope smth. will help!

Yep, sure is.

You have to first create the script to check for the existence of the file, and run the commands. If you're not familliar with shell scripting, here's a basic template (bash):


#!/bin/sh
TESTFILE="/tmp/runit.dat"

if [ -f ${TESTFILE} ]; then
command1
command2
command3
fi


This script will look for the file called /tmp/runit.dat and will execute command1, command2, and command3 in succession if the file does exist.

The next thing you have to do is schedule the script to run every 5 minutes in cron (if you're unfamilliar with cron, man cron provides documentation.

Basically you'll want to add a line to your crontab file. Edit your crontab file (see manpage), and add the following line anywhere in the file:


5 * * * * /your/new/script/filename


where the /your/new/script/filename is, obviously, the location of the script file you created above, and the number 5 means "run every 5 minutes".

Install the crontab (again, see manpage) and you're good to go!

hope this helps.....
