What are cron jobs?

[jipman 0]

Cron jobs are something like a task scheduler, you can tell the server to run a script every once in a while.

Yes, there doesn't seem to be a whay to run a cron job from a windows environment. it seems that most cron jobs are php. does anyone know a way to run cron jobs from asp?

Cron jobs is a server side settings.You have to ask your server to give you permission to operate cron jobs.Cron jobs functions are easily available to non-windows servers.Most windows servers I had use before, do not support cron jobs.

Can we set-up cron to execute system commands? for example, i want to set-up a cron job to delete contents of a temporary directory?anyone?

Yes...

Cron jobs are something like a task scheduler, you can tell the server to run a script every once in a while.

so your script would be somthing like

#!/bin/bash#uncomment one of the following.#to delete a set directoryrm /path/to/temp/directory/* -R#to delete a tempory directory given in parameter 1#rm $1 -R

i know you are a windows user, and thats a nix script, but this server is running on a nix system.
for a windows system, replace "#!/bin/bash" with "@echo off" and "rm" with "del"

Slight improvision on the script to skip prompting in case it's enabled, since cronjobs can't interact:

#!/bin/bashrm -fR /path/to/temp/directory/*

You can set up cron jobs from your cpanel. I think it's under the Advanced Tools section. From there, you can enter the script to be run, then set the schedule, like once every 15 minutes for every day of the year, or once every day, or once every month, so on.

Can anyone just show an example of a script for both php and perl and guide us, how it is supposed to be entered in the Cron job thing in cpanel... I am also quite new to this thing..

here's a php code that will recursively delete all the files in a directory. To call this from a cron job, make the cron job run 'GET http://forums.xisto.com/no_longer_exists/ > /dev/null'. If you write a script that outputs some stuff (such as a script i wrote that synchronizes my site on Xisto with the backup site on another host), make the cron job run 'GET http://forums.xisto.com/no_longer_exists/ > /home/yourusername/public_html/results.htm'. Then, whenever it runs, it will save the results into http://forums.xisto.com/no_longer_exists/

<?phpfunction deldir($dir){ $current_dir = opendir($dir); while($entryname = readdir($current_dir)){    if(is_dir("$dir/$entryname") and ($entryname != "." and $entryname!="..")){       deldir("${dir}/${entryname}");    }elseif($entryname != "." and $entryname!=".."){       unlink("${dir}/${entryname}");    } } closedir($current_dir); rmdir(${dir});}deldir("/path/to/temp/directory/");echo "Deletion complete";?>
