You could use something like

Code:

/bin/df -h |  /bin/mail -s "diskusage" you@you.com

Well what do you want your cron to do exactly?

Send an email? Write a log file? Etc...
if so, write a script which does what you want, and them put this script in your crontab

to add a cron just type

Code:

crontab -e

the diskspace is shared between peers.
I use du -h . to check my disk usage.

to be more specific, I want to have a cron job which will send me my project directory disk usage and send me a mail everyday in order for me to monitor it.
I need this because my simulation results will be stopped if hitting my disk quota / limit.

crontab -e
du -ah /diskpath/ | mail -s "diskusage" you@mail.com

crontab: installing new crontab
"/tmp/crontab.XXXX1osPQ8":1: bad minute
errors in crontab file, can't install.

You need to specify the time you want to run the crontab

If you've got quotas enabled, you could use http://linux.die.net/man/1/quota

Yes, create the cron as a user.
