crontab -e command not found

Dear All,
I have a new centos 5.5 machine. The problem when I type crontab -e it gives me -bash: crontab: command not found. How make my crontab work ? Thank you.

 

Are you logged in as root?

Does

Code:

/sbin/crontab -e

work?

 

Try:

which crontab

ps -ef | grep cron

If there is no output you can install 'crontabs' with:

yum install crontabs vixie-cron
