Assuming said command doesn't have such functionality 'at' would be the better tool anyway.

Cron would be useful if you want to regularly shutdown or reboot the machine on some definable interval without usually having to worry about it. If it's just a one time delayed shutdown, then yes, using the functionality built in to shutdown would be the better approach.

That's the information I'm trying to get from him (I think Long Wind is male, my apologies to you if you aren't). 'crontab -e' will create a crontab as the user, but crontabs created as a normal user shouldn't have the user field populated. 'crontab -l' will list the contents of the crontab created by 'crontab -e', so if the crontab was created this way (with a username), it will look fine but when cron tries to run the job it will look for a command that is the username with the rest of the line as arguments. If the intention is to run a cronjob as some system user the simplest method is to create a file in /etc/cron.d, which would require the user field to be populated.

Where did you create the file? Are you expecting the machine to shutdown when you invoke 'crontab cmd'?
