Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Edit Crontab

this lets you edit a crontab file (which may be used as a backup as well) and insert this into your crontab. this way is especially handy, when multiple users are working on one account (e.g. root)

Alternatives

There are 5 alternatives - vote for the best!

Terminal - Alternatives
crontab -e

If you can do better, submit your command here.

What others think

The place of file .crontab is not defined.

"Each user can have their own crontab, and though these are files in /var, they are not intended to be edited directly." (man crontab)

crontab -e crontab -u user_name -e

It looks like what this command is doing is making a temporary file ~/.crontab and then loading it into the current user's crontab file. Sometimes I will do something like "vi ~/crontab.txt" and then when it looks nice I will do a "crontab ~/crontab.txt" to load it. This command looks like it simplifies this method a bit by putting both commands on the same line so as soon as you are done editing it, it loads the file.
