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

Tweak system files without invoking a root shell

Terminal - Tweak system files without invoking a root shell
echo "Whatever you need" | sudo tee [-a] /etc/system-file.cfg

Functions: echo sudo tee
Tweak system files without invoking a root shell

only for sudo-style systems.

Use this construct instead of I/O re-directors ``>'' or ``>>'' because

sudo only elevates the commands and *not* the re-directors.

***warning: remember that the `tee` command will clobber

file contents unless it is given the ``-a'' argument

Also, for extra security, the "left" command is still run unprivileged.


There are 2 alternatives - vote for the best!

sudo vim /etc/system-file.cfg

[quote]sudo vim /etc/system-file.cfg[/quote]

Yes, of course, but if all you need to do is replace the contents of a file with a one-liner,

the pipe is quicker - esp. when remotely managing a server.

If you need to type the full path of some file into a config file,

the pipe is quicker **and more accurate**

such as:

ls /var/log/samba/log.winbindd | sudo tee -a /etc/some-file.cfg sudo vi /etc/some-file.cfg

... you will know if your path and file are correct before

even vim-ing the config file.
