Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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.

Alternatives

There are 35 alternatives - vote for the best!

[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.
