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.

In my work environment, we log onto the servers as our user ('user', in the sample ouput), and 'sudo su - root' to other accounts. This trick allows us to return the account name we logged in as -- and not the account name we currently are ('root', in this example).

Using this trick, you can build other commands:

Set your CVSROOT env variable to your account name:

CVSROOT=$(who am i | awk '{print $1}')@cvs.server.example.com:/cvsroot

SCP a file to another server:

scp file.txt $(who am i | awk '{print $1}')@some.other.server.com:.

This works out great in my environment, as we can include this in our documentation and make the comands more easy to copy/paste for different users, and not have to set all sorts of variables, or modify the docs for each user.

whoami gives you the name of the user you currently are, not the user you logged on originally as.

who gives you a listing of every single person logged onto the server.

who am i gives you the name of the user you logged on as, and not who you changed to with su.

Look at the following scenario:

whoami

user

su -

# whoami

root

# who am i

user pts/51 2009-02-13 10:24 (:0.0)

whoami != who am i

Why don't people search, to see if the command already exists?
