Ultra shortcut for ssh root@

When you have to manage lot of servers, it's boring to type ssh root@myhost for each connection. Now you can type juste "s someting" and you are connected. You can too add bash_completion script to complet with tab the name of your servers. This will be the next tips from me ;) Show Sample Output

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

ssh X tunneling over multiple ssh hosts (through ssh proxy)

Simply makes it possible to launch any X application residing on sshhost through sshproxy and display it on your screen where ever you are.

Look for English words in /dev/urandom

Little faster alternative.

Create tar over SSH

Really useful when out of space in your current machine. You can ran this also with cat for example: $ tar zcvf - /folder/ | ssh root@192.168.0.1 "cat > /dest/folder/file.tar.gz" Or even run other command's: $ tcpdump | ssh root@10.0.0.1 "cat > /tmp/tcpdump.log"

Matrix Style

Unlike other alternatives, this command only relies on bash builtins and should also work on windows platforms with the bash executable. Sparseness corresponds to the number 128 and can be adjusted. To print all possible digits instead of only 0 and 1 replace RANDOM%2 by RANDOM%10 or RANDOM%16 to add letters [A-F].

Performance tip: compress /usr/

Periodically run the one-liner above if/when there are significant changes to the files in /usr/ = Before rebooting, add following to /etc/fstab : = $ /squashed/usr/usr.sfs /squashed/usr/ro squashfs loop,ro 0 0 $ usr /usr aufs udba=reval,br:/squashed/usr/rw:/squashed/usr/ro 0 0 No need to delete original /usr/ ! (unless you don't care about recovery). Also AuFS does not work with XFS

List all TCP opened ports on localhost in LISTEN mode

Alternative of OJM snippet : This one show the IP too, where ports bind. It's very important, because if there's only 127.0.0.1 instead of 0.0.0.0, connections from internet are rejected.

Print your cpu intel architecture family

faster version of ls *

I know its not much but is very useful in time consuming scripts (cron, rc.d, etc).

Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
