Connect to irssi over ssh

This will launch and irssi session on your server. If it's not running, it will create the session. If it's running it'll connect to it and destroy any other connections. If compositing is available, the rxvt window will have transparency added. This window will also open maximized. Anything else this does should be easily figured out in the man pages.

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.

Preserve colors when piping tree to less

Find only *.doc and *xls files on Windows partition

When using regex - there is no need to use -o and 2nd regex.

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"

Recall last argument of previous command

!$ recalls the last argument of the previous command. This is very useful when you have to operate several operations on the same file for example.

Clear your history saved into .bash_history file!

Note the space before the command; that prevents your history eliminating command from being recorded. ' history -c && rm -f ~/.bash_history' Both steps are needed. 'history -c' clears what you see in the history command. 'rm -f ~/.bash_history' deletes the history file in your home directory.

recursively change file name from uppercase to lowercase (or viceversa)

easier way to recursively change files to lowercase using rename instead

Add directory to $PATH if it's not already there

Sometimes in a script you want to make sure that a directory is in the path, and add it in if it's not already there. In this example, $dir contains the new directory you want to add to the path if it's not already present. There are multiple ways to do this, but this one is a nice clean shell-internal approach. I based it on http://stackoverflow.com/a/1397020. You can also do it using tr to separate the path into lines and grep -x to look for exact matches, like this: $ if ! $(echo "$PATH" | tr ":" "\n" | grep -qx "$dir") ; then PATH=$PATH:$dir ; fi which I got from http://stackoverflow.com/a/5048977. Or replace the "echo | tr" part with a shell parameter expansion, like $ if ! $(echo "${PATH//:/$'\n'}" | grep -qx "$dir") ; then PATH=$PATH:$dir ; fi which I got from http://www.commandlinefu.com/commands/view/3209/. There are also other more regex-y ways to do it, but I find the ones listed here easiest to follow. Note some of this is specific to the bash shell.

Easily find latex package documentation

If the pdf/dvi/etc documentation for a latex package is already part of your local texmf tree, then texdoc will find and display it for you. If the documentation is not available on your system, it will bring up the package's webpage at CTAN to help you investigate.

Shrink more than one blank lines to one in VIM.

display a smiling smiley if the command succeeded and a sad smiley if the command failed

you could save the code between if and fi to a shell script named smiley.sh with the first argument as and then do a smiley.sh to see if the command succeeded. a bit needless but who cares ;)
