Get the Volume labels all bitlocker volumes had before being encrypted
Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided). Note that the volume labels can have spaces, but only if you name then before encryption. Renaming a bitlocker partition after being encrypted does not have the same effect as doing it before.

Substrings a variable
substrings a variable starting at position. If no offset given prints rest of the line

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"

Typing the current date ( or any string ) via a shortcut as if the keys had been actually typed with the hardware keyboard in any application.
That works in all softs, CLI or GUI... I don't want to waste time to all the time typing the same stuff . So, I have that command in my window manager shortcuts ( meta+l ). All the window managers have editable shortcuts AFAIK. If not, or you don't want to use it that way, you can easily use the xbindkeys soft. I you're using kde4, you can run : $ systemsettings then open "inputs actions" and create a new shortcut. For Gnome take a look there : http://www.cyberciti.biz/faq/howto-create-keyboard-shortcuts-in-gnome/ A more advanced one, with strings and newlines : $ xvkbd -xsendevent -text "---8

Open-iscsi target discovery

add files to existing growable DVD using growisofs
replace "directory name with files to add to DVD" with actual directory containing files you want to add to growable DVD

Recurse through directories easily
This is a simple case of recursing through all directories, adding the '.bak' extension to every file. Of course, the 'cp $file $file.bak' could be any code you need to apply to your recursion, including tests, other functions, creating variables, doing math, etc. Simple and clean recursion.

Create passwords and store safely with gpg
Adjust the $ head -c part for password length. I use filenames like "hans@commandlinefu.com.gpg" and a vim which automatically decrypts files with .gpg suffixes.

type partial command, kill this command, check something you forgot, yank the command, resume typing.
Example : $ vim /etc/fstab ## damn $ $ sudo ## like a boss. Example 2 : $ sudo vim /root/bin/ ##uh... autocomplete doesn't work... $ $ sudo ls /root/bin ##ah! that's the name of the file! $ sudo vim /root/bin/ ##resume here! Thanks readline!
