Rename files in batch

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.

Capture video of a linux desktop

Tells you where a command is in your $PATH, but also wether it's a link and to what.
You may also use the $(which foo) variant instead of backticks. I personnaly have an alias ll='ls -l'.

Renames all files in the current directory such that the new file contains no space characters.
This is a better version, as it does no command piping, uses for instead of while loops, which allows for a list of files in the current working directory to be natively processed. It also uses the -v/verbose option with mv to let you know what the command is doing. While the command does exactly the same in a better way, I would modify the sed option to replace spaces with underscores instead, or dashes. Please note that you'll receive errors with this command as it tries to rename files that don't even have spaces.

open two files side by side in vim (one window, two panes)

Add temporary entry to authorized_keys
If you frequently need to connect to your ubersecure mainframe from various uberunsafe machines, you have to face difficult decision: (a) type the password everytime during the session (lame), (b) add local public key to mainframes authorized_keys file (unsafe), (c) as above, but remove this key at the end of the session (pain in the a55). So let's say you save The Command to tempauth file in bin directory of your mainframe's account and make it executable. Then, while you're on one of these unsafe ones, do: $ cat $HOME/.ssh/id_rsa.pub|ssh 5z474n@mainframe.nl bin/tempauth 30 and password prompts stop the harassment for 30 minutes and you don't have to care to remove the unsafe key after that.

Notepad in a browser

for all who don't have the watch command
#Usage: watch timeinsecond "command"

if you are working in two different directories; e.g. verifying files in your home directory; ls ~/ and you need to cd to the /etc/directory. you can enter 'cd -' (no single quotes) to go back and forth between directories.
