This directly puts the "mirror" into fullscreen, and lets you take photos by pressing the 's' key. I bet appearance conscious people will have keyboard shortcut for this command by now.

ssh user@machine_A dd if=/dev/dvd0 > dvddump.iso

Tags: ssh dvd dump

You can use this to directly dump from machine A (with dvd drive) to machine B (without dvd drive) . I used this to copy dvd using my friend's machine to my netbook. Above command is to be issued on machine B.

Advantages :

1) No wasting time dumping first to machine A and then copying to Machine B.

2) You dont need to use space on Machine A. In fact, this will work even when Machine A doesnt have enough hdd space to dump the DVD.

Use -C ssh option on slow networks (enables compression).

you can replace "dd if=/dev/dvd" with any ripping command as long as it spews the iso to stdout.

This helped me find a botnet that had made into my system. Of course, this is not a foolproof or guarantied way to find all of them or even most of them. But it helped me find it.

Tags: Debian dpkg PATH

OS: Debian based (or those that use dpkg)

Equivalent to doing a dpkg -S on each file in $PATH, but way faster.

May report files generated though postinstall scripts and such. For example . It will report /usr/bin/vim .. which is not not a file installed directly by dpkg, but a link generated by alternatives hooks

Functions: find sort

Lists out all classes used in all *.html files in the currect directory. usefull for checking if you have left out any style definitions, or accidentally given a different name than you intended. ( I have an ugly habit of accidentally substituting camelCase instead of using under_scores: i would name soemthing counterBox instead of counter_box)

WARNING: assumes you give classnames in between double quotes, and that you apply only one class per element.

Functions: echo sleep

[Note: This command needs to be run as root].

If you are downloading something large at night, you can start wget as a normal user and issue the above command as root. When the download is done, the computer will automatically go to sleep. If at any time you feel the computer should not go to sleep automatically(like if you find the download still continuing in the morning), just create an empty file called nosleep in /tmp directory.

User: kamathln
Functions: echo find read

Sqlite database keeps collecting cruft as time passes, which can be cleaned by the 'vacuum;' command. This command cleans up the cruft in all sqlite files relating to the user you have logged in as. This command has to be run when firefox is not running, or it will exit displaying the pid of the firefox running.

##Dependancies: bash coreutils

Many executables in $PATH have the keyword somewhere other than the beginning in their file names. The command is useful for exploring the executables in $PATH like this.

find ${PATH//:/ } -executable -type f -printf "%f\n" |grep admin
