shell equivalent of a boss button
Nobody wants the boss to notice when you're slacking off. This will fill your shell with random data, parts of it highlighted. Note that 'highlight' is the Perl module App::highlight, not "a universal sourcecode to formatted text converter." You'll also need Term::ANSIColor.

Display a block of text with AWK
I find this terribly useful for grepping through a file, looking for just a block of text. There's "grep -A # pattern file.txt" to see a specific number of lines following your pattern, but what if you want to see the whole block? Say, the output of "dmidecode" (as root): $ dmidecode | awk '/Battery/,/^$/' Will show me everything following the battery block up to the next block of text. Again, I find this extremely useful when I want to see whole blocks of text based on a pattern, and I don't care to see the rest of the data in output. This could be used against the '/etc/securetty/user' file on Unix to find the block of a specific user. It could be used against VirtualHosts or Directories on Apache to find specific definitions. The scenarios go on for any text formatted in a block fashion. Very handy.

list block devices

Find usb device in realtime

Purge configuration files of removed packages on debian based systems

Search and play youtube videos directly to terminal (no X needed)
Same as other command, however uses youtube-dl internal search (thanks to qoxxxx mentioning this) It does however seem to be a little buggy and youtube-dl crashes sometimes. ## pyt 'Stairway to heaven - Led Zeppelin' pyt 'brain damage - Pink Floyd' No web browser or even X needed. Just a cli and internet connection! mplayer is pauseable and can skip ahead This may break if youtube changes their search html.

rgrep: recursive grep without .svn
Only excludes .svn from filenames.

Bash autocomplete case insensitive search
Change bash autocomplete case search to insensitive when pressing tab for completion.

Find size in kilobyte of files that are deleted but still in use and therefore consumes diskspace
