Uses history to get the last n+1 commands (since this command will appear as the most recent), then strips out the line number and this command using sed, and appends the commands to a file.

Uses UNIX time for sorting.

Just increase the 1 at the end if you want to generate more than one.

(Alternative to "| head -n N" you could use the -b flag of od: -b $[6*N]

this command will beep like an alarm for one minute from 18:57. you can change "1857" to your desired time.

you should have alsa-oss package installed, and you should also be root or part of "audio" group.

Work only with bash and apt-file installed.

When it found an unknow command, it will search for a file named "scribus" (in my example), in a folder named bin and then install the corresponding package.

After installation, it will run the command.

Usefull juste after reinstalling linux and missing lot of package.

Pros: the format is very simple, there is no need to show every columns, and full command with args

the first column is memory consumption %

the second column is pid

the third is just the command (without full arguments, most application's arguments are too long)

You can decide which application to kill then.

Prepending

env LC_CTYPE=C

fixes a problem with bad bytes in /dev/urandom on Mac OS X

This is a simple command which makes electricsheep render directly to your background

Will work with filenames with spaces inside. Will not break in case of someone making directory that matches *.pm. And sorts from largest. Where largest is file size, not line count.

Changed wget to curl and it doesn't create a file anymore.

Substitute that 724349691704 with an UPC of a CD you have at hand, and (hopefully) this oneliner should return the $Artist - $Title, querying discogs.com.

Yes, I know, all that head/tail/grep crap can be improved with a single sed command, feel free to send "patches" :D

Enjoy!

finger - gets logged in users

grep $(whoami) - greps only the current user (if there are more logged in)

head -n1 - just one line

awk '{print $2 " " $3}' - second and third word, seperated with a space (the users name)

OT: My first commandlinefu-command :)

Show the top file size in human readable form

Little faster alternative.
