Unlock your KDE4.3 session remotely

The unlock command for KDE 4.3 has changed from krunner_lock, this process doesn't exist anymore. So here's the update :-) If qdbus complains about not being able to find X, put a "DISPLAY=:0 " (:0 being your X server display) in front of the command.

Matrix Style

A tweak using Patola's code as a base, this full-width green matrix display has all the frills (and all the printable characters). You don't need the surrounding parens if you don't care about losing globbing capabilities. Z-shell (/bin/zsh) needs neither the parens nor the `set -o noglob` Screen shot (animated): http://desmond.imageshack.us/Himg32/scaled.php?server=32&filename=matrixh.gif&res=landing If it's too slow, try lowering the `sleep 0.05` or even replacing it with `true` (which is faster than `sleep 0`). I squashed it as narrow as I could to conserve space, though somebody could probably squeeze a char or two out. Enjoy!

Unlock your KDE4 session over SSH

So this first obtains address of the DBUS session, as it's not available by default over SSH. Then it tells plasma-overlay to exit. `kquitapp` is pretty much an equivalent of the qdbus calls.

( eval $(grep -z '^DBUS_SESSION_BUS_ADDRESS' /proc/$(pgrep -u $USER plasma-overlay)/environ); export DBUS_SESSION_BUS_ADDRESS; kquitapp plasma-overlay )

Create a visually twisted effect by alternating the direction of the "staples" effect vertically. The effect is achieved by moving odd-numbered lines from right to left and even-numbered lines from left to right.

The effect is achieved by moving odd-numbered lines from right to left and even-numbered lines from left to right. For odd-numbered lines (with an index j), the ((j + i) % 2 == 0) condition is satisfied. In this case, the line width is set to i, resulting in the line moving from left to right. For even-numbered lines, the ((j + i) % 2 == 0) condition is not satisfied. The line width is set to $(tput cols) - i, causing the line to move from right to left. This alternating direction of movement creates a twisted visual effect as the lines appear to move in opposite directions. The code runs in a continuous loop, repeatedly updating the lines with changing background colors. There is a slight pause of 0.05 seconds between each iteration to control the speed of the animation.

Create a bunch of dummy text files

Using the 'time' command, running this with 'tr' took 28 seconds (and change) each time but using base64 only took 8 seconds (and change). If the file doesn't have to be viewable, pulling straight from urandom with head only took 6 seconds (and change)

convert ascii string to hex

Separates each frame of a animated gif file to a counted file, then appends the frames together into one sheet file. Useful for making sprite sheets for games.

requires imagemagick

list block devices

Shows all block devices in a tree with descruptions of what they are.

simplest calculator

Rename all files in lower case

Find all videos under current directory

Uses mime-type of files rather than relying on file extensions to find files of a certain type. This can obviously be extended to finding files of any other type as well.. like plain text files, audio, etc.. In reference to displaying the total hours of video (which was earlier posted in command line fu, but relied on the user having to supply all possible video file formats) we can now do better: $ find ./ -type f -print0 | xargs -0 file -iNf - | grep video | cut -d: -f1 | xargs -d'\n' /usr/share/doc/mplayer/examples/midentify | grep ID_LENGTH | awk -F "=" '{sum += $2} END {print sum/60/60; print "hours"}'

Jump to line X in file in Nano.

Starts the cursor on line X of file foo. Useful for longer files in which it takes a long time to scroll. If X is greater than the number of lines in file foo, it will go to the last existing 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"
