bcd

Sort of “cd with bookmarks” for Zsh. You define bookmarks for directories in ~/.bcdrc and then use:

bcd some-bookmark

to cd to the directory associated with some-bookmark. Format of ~/.bcdrc is:

name:directory

e.g.:

ul:/usr/local
uls:/usr/local/stow
nspool:/var/spool/news

With that you can use:

$ bcd uls

to cd to /usr/local/stow.

Calling bcd without arguments prints the bookmarks:

$ bcd
       ul --> /usr/local
      uls --> /usr/local/stow
   nspool --> /var/spool/news

bcd comes with completion for Zsh:

$ bcd ul<TAB>
Completing bcd bookmarks
       ul --> /usr/local
      uls --> /usr/local/stow

bcd needs Zsh but should work with any POSIX /bin/sh if you remove the completion stuff at the end of the file.

cntclass

Counts the class attributes used in a HTML document.

Needs xmllint distributed with libxml

$ cntclass  http://www.florian-diesch.de

     1 nav
     1 navactiveitem
     1 navlevel0
     1 navopen
     1 validate

     3 navlevel1
     4 navpassiveitem
     5 navitem

dave

Ask HAL about your hardware.

Calling dave with two arguments $1 and $2 lists all device objects for which key $1 has the string value $2.

Calling dave with three arguments $1, $2 and $3 lists the value of key $3 for all device objects for which key $1 has the string value $2.

Note that $2 always refers to string value so dave doesn’t work for keys that have values of other types. That’s a limitation of hal-find-by-property .

Needs hal-find-by-property, hal-get-property and lshal (all distributed with HAL).

$ dave block.device /dev/sda
udi = '/org/freedesktop/Hal/devices/storage_serial_SATA_WDC_WD800BB_22J_WD_WCAM9C068403'
 block.device = '/dev/sda'  (string)
 block.is_volume = false  (bool)
 block.major = 8  (0x8)  (int)
 block.minor = 0  (0x0)  (int)
 ...

$ dave linux.subsystem input info.product
ImPS/2 Logitech Wheel Mouse
Macintosh mouse button emulation
AT Translated Set 2 keyboard
PC Speaker
Power Button (CM)
Power Button (FF)

dvdtime

Prints the total play time if all tracks on a video DVD.

Needs lsdvd. Maybe it only works with GNU date (didn’t check if the needed features are defined by POSIX)

$ dvdtime /dev/dvd
libdvdread: Using libdvdcss version 1.2.10 for DVD access
01:10:57

ffprofiles

Prints the names of the currently used Firefox profiles. Tested with Firefox 3.0.x

Needs lsof, GNU xargs

$ ffprofiles
default
test

openlnk

Open a Windows .lnk file in Linux. This script is the result of a discussion on ubuntuusers.de

By default it looks for the file on the same partition as the .lnk file. You can define a mapping between Windows drive letters and Linux mountpoints in ~/.openlnkrc that has to look similar to this:

C: /media/C
D: /some/other/mount point

The script parses .lnk files just by searching for something that looks like a Windows file name. It doesn’t deal well with non-ASCII characters in file names.

Files are opened using xdg-open.

pypicats

Downloads the classifier list from PyPI, displays a list where you can select classifiers and prints the selected classifiers.

Needs zenity, tempfile and wget

sleepuntil

Sleep until a given time. See the date documentation for how to specify times.

Needs GNU date.

$ sleepuntil '0:00'
$ sleepuntil tomorrow
$ sleepuntil '0:01 1/1 next year'

switch-to-pid

Switches to a window of the application that has a give PID.

Needs wmctrl.

$ switch-to-pid $(pgrep firefox)
