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"}'

Renames all files in the current directory such that the new file contains no space characters.

This is a better version, as it does no command piping, uses for instead of while loops, which allows for a list of files in the current working directory to be natively processed. It also uses the -v/verbose option with mv to let you know what the command is doing. While the command does exactly the same in a better way, I would modify the sed option to replace spaces with underscores instead, or dashes. Please note that you'll receive errors with this command as it tries to rename files that don't even have spaces.

Switch all connected PulseAudio bluetooth devices to A2DP profile

Tries to switch all audio devices to the A2DP profile for optimal sound quality. Useful for bluetooth speakers and headphones that always power up in HSP/HFP mode. Note however that this command is only a shorthand for the GUI, so it cannot fix stubborn BT controllers that leave your device stuck in HSP mode until a manual re-coupling.

Find Malware in the current and sub directories by MD5 hashes

Command makes use of the Malware Hash Registry (http://www.team-cymru.org/Services/MHR/). It parses the current directory and subdirectories and calculates the md5 hash of the files, then prints the name and sends the hash to the MHR for a lookup in their database. The 3rd value in the result is the detection percentage across a mix of AV packages.

Extract neatly a rar compressed file

It's also possible to delay the extraction (echo "unrar e ... fi" |at now+20 minutes) wich is really convenient!

ssh X tunneling over multiple ssh hosts (through ssh proxy)

Simply makes it possible to launch any X application residing on sshhost through sshproxy and display it on your screen where ever you are.

Fix borked character coding in a tty.

Often you find some tty programs are messed up and confused about character encoding - 'man' is a common problem and sometimes displays weird characters for apostrophes, hyphens etc etc. Another class of programs that suffer from this are those that try to use the line drawing characters - eg RedHat's tty system admin functions such as system-config-firewall-tui system-config-network-tui etc. Adding 'LC_ALL=C' fixes most of these problems (as long as you want English! Perhaps speakers of other languages can add a comment here). For bonus points, I've added the '-c' option to the man command so that it ignores it's cache and re-computes the man page using the C locale.

Find out which debian package a command (executable) belongs to on debian-based distros

This revision to my command (command #8851) was called for when it failed to find the parent package of 'rlogin', which is really a deep symbolic link to /usr/bin/ssh. This revision fixes this newfound issue, while ensuring fixes of other older issues work too.
