Update Ogg Vorbis file comments
The "vorbiscomment" utility lets you update information such as artist names and song and album tags in an Ogg Vorbis file. You can use this command to fix any mistakes that were made when ripping an album.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Load your [git-controlled] working files into the vi arglist.
Branch name may be substituted, of course.

ssh batch jobs: query hundreds of hosts with an ssh command
Need to query hundreds of hosts with an ssh command ? Of course you'll have setup keys on all your remote HOSTs. But in the case a key is not present this command will skip that node, proceeding on to the next. -t: Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine. Also prevents unwanted stty messages being sent to console -q: Quiet mode. -o "BatchMode yes" If set to yes, passphrase/password querying will be disabled. This option is useful in scripts and other batch jobs where no user is present

List known debian vulnerabilities on your system -- many of which may not yet be patched.
You can search for CVEs at https://security-tracker.debian.org/tracker/ or use --report to get full links. This can be added to cron, but unless you're going to do manual patches, you'd just be torturing yourself.

find external links in all html files in a directory list
Just a handy way to get all the unique links from inside all the html files inside a directory. Can be handy on scripts etc.

Show directories in the PATH, one per line
Shorter version.

Decrypt MD5
Decrypt MD5 , replace 1cb251ec0d568de6a929b520c4aed8d1 with the MD5 string you want to decrypt

Enable ** to expand files recursively (>=bash-4.0)
Since bash 4.0, you can use ** to recursively expand to all files in the current directory. This behaviour is disabled by default, this command enables it (you'd best put it in your .profile). See the sample output for clarification. In my opinion this is much better than creating hacks with find and xargs when you want to pass files to an application.

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