Find broken symlinks and delete them
This command is adapted from http://otomaton.wordpress.com/2012/12/26/find-broken-symbolic-links/ Solutions with $ find -L don't work when the link is a loop, an error message is printed.

Go to the previous sibling directory in alphabetical order
Based on linkinpark342 suggestion. Sometimes you have to browse your way through a lot of sub-directories. This command cd to the previous sub-directory in alphabetical order. For example, if you have the directories "lectures/01-intro", "lectures/02-basic", "lectures/03-advanced" and so on, and your PWD is "02-basic", it jumps to "01-intro".

Recompress all files in current directory from gzip to bzip2
Find all .gz files and recompress them to bz2 on the fly. No temp files. edit: forgot the double quotes! jeez!

Lookup hostname for IP address

use jq to validate and pretty-print json output
the `jq` tool can also be used do validate json files and pretty print output `cat file.json | jq` available on several platforms, including newer debian-based systems via `#sudo apt install jq`, mac via `brew install jq`, and from source https://stedolan.github.io/jq/download/

kill a process(e.g. conky) by its name, useful when debugging conky:)

Using the urxvt terminal daemon
- for .xsession use - Advantages of running a urxvt daemon include faster creation time for terminal windows and a lot of saved memory. You can start new terminals as childs of urxvtd by typing urxvtc. Another advantage is, that background jobs are always owned by the urxvtd and will survive as long the daemon is running.

Open Remote Desktop (RDP) from command line and connect local resources
The above command will open a Remote Desktop connection from command line, authenticate using default username and password (great for virtual machines; in the exampe above it's administrator:password), create a shared folder between your machine and the other machine and configure resolution to best fit your desktop (I don't like full screen because it make the desktop panels to disappear). The command will run in the background, and expect to receive parameters. You should enter hostname or IP address as a parameter to the command, and can also override the defaults parameters with your own.

From Vim, run current buffer in python

Remove a range of lines from a file
