Remove job from crontab by commandline
The "-u USER" is optional if root user is used

Display the top 10 running processes - sorted by memory usage
A pretty nice display of processes.

Install pip with Proxy
Installs pip packages defining a proxy

Squish repeated delimiters into one
This can be particularly useful used in conjunction with a following cut command like $echo "hello::::there" | tr -s ':' | cut -d':' -f2 which prints 'there'. Much easier that guessing at -f values for cut. I know 'tr -s' is used in lots of commands here already but I just figured out the -s flag and thought it deserved to be highlighted :)

Create a tar archive using xz compression
Compress files or a directory to xz format. XZ has superior and faster compression than bzip2 in most cases. XZ is superior to 7zip format because it can save file permissions and other metadata data.

Content search.
Grep will read the contents of each file in PWD and will use the REs $1 $2 ... $n to match the contents. In case of match, grep will print the appropriate file, line number and the matching line. It's just easier to write $ ff word1 word2 word3 Instead of $ grep -rinE 'word1|word2|word3' .

download specific files only from a website

Rename files in batch

Determine if a port is open with bash
For times when netcat isn't available. Will throw a Connection refused message if a port is closed. Scriptable: $ (: /dev/null && echo "OPEN" || echo "CLOSED"

Rename duplicates from MusicBrainz Picard
Renames duplicates from MusicBrainz Picard, so you get the latest copy and not a bunch of duplicates.
