git pull all repos

Shows users and 'virtual users' on your a unix-type system
Shows a list of users that currently running processes are executing as. YMMV regarding ps and it's many variants. For example, you might need: $ ps -axgu | cut -f1 -d' ' | sort -u

send incoming audio to a Icecast server (giss.tv)
easy way to setup an "internet radio sation", pre-requisite, create an account at an icecast server, in this example, just created beforehand an account at giss.tv. Change the word password, with the respective real password you created at server. Make sure to have installed rec, oggnec, oggfwd and tee. I have a mixer connected at line in, so I can mix music and microphone. This also will produce a local recorded copy of the session, it will be called "streamdump.ogg"

Get all mac address
I prefer the ip command to ifconfig as ifconfig is supposedly going to be deprecated. Certain IP address aliases can only be seen with the ip command (such as the ones applied by RHCS).

find text in a file
this will find text in the directory you specify and give you line where it appears.

Convert JSON to YAML
Convert JSON to YAML. Note that you'll need to have PyYaml installed.

randomize hostname and mac address, force dhcp renew. (for anonymous networking)
this string of commands will release your dhcp address, change your mac address, generate a new random hostname and then get a new dhcp lease.

Detect illegal access to kernel space, potentially useful for Meltdown detection
Based on capsule8 agent examples, not rigorously tested

Deleting / Ignoring lines from the top of a file
Output lines starting at line 2.

Create passwords and store safely with gpg
Adjust the $ head -c part for password length. I use filenames like "hans@commandlinefu.com.gpg" and a vim which automatically decrypts files with .gpg suffixes.
