ShellCheck all the bash/sh script under a specific directory excluding version control
This is a commodity one-liner that uses ShellCheck to assure some quality on bash and sh scripts under a specific directory. It ignores the files in .git directory. Just substitute "./.git/*" with "./.svn/*" for older and booring centralized version control. Just substitute ShellCheck with "rm" if your scripts are crap and you want to get rid of them :)

Print all lines in a file that are not a certain length
Alternatively, print all the lines that are a certain length: $awk 'length($0)==12 {print}' your_file_name

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

Bash scripts encryption and passphrase-protection
This function will encrypt a bash script and will only execute it after providing the passphrase. Requires mcrypt to be installed on the system.

"hidden" remote shell
opens a "hidden" remote shell (login will not appear in "last" for example). This is not really hidden, because the login will be shown in auth.log and the process is visible anyways. ssh -T = Disable pseudo-tty allocation. bash -i = interactive shell

Nice info browser
pinfo package provide a nice info alternative based on ncurses.

Replace 'csv_file.csv' with your filename.
