Check These Out

for loop with leading zero in bash 3

your terminal sings
you know the song... sing along

generate a randome 10 character password

Selecting a random file/folder of a folder
Also looks in subfolders

list files recursively by size

Save a file you edited in vim without the needed permissions (no echo)
Write a file you edited in Vim but that you do not have the permissions to write to (unless you use sudo.) Same as #1204 but without the echo to stdout that I find annoying.

Generate an XKCD #936 style 4 word passphrase (fast)
Some snippets posted are slow on big dictionaries, this one is fast.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

clean up syntax and de-obfuscate perl script
the command show can be run in vim, here is the same thing on the command line $ cat script.pl | perl -MO=Deparse | perltidy

Generate a random password 30 characters long
This command is similar to the alternate, except with head(1), you can pick as many passwords as you wish to generate by changing the number of lines you wish to preview.
