It's inspired by Generate MD5 hash for a string() [ http://goo.gl/ObCrl ], you need to install hashalot(very small) first. Salt is not necessary.

There is an optional command:

sha256 -s salt -x <<<"test"

So you have a web site and you've plastered your significant other's name all over it. But you broke up with them and have some new love in your life. How do you find all those instances of their name and replace them?

rhost() { if [[ $1 =~ ^[0-9]+$ ]]; then sed -i "$1"d ${HOME}/.ssh/known_hosts; else echo "rhost [n]"; fi }

Quickly remove the conflicting line (key) from current users known_hosts file when there is an SSH host conflict. Very nice when you get tired of writing out full commands. Ideally you would place this into your .bash_profile

Usage: rhost [n]

Example: rhost 33 (removes line 33 from ~/.ssh/known_hosts)

Function assumes the $HOME exists, you could alternatively use "~/.ssh/known_hosts"
