using rot13 and tr command for having an encrypted email address

Not sure exactly how you want to use this, but here’s a basic example to get you started:

echo '[email protected]' | tr 'A-Za-z' 'N-ZA-Mn-za-m'

To make it easier, you can alias the tr command in your .bashrc file thusly:

alias rot13="tr 'A-Za-z' 'N-ZA-Mn-za-m'"

Now you can just call:

echo '[email protected]' | rot13
