ROT13(1)                     GregOS Manual                     ROT13(1)

NAME
       rot13 - rotate ASCII letters by 13 positions

SYNOPSIS
       rot13 <text>

DESCRIPTION
       rot13 applies the ROT13 substitution cipher to the input
       text. Each letter is replaced by the letter 13 positions
       after it in the alphabet, wrapping around from z to a.
       Non-alphabetic characters are passed through unchanged.

       ROT13 is its own inverse: applying it twice returns the
       original text. It is not encryption. It is not even close
       to encryption. Do not use this for anything important.

EXAMPLES
       $ rot13 Hello
       Uryyb

       $ rot13 Uryyb
       Hello
