Rot13 using the tr command

alias rot13="tr '[A-Za-z]' '[N-ZA-Mn-za-m]'"
rot13 maps a..mn..z (A..MN..Z) to n..za..m (n..za..m) and so does this alias.

No need for quotes or square brackets: alias rot13="tr a-zA-Z n-za-mN-ZA-M"

That's a great solution. The second one, the function only needs a small correction. As written, the digit part only rotates the digit 10 places. To rotate it 13 places, use the following range: [3-90-2]
