in reply to Increment Letter on a Command Line

You can avoid the many escapes by using single quotes and reading the letter from STDIN: 
$ echo 'a' | perl -pe 'chomp; $_++; $_.=$/'
b

This uses the magic increment, not by ascii values - but you get the picture.

    Don't forget "-l" (for chomping on input and adding $/ on output). It really helps keep your one-liners slim and trim: 
    $ echo 'a' | perl -lpe '$_++;'
b
