I made a compilation of Ruby one-liners [1] as well last year.

There's plenty of stuff that is similar to Perl, which in turn had borrowed from awk, sed and other tools. The biggest difference I'd pick is Perl's context based operation.

    # Ruby requires explicit conversion with to_i
    ruby -ane 'print if $F[1].to_i > 35'
    perl -ane 'print if $F[1] > 35'

Performance is slower compared to Perl, but to those who already know Ruby, this would suit better than learning the nuances of another language.
