Re^3: One liner: remove ssh keys with quotemeta

While you are correct that the default shell can be a strange critter, the questioner's existing code assumes Bourne-like shell quoting rules, so I offered an example that follows suit.

A better answer would probably be to write the update routines entirely in Ruby instead of calling out to other programs, but this is PerlMonks, not RubyMonks. :-)

A simple read-modify-write shouldn't be that hard in Ruby, making it ~~atomar~~ atomic by writing to a new file followed by a rename shouldn't be hard, either.
