Subject: File.delete one-liner

Hi guys,

I'm looking for a single line that essentially deletes the lockfile
argument passed to the unlock method, or deletes the instance variable
(default) lockfile. Like this, but simpler:

@lockfile = some_other_lockfile

def self.unlock(lockfile)
  if File.exist?(lockfile)
    File.delete(lockfile)
  else
    File.delete(@lockfile)
  end
end


I was thinking of something along the following:

@lockfile = some_other_lockfile

def self.unlock
  File.delete(lockfile) || File.delete(@lockfile)
end

...however, the File.delete method doesn't return a true/false value
based on its success.

Any tips? Thanks in advance!

-David
