FileUtils.mv Pointless Errno::ENOENT

Ruby

Noticed that when $DEBUG=true, any FileUtils.mv call produces two
(rescued) exceptions:

$ ls
sim-1.0.0.zip
$ irb

$DEBUG=true
=> true

FileUtils.mv(‘sim-1.0.0.zip’, ‘sm.zip’)
Exception Errno::ENOENT' at /usr/lib/ruby/1.8/fileutils.rb:1420 - No such file or directory - sm.zip ExceptionErrno::ENOENT’ at /usr/lib/ruby/1.8/fileutils.rb:1200 - No
such file or directory - sm.zip
