Better way to kill files?

Cory

Purpose here is to find all files > 5 hours old in a directory and wipe
them...

Of course I could just write a shell script but I wanted to leverage
ruby...or, rather, needed to leverage ruby...not real familiar with the
File and FileUtils API just yet...

dir_path = "~/foo/bar"

Dir.new(dir_path).each {|file|
if file.include?('foobar')
afile = File.new("#{dir_path}/#{file}")

if (Time.now - afile.mtime)/60/60 > 5
File.delete("#{dir_path}/#{file}")
end
end
}

Not to discourage you from doing it in ruby, but you don't need to
write a shell script:

$man find

$find ~/foo/bar -mmin 300 -delete

ruby -e '`find ~/foo/bar -mmin 300 -delete`'

In case the boss says it has to be Ruby :)

Of course you might want to generate a log of what got deleted.
Or perhaps just to stdout...
Then again, you might even want to do that and move them to a temp
dir for later deletion if they're not important.
Definitely want a log of anything that fit the requirements but was
unable to delete!
