How to unzip, gunzip, untar files with Ruby

Ruby posted 3 months ago by christian

This is a very advanced and resource efficient algorithm for expanding compressed content with Ruby:

   1  def gunzip(filename)
   2    command = "gunzip --force #{filename}"
   3    success = system(command)
   4    
   5    success && $?.exitstatus == 0
   6  end

To customize, change gunzip to whatever command you like.

For example, to avoid 100% CPU utilization during uncompression, set the niceness value of the command with nice -n 5 <command>:

   1  command = "nice -n 5 gunzip --force #{filename}"

There’s also ionice…
