Provides a simplified interface to shelling out yet still collecting both standard out and standard error and providing full control over environment, working directory, uid, gid, etc.
No means for passing input to the subprocess is provided.
Invoke find(1) to search for .rb files:
find = Mixlib::ShellOut.new("find . -name '*.rb'")
find.run_command
If all went well, the results are on stdout
puts find.stdout
find(1) prints diagnostic info to STDERR:
puts "error messages" + find.stderr
Raise an exception if it didn't exit with 0
find.error!
Run a command as the www user with no extra ENV settings from /tmp
cmd = Mixlib::ShellOut.new("apachectl", "start", :user => 'www', :env => nil, :cwd => '/tmp')
cmd.run_command # etc.
Mixlib::ShellOut does a standard fork/exec on Unix, and uses the Win32 API on Windows. There is not currently support for JRuby.
