Description

This gem brings command execution via POpen4 with all the bells and whistles.

Usage

require 'command_exec'

#long form
command = CommandExec::Command.new( 'command' )
command.run

#short form
command = CommandExec::Command.execute( 'command')

#full path to commadn
command = CommandExec::Command.execute( 'path/to/command')

# available options
command = CommandExec::Command.new(
  'command',
  :logger => Logger.new($stderr),
  :options => '--command options',
  :parameter => 'command parameter',
  :error_keywords => ['key words in', 'stdout with indicate errors' ],
  :working_directory => 'working/directory/where/the/command/should/be/executed/in',
  :logfile => 'path/to/logfile.log',
  :debug => false,
  )
command.run
