Welcome to ExecuteShell

ExecuteShell provides cross-platform shell command execution. In other words, it lays the smack down like a hungry t-rex in the octagon with a pig.

Getting Started

Install ExecuteShell at the command prompt if you haven't yet:

$ gem install execute_shell

Require the gem in your Gemfile:

$ gem 'execute_shell', '~> 1.0.1'

Require the gem wherever you need to use it:

require 'execute_shell'

Usage

Simply call ExecuteShell.run as needed:

result = ExecuteShell.run('ls ~')

result will be a ShellResult object containing information regarding the executed command.

Available methods include:

out ...... Standard out.
err ...... Standard error.
success? . Whether the command was executed successfully.
to_s ..... Standard out and standard error concatenated.

If you wish to simply get a single success, output, or error value back,

   you may use calls such as:

ExecuteShell.run_success?('ls ~')
ExecuteShell.run_out('ls ~')
ExecuteShell.run_err('ls ~')
ExecuteShell.run_to_s('ls ~')

These may be chained together and will be returned in an array in the order they are specified:

ExecuteShell.run_out_err('ls ~')
ExecuteShell.run_to_s_success_out('ls ~')
ExecuteShell.run_err_out_success('ls ~')

Additional Notes

• The run method has a second optional parameter, which is a path. If specified, the working directory will be changed to this path prior to executing the shell command. It will be set back to the original working directory before returning to the calling function.

• Success is based on the content of the err attribute of ShellResult.
