# Run the system command +cmd+. If multiple arguments are given the command
# is run directly (without the shell, same semantics as Kernel::exec and
# Kernel::system).
#
# It is recommended you use the multiple argument form over interpolating
# user input for both usability and security reasons. With the multiple
# argument form you can easily process files with spaces or other shell
# reserved characters in them. With the multiple argument form your rake
# tasks are not vulnerable to users providing an argument like
# <code>; rm # -rf /</code>.
#
# If a block is given, upon command completion the block is called with an
# OK flag (true on a zero exit status) and a Process::Status object.
# Without a block a RuntimeError is raised when the command exits non-zero.
#
# Examples:
#
# sh 'ls -ltr'
#
# sh 'ls', 'file with spaces'
#
# # check exit status after command runs
# sh %{grep pattern file} do |ok, res|
# if !ok
# puts "pattern not found (status = #{res.exitstatus})"
# end
# end
