sh(*cmd, &block)
Instance Public methods
Run the system command cmd. If multiple arguments are given
the command is not run with the shell (same semantics as Kernel::exec and
Kernel::system).
Example:
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
