External bash script in Ruby?

How to run an external bash (or any language) script in Ruby? Or directly within Ruby e.g. "pacman -Sy".

you mean system("command")?

Yes.
Example, to run /usr/bin/hwd (bash script) from a Ruby script. What's the command to rum an external script?

I think what wam meant is that you use the <code>system</code> command in Ruby, so the syntax would be:

system("/usr/bin/hwd")

Got this from mindtriggerz, developing Pry (Pacman Ruby).

%x{this is a command}

Example:

%x{/usr/bin/hwd}

%x{ is a nice shorthand way of doing things, but for dynamic things, Kernel.system is better
