How to execute an external program - Ruby equivalents to PHP

PHP has these:

shell_exec – Execute command via shell and return the complete output
as a
string
system – Execute an external program and display the output
passthru – Execute an external program and display raw output
exec – Execute an external program

And a few more that I don’t use. Does Ruby have equivalents? I am
especially
intersted in a shell_exec counterpart.

thanks

backticks:

result = echo Hello World!

Thanks!

There are a few others, like #system (I believe). Check out the
documentation for Kernel.
