Hello !

  In that case, the `command` syntax is perfectly adapted. (or system,
for the conversion). In case you need to check the return value of the
`commands`, use $? .

  If you need to work with bigger output, where it would not be suitable
to store it all in a Ruby variable, give a look at IO.popen

  Cheers !
