Call a program

[greg]

Hi all,

Can anyone help me with the following issue: How can I call a program
(such as less, g++ etc.) from ruby script and save the output to a
variable inside the ruby script?

Thanks,
Greg

The easiest forms are these

x=`ls -l`
x=%x{ls -l}

For more complex interactions please look at various versions of popen.

Kind regards
