Subject: How to capture output of linux command


You can run linux command:

a = `ls /home`

and receive output in variable a.

But I would like /home to be variable. So I would invoke command like
this:

a = `"ls #{dir}"`

This of course doesn't work, but I hope you get the point.

a = system("ls #{dir}") works, but returns only true or false not the
standard output of command.

How can I get standard output of the command and use variable as
parameter?
