Hello guys!

I am a newbie in ruby and i have a question. I run a system command and i
want that the ouput of that command to be assigne to a variable, something
like this:

var1 = system("du -s /mnt/hdd/ | cut -f1") puts var1  or 

var1 = exec("du -s /mnt/hdd/ | cut -f1") puts var1

but system return 0 or 1 if command is failed or succesful, and exec don't
assigne the output to variable var1.

Can you help me? Thanks in advance.
