Problem with KPRocIO

Hi,

I'd like to run a sequence like this
cat /proc/stats | grep processes | cut -f 2 -d " "

with KProcIO.

KProcIO Proc();
Proc << "cat /proc/stats | grep processes | cut -f 2 -d \" \""

this doesn't work

Proc << "cat" << "/proc/stats" << "| grep processes" << "| cut -f 2 -d \" \""

also doesn't work

even

Proc << "echo Hello" doesn't work.

but

Proc << "echo" << "Hello" works.

How can i run such a command line in order to get its result via stdout ?

Thanks.

RE: Problem with KPRocIO

Just a guess:

Proc << "cat" << "/proc/stats" << "|" << "grep" << "processes" << "|" << "cut" << "-f" << "2" << "-d" << " ";

proc.setUseShell(true)
and use the all-in-one-string variant IIRC.
