Re: Disable output from system

In addition to what already has been said, here other variations:

qx(tar ...); # Burns more CPU cycles, but who cares ;-)
use File::Spec::Functions qw(devnull);
system('tar .... >'.devnull.' 1>&2'); # works on *nix and windoze

Hi, Roland. You wrote: system('tar .... >'.devnull.' 1>&2'); # works on *nix and windoze As I can see you redirect STDOUT to devnull and then again you redirect STDOUT to STDERR... Is this correct? I think it is typo, isn't it?	[reply]

you redirect STDOUT to devnull and then again you redirect STDOUT to STDERR... Is this correct? Sorry, a typo indeed. Of course you have to do something like `'....>'.devnull.' 2>&1'` [download] and not "1>&2". I mistakingly exchanged 2 and 1. My point was that you have to redirect first to devnull, and then do the 2>&1, not the other way around. -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l]
