direct output from System command

amoura has asked for the wisdom of the Perl Monks concerning the following question:

Hello guys , I want to direct the output from the following to a file

system qw(update blablblbabal);
[download]

I tried this

chdir "x:";
system qw(update blablblbabal)> $temp/out.txt;
[download]

also this

 
chdir "x:";
system "update blablblbabal)> $temp/out.txt";
[download]

but no luck , in the second one the update don't like >out.txt . ps . the $temp is my current drive not x drive ... any ideas .. thanks

This reminds me of a FAQ in perlfaq8, specifically Why can't I get the output of a command with system()?. If you capture the output, you can open a file in the normal Perl sense.	[reply]

this should do what you want (you should supply better error messages, obviously). i don't know how output redirection works in windows, but this is probably more portable anyhow. `open(B, "update blablblabl \|") or die "noo! $!"; open(O, ">$temp/out.txt") or die "why me! $!"; while(<B>) { print O; } close(B); close(O);` [download]	[reply] [d/l]

If you want to stuff the output of <command> into a file without seeing it in your program you can also do this- `system("command > $temp/out.txt");` [download] You cannot use this method with multiple arguments to system() ie. `system("command", "arg1", "arg2", ">file");` doesn't work. -- my $chainsaw = 'Perl';	[reply] [d/l] [select]
