Re: Re: system & shell metacharacters

I'm with you. I'd use something like

open BAR, '|bar.pl' || die qq(Useful msg: $!);
print BAR $xmldata;
[download]

and let bar.pl read from STDIN. No shell at all. OP might want a glance at perlipc.

`open BAR, '\|bar.pl' \|\| die qq(Useful msg: $!);` ... is wrong, because it is interpreted as: `open BAR, ('\|bar.pl' \|\| die qq(Useful msg: $!));` ... so remember to use "or die" rather than "\|\| die".	[reply] [d/l] [select]

Using `\|\| die` is fine as long as parens are used. `open(FOO, $file) \|\| die "Couldn't open $file - $!\n";` [download] When no parens are present, you should use `or die` instead. Personally, I always use parens everywhere so my code is littered with `\|\| die`s. -- vek --	[reply] [d/l] [select]
