Re: Re: Redirecting OUTPUT of system($command) to an array

Nkuvu,
I would guess that this is 1 step short of being what is desired ultimately. The output likely needs to be split (by either horizontal or vertical whitespace).

my $command = "/usr/local/some/command";
my $result = `$command`;
my @array = split /\n/ , $result;

Otherwise ~~the entire result ends up in slot 0 of the array~~ you will have no control over how the output is stored into the array.

Cheers - L~R

Update: If the desired outcome is to split on newlines, then there is no need to store the result into a temporary scalar and split yourself as japhy points out below.

Except that `readpipe()` (which is what implements `...` and `qx()`) returns a list of lines in list context. So an array on the left-hand side is fine. _____________________________________________________ Jeff`[japhy]`Pinyan: Perl, regex, and perl hacker, who'd like a job (NYC-area) `s++=END;++y(;-P)}y js++=;shajsj<++y(p-q)}?print:??;`	[reply]

Thanks for the caveat, I'll keep that in mind. So far, every time I've resorted to using backticks, the system command I've been executing has output multiple lines of information.	[reply]
