Piping a System commmand to a Perl variable...

[juanmj]

Hi,

I want to be able to obtain the output of a system command to a perl variable ..

Example:
Something like this:

my $variable = system ("users"

But what I want in the variable is the output of the executed system command "users"...

Any Ideas???

Thanks ....

Backticks is a good way of accomplishing this, for example:
my $variable = ´users´;
would capture teh output and put it in the scalar variable.
//Daniel

<grin> Pardon me Daniel but those are forward ticks..... I think you mean:

my $variable = `users`;

Better way if you have multiple lines:

open (IN, &quot;users|&quot;
while (<IN>) {
do something interesting...
}
close (IN)
