[rrd-users] Re: Storing snmpget results in an array

[Stephan Harren]

Quite easy,

try:

@var=qx(snmpwalk ....);

Now you have all your stuff line by line in an array named var.

To access it:

foreach (@var) {
	print "$_\n";
}

Or:

foreach $test (@var) {
	print "$test\n";
}

This way you'll get all the elements printed. Surely you can do anything you 
want with this values instead of printing them ...

HTH,

Stephan
