Can i use 'sysem' command with @array

[JaybOt]

Hi all,

Can anyone help with this one. i'm trying to use the 'system' command in a foreach loop with a perl array but can't get it to work. Heres what i'm doing ...

foreach (@ARRAY)
{
system('dig -x [@ARRAY] hinfo');
next
}

the DNS lookup is being done on "@ARRAY". The array contains a list of ip addersses, 1 per line.

any help welcome.

when you say

foreach (@ARRAY)
{
.
.
.
}

you're really saying

foreach $_ (@ARRAY){

because foreach sets $_ unless you tell it otherwise

you could re-write your loop like this

foreach $addr (@ARRAY)
{
system("dig -x $addr hinfo"
}

(you don't need the "next" by the way) Mike
