I am trying to execute the following command using perl script :

my $sum = `$sudo $ssh $server netstat -Aan | /bin/grep 1158 | /bin/egrep '@IP[0]' | wc -l`;

Where $sudo = full path to sudo command , same for $ssh , $server = the file server that I want to pull the data from , and @Ip[0] = ip address.

When I run the exact command from the shell (not as a script) I get the required result (which is an integer number). However , when I run the script it just gets hangs when it reaches to that point.

I cant see anything wrong with the syntax , I am using back ticks to save the returned output , could you please assist?

You probably have to change `@IP[0]` to `$IP[0]`. – redneb Sep 07 '16 at 07:13
Tried your suggestion to change from @IP[0] to $IP[0] and issue persists. – CleverDev Sep 07 '16 at 07:18

@DineshPundkar , I cant paste the command online , but believe me it is working. – CleverDev Sep 07 '16 at 07:20
Hi , @ChankeyPathak , thanks for the suggestion , but this didnt not solve the problem . I escaped it that way: \'@IP[0]\' – CleverDev Sep 07 '16 at 07:23

Please print output of the following: `my $command = qq{$sudo $ssh $server netstat -Aan | /bin/grep 1158 | /bin/egrep $IP[0] | wc -l}; print $command;` – Chankey Pathak Sep 07 '16 at 07:25
