hi
I am trying to execute the following unix command through perl script and put the result in array, but the output of the array is always 0. For exaple: if the output that I got from Unix is 'Hello Othello', the value which stored in $returncode is 0.

My code is:

my $returncode = system("grep $value /usr/share/lib/dict/words");
my @array1 = split/ /, $returncode;

system() does not return output. It returns the exit status.

Use qx// or backtiks `` to capture output

my $returncode = qx|grep $value /usr/share/lib/dict/words|;

or you could just use perls grep function.

Thank you, KevinADC
