Question

I am executing a unix command through perl script to get size of a direcory.

$path = "/dir1/di2/";
system("du -sh $path");

How can I get the result back in my perl script.

I am using

$size = system("du -sh $path");
print $size

But it is giving size=0;

Answer 1

a system call returns the status of the call, not the output. Use backticks (or the qx operator) like:

$size = qx(du -sh $path);
