How to store the output of a command in an array line by line in perl?

Question

For eg, I want to store the contents of the command ipconfig in an array, such that each line of output is stored in a new index of array, i.e. array[0] contains the 1st line output. array[1] contains the 2nd line output and so on.

How can I achieve that?

I would assign the captured output using backticks into a `scalar`, and use `spilt` and reassign it to an `array`. That's one way to go about it. — Ghost, Sep 01 '16 at 06:42
No, no, no @Ghost. Backticks in list context already captures the output into an array, one `$/`-ending line per element. — mob, Sep 01 '16 at 13:44
@mob: Oh! I wasn't aware of that. Thanks for letting me know about this. Will keep this in mind going further — Ghost, Sep 02 '16 at 09:39

A simple

@array = `ipconfig`;

does the trick. Note that, as Borodin rightly points out, the array elements so assigned include the newlines.

@Coder: Remember that each line in the array will be terminated by a newline character which, depending on your application, may need to be chomped. – Borodin Sep 01 '16 at 07:37
Got it! Thanks :) – Coder Sep 01 '16 at 08:53
