All the other answers here are fine answers. In many situations, you do need to run external commands.

This specific example has another option: you can read the file, process it line by line, and do something with the output.

While this answer doesn't work for the "more general question being asked", I think it should always be considered. It is not always the "right answer", even where possible. Remembering this (easier), and knowing when (not) to apply it (more difficult), will make you a better programmer.
