Ruby - System Command - ps aux

So, I'm trying to find the PID of any process that has the word "control" in it. I'm in ruby ​​on Linux. This is the basic code so far

`ps aux | grep control`

If I run this in ruby, all the crisp lines that come back when run on linux are concatenated into one long line. How can I read ruby ​​results as a list rather than one long line?

You can break it down to newlines like so:

lines = (`ps aux | grep control`).split(/\n/)


With this, you can iterate over them, select things with a regex, etc.

Since you are on Linux, you can check the / proc filesystem. There are / proc // directories, and / proc // cmdline has a command line.
