Bash – linebreaks between results in grep

bashgrep

I need to occasionally monitor a spider that I have running on my server. I'm testing it to see how many iterations of it are running concurrently and to see if any of them are hanging.

I use this:

echo `ps -ewwo args | grep '^[^ ]*curl'`

and the output is all in one line. If I change that to 

echo `ps -ewwo args | grep -n '^[^ ]*curl'`

I get the line numbers, but the output is still all in one line. How do I get it to break the results into separate lines?

As a test, I did something like 

grep "br" /home/user/www/index.php

and it found many instances and output them each on a separate line, just like I want I to.

If you don't quote the output of a `...` subshell, the linebreaks will be replaced with spaces. If you want the linebreaks then don't use a `...` subshell, just run the commands and let them do the outputting by themselves, without using echo at all, for example:

ps -ewwo args | grep '^[^ ]*curl'
ps -ewwo args | grep -n '^[^ ]*curl'
