Limit the output of the TOP command to a specific process name

I prefer the following so I can still use top interactively without having to look up the pids each time I run it:

top -p `pgrep process-name | tr "\\n" "," | sed 's/,$//'`

Of course if the processes change you’ll have to re-run the command.

Explanation:

• pgrep process-name returns a list of process ids which are separated by newlines
• tr "\\n" "," translates these newlines into commas, because top wants a comma-separated list of process ids
• sed is a stream editor, and sed 's/,$//' is used here to remove the trailing comma
