in reply to Help to monitor a PID

Let's say I have a process called 'abc'. The command:  pgrep -f 'abc' returns: 3184 A character dump (on Linux):  pgrep -f 'abc' | od -c shows: 
0000000   3   1   8   4  \n
0000005

Spot the trailing new-line. To scrap the newline, read the Learning Perl article on Using Backquotes to Capture Output.
