Subject: Re: Removing ^M character from text

Thanks for the String#inspect, that really helps.
I am trying to do a regexp match on the first line only of this text, I 
used the output from text.inspect:

"CPU utilization for five seconds: 4%/1%; one minute: 2%; five minutes: 
2%\r\n"
"PID QTy       PC Runtime (ms)    Invoked   uSecs    Stacks TTY 
Process\r\n"
"1 Cwe 40E8BAAC           80       1574      50 5560/6000   0 Chunk 
Manager   \r\n"
"2 Csp 41AD34D0       107060   19504749       5 2600/3000   0 Load Meter 
\r\n"
"3 Mwe 41E1244C            8       8260       0 5136/6000   0 MPLS MIB 
traps  \r\n"
"4 Mwe 403D9860         1580     812729       1 5544/6000   0 DHCPD 
Timer     \r\n"
"5 Lst 40E9F268    211247688   17501448   12070 5616/6000   0 Check 
heaps     \r\n"

I thought it would be as simple as:

        /^CPU\sutilization.*\r\n/

but this returns all the text I have shown above. Why is it that my 
regexp doesn't stop at the "\n"?

thanks
