Need help parsing a string

Hi,
I'm writing a shell script that outputs, among other things, some of the information that is outputted by the mysqladmin status command.

The output of the command looks like this:
Uptime: 816351 Threads: 19 Questions: 80719739 Slow queries: 1419 Opens: 15903523 Flush tables: 1 Open tables: 4948 Queries per second avg: 98.879

I need to output the Queries per second, Open tables, and Threads. I know I can count the words on the line and do a cut, but I'd rather do it in a neater fashion.

Is there an easy way to parse this line so that it ouputs:
Uptime: xxxx
Threads: xxx
etc.

and once I have it in that format, I can parse to get the values I want.

Thanks.

You could try -

Code:

#!/bin/sh

FILE="output.txt"

awk '{ print "Uptime " $2 "\nThreads " $4 "\nQuestions: " $6 }' $FILE

# OR

awk '{ print $1 $2 "\n" $3 $4 "\n" $5 $6 }' $FILE
