Shell Programming and Scripting

Heyo all,
I'm looking for the most effective way to capture the text in between a set of parenthesis.

For example, my input is this(IBM WebSphereMQ Queue Manager Status):
QMNAME(Q1) STATUS(Ended immediately)
QMNAME(Q2) STATUS(Ended immediately)

And I would like to know how to grab just the text in between the first set of parenthesis. The text "Q1", "Q2" and so on. I've done some digging on this but have been able to find anything that works so far. I'd also be curious to know how I could capture the second instance of the parenthesis text as well. In the future I may have a use for that ability.

Thanks to anyone with any suggestions.

given some assumptions....

Code:

echo 'QMNAME(Q1) STATUS(Ended immediately)' | nawk -F '[()]' 'NF>1{ for(i=2; i <= NF; i=i+2) print $i}'

I don't have nawk available, but I simply changed your example to use "awk" instead and it works well. I suppose I can come up with another script to exclude the various status messages that are possible, such as "Ended Immediately" etc. to keep the list down to just the QMNAME list. Thank you.

This is what I have come up with to capture only Queue Manager names and igonore "Ended immediately", as well as remove blank lines.

dspmq outputs the following text:

QMNAME(Q1) STATUS(Ended immediately)
QMNAME(Q2) STATUS(Ended immediately)
QMNAME(Q3) STATUS(Ended immediately)
QMNAME(Q4) STATUS(Ended immediately)
QMNAME(Q5) STATUS(Ended immediately)



dspmq | awk -F '[()]' 'NF>1{ for(i=2; i <= NF; i=i+2) print $i}' | sed s/Ended//g | sed s/immediately//g | sed -n -e '/^[^ ][^ ]*$/p'

Try:
dspmq | sed -n '/QMNAME/s/.*(\(..\)).*/\1/p'

This also seems to work, but doesn't seem to include a queue manager with a different name other than the "Q1" format. For example it doesn't display "TESTQUEUEMANAGER".

Code:

echo 'QMNAME(TESTQUEUEMANAGER) STATUS(Ended immediately)' | sed -n 's/QMNAME(\([^)][^)]*\)).*/\1/p'
