I HAVE A FILE "TEXT.TXT" WHICH CONTAINS FOLLOWING :

CHANNEL(SYSTEM.DEF.CLUSRCVR) CHLTYPE(CLUSRCVR)
CHANNEL(TO.XYZ) CHLTYPE(CLUSRCVR)

NOW I WANT THE NAMES WRITTEN BETWEEN THE BRACES () UNDER COLUMN ONE, THAT IS, TO.XYZ and SYSTEM.DEF.CLUSRCVR.

USING awk i can get the first column, but then how to proceed further ?
I am doing like this :

sed -n '/CHANNEL/p' TEST.TXT | awk '{print $1 ;}' | tr '()' ' ' | awk '{print $2;}' | tr ')' ' '

And it does the objective , but i want something more presize and good option !!

ASAP Any help, genius ??
Thanks !!
