extract string from varying delimiter line
Hi
I have lines like this
a=1, b=2, c=3,
a=1, d=4, e=5, b=225,
I need to extract the b=nnn... value. I dont know how many other entries will be before and after it in each line. Ive tried a basic line like
awk '/b=/, $NF ~ /,/ ' myfile.txt
but I think that it doesnt care which comma it picks.
I to begin the selection with b= and end it with the NEXT comma after b=
Any ideas?
Thanks.
