The way you're doing it, command is a string; not an awk condition to be processed. Since the string $3 == hello is not an empty string and does not evaluate to "0", testing the string yields TRUE. The following should work but it gets a lot more complex if the operator you want varies from invocation to invocation rather than being a constant ==

Hello world,
I was wondering if there is a nicer way to write the following code (in AWK):
awk '
FNR==NR&&$1~/^m$/{tok1=1}
FNR==NR&&$1~/^m10$/{tok1=1}

In fact, it looks for m2, m4, m6, m8 and m10 and then return a positive flag. The problem is how to define 10 thanks... (3 Replies)
