Regular expression in AWK
Hello world, I was wondering if there is a nicer way to write the following code (in AWK): Code:
awk '
FNR==NR&&$1~/^m[24689]$/{tok1=1}
FNR==NR&&$1~/^m10$/{tok1=1}
' my_file
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 to regular expresions? Is there a way do a list of possible values, like "{2,4,6,8,10}"? Let me know, Thanks |
