Hi,
Could anyone please explain why we have arr=1 - what does this statement do?
awk -F\; 'FNR==NR{arr=1;next};$3 in arr' core.txt gmrd.txt
Any help appreciated (2 Replies)
As I know:
FNR: The ordinal number of the current record in the current file.
NR: The ordinal number of the current record from the start of input.

Thanks (1 Reply)

Hi,
Is there anyway to alter this command so that if it does not find a match it will just leave the line alone instead of replacing what it doesn't find with a blank space? (4 Replies)
Example:

6The following awk script works like a charm, NR==FNR is true for file1, the remainder runs for file2:
awk '
NR==FNR {A; next}
($1 in A)
