Top Forums Shell Programming and Scripting Capture the last record number using "awk" NR variable Post 302991241 by rbatte1 on Wednesday 8th of February 2017 08:20:38 AM

If it is a trivial count, then commands like wc can give you this, however I think the easiest way using awk (if you are really doing some processing of the data in awk) is to have a count incremented each time you read a record, then in the END section, display the count.

Would this work for you?:-
Code:
awk '{c=NR;print c ; records++} END {print records}' abc.txt

Obviously adjust it to your preferences. The above will print a line number for every record read AND the final record count, so this might not be what you want. I would only go with awk if you are doing some other processing. wc is far simpler.



I hope that this helps,
Robin
