p - print
q - quit

Hm... good point... actually, my test directory had only directories under it... so that's an oops.

Hi,

I have got a question.

Quote:
ls -ltr|awk 'NR==2 {print $NF}'
ls -ltr|awk '!/total/ {print $NF;exit}'
should show the 2nd row right. How come it's showing only the last field? Please explain.

Yes, but it also says '{print $NF}' so it prints only the last field (NF holds the number of fields in the line, so $NF refers to the last field).

ls -ltr|awk 'NR==2 {print $NF}'
ls -ltr|awk '!/total/ {print $NF;exit}'
