问题描述

谁能告诉我如何打印行数用awk包括零？

Can anyone tell me how to print line numbers including zero using awk?

下面是我的输入文件<一个href=\"https://onedrive.live.com/redir?resid=73C0B2AE8E459B12!138&authkey=!AO1vZBZKP4QnBFE&ithint=file%2ctxt\"相对=nofollow> stackfile2.txt

当我运行下面的awk命令，我得到<一个href=\"https://onedrive.live.com/redir?resid=73C0B2AE8E459B12!139&authkey=!AO1vZBZKP4QnBFE&ithint=file%2ctxt\"相对=nofollow> actual_output.txt

when I run the below awk command I get actual_output.txt

awk '{print NR,$0}' stackfile2.txt | tr " ", "," > actual_output.txt

而我期望的输出是<一个href=\"https://onedrive.live.com/redir?resid=73C0B2AE8E459B12!143&authkey=!AON7KfT-xDHtJ1g&ithint=file%2ctxt\"相对=nofollow> file.txt的

我如何打印开始行号零（0）？

How do I print the line numbers starting with zero (0)?

推荐答案

NR从1开始，所以使用

NR starts at 1, so use

awk '{print NR-1 "," $0}'
