问题描述
我有一个很长的文件要打印，例如跳过前 1,000,000 行.
I have a very long file which I want to print, skipping the first 1,000,000 lines, for example.
我查看了 cat 手册页，但没有看到任何选项可以执行此操作.我正在寻找执行此操作的命令或简单的 Bash 程序.
I looked into the cat man page, but I did not see any option to do this. I am looking for a command to do this or a simple Bash program.
推荐答案
你需要尾巴.一些例子:
You'll need tail. Some examples:
$ tail great-big-file.log
< Last 10 lines of great-big-file.log >
如果您确实需要跳过特定数量的第一"行，请使用
If you really need to SKIP a particular number of "first" lines, use
$ tail -n +<N+1> <filename>
< filename, excluding first N lines. >
也就是说，如果要跳过 N 行，则开始打印第 N+1 行.示例:
That is, if you want to skip N lines, you start printing line N+1. Example:
$ tail -n +11 /tmp/myfile
< /tmp/myfile, starting at line 11, or skipping the first 10 lines. >
如果你只想看到最后这么多行，请省略+":
If you want to just see the last so many lines, omit the "+":
$ tail -n <N> <filename>
< last N lines of file. >
