如何删除一个文件的第一行？ [英] How do I delete the first line in a file?

问题描述

我不能搜索一个特定的字符串，因为他们都非常相似，但我想简单的东西在一个文件中砍出前4行。

I can't search for a particular string, since they're all very similar, but I'd like something simple to chop out the first 4 lines in a file.

他们都变长了。我有一个想一下Perl的，而这一切似乎比我想象的困难，但我想这样做在Perl，AWK或shell命令如果可能的话。

They're all variable length too. I've had a think about perl, and it all seems harder than I thought, but I'd like to do it in Perl, AWK or a shell command if possible.

没有任何人有这样做的一个简单的方法？

Does anybody have a simple way of doing this?

推荐答案

SED 是最简单的。删除文件的第一行，这样做：

sed is the simplest. To delete the first line of a file, do:

sed '1d' file.txt

或者，要删除前四行，如下：

Or, to remove the first four lines, do:

sed '1,4d' file.txt
