在linux中，可以利用sed命令删除文件的前几行，该命令可依照脚本的指令来处理、编辑文本文件，能够配合正则表达式实现删除文件前几行的效果，语法为“sed -i '1,前几行行数d' 文件名”。

本教程操作环境：linux7.3系统、Dell G3电脑。

linux怎么删除文件前几行

sed -i '1,nd' 文件名
这个是删除第一行到第n行

sed是一种流编辑器，它是文本处理中非常好的工具，能够完美的配合正则表达式使用，功能不同凡响。处理时，把当前处理的行存储在临时缓冲区中，称为“模式空间”（pattern space），接着用sed命令处理缓冲区中的内容，处理完成后，把缓冲区的内容送往屏幕。接着处理下一行，这样不断重复，直到文件末尾。文件内容并没有改变，除非你使用重定向存储输出。

Sed主要用来自动编辑一个或多个文件，可以将数据行进行替换、删除、新增、选取等特定工作，简化对文件的反复操作，编写转换程序等。

语法

sed [-hnV][-e
