[Linux Learning] Essential Linux Commands (1) – Detailed explanation of the rm command

1.Detailed explanation of commands

The rm command is mainly used to delete files or directories. The usage is rm –rf test.txt (-r means recursion, -f means force). The common parameters are explained in detail below:

用法:rm [选项] 文件		删除 (unlink) 文件。
-f, --force 			强制删除。忽略不存在的文件,不提示确认;
-i 						在删除前需要确认;
-I 						在删除超过三个文件或者递归删除前要求确认。此选项比-i
						提示内容更少,但同样可以阻止大多数错误发生;
-r, -R, --recursive 	递归删除目录及其内容;
-d, --dir            	删除空目录
-v, --verbose 			详细显示进行的步骤;
--help 					显示此帮助信息并退出;
--version 				显示版本信息并退出;
默认时,rm 不会删除目录,使用--recursive(-r 或-R)选项可删除每个给定的目录,以
及其下所有的内容;
要删除第一个字符为"-"的文件 (例如"-foo"),可使用:rm -- -foo或rm ./-foo
