Rm command is a command to delete files or directories in the Linux system, its function is very powerful, it can recursively delete a directory and all files and subdirectories under it, let's take a look at the detailed use of the rm command in the Linux system.

1. Linux rm command syntax

The syntax of the rm command is very simple, as follows:

Rm [OPTION]... FILE... Note: the rm command is very dangerous, please make sure what needs to be deleted before executing the rm command!

Parameters.

-f,-- force ignores files that do not exist and never gives prompts. -I,-- interactive asks before deleting-r,-R,-- recursive instructs rm to recursively delete all directories and subdirectories listed in the parameter. -v,-- verbose details the steps in progress-- help displays this help and exits-- version outputs version information and exits the developer

1) Delete files

[linuxdaxue.com@/home/linuxdaxue.com/rmTest] $ll total 0-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file1 lrwxrwxrwx 1 linuxdaxue.com linuxdaxue.com 5 Jun 16 21:53 file1_link-> file1-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file2-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:53 file3-rw-r--r-- 1 linuxdaxue.com linuxdaxue Com 0 Jun 16 21:53 file4 [linuxdaxue.com@/home/linuxdaxue.com/rmTest] $rm file4 [linuxdaxue.com@/home/linuxdaxue.com/rmTest] $ll total 0-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file1 lrwxrwxrwx 1 linuxdaxue.com linuxdaxue.com 5 Jun 16 21:53 file1_link-> file1-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file2-rw-r--r-- 1 linuxdaxue. Com linuxdaxue.com 0 Jun 16 21:53 file3 in this example We use the rm command to delete a normal file, but the system does not give a prompt to delete it, but deletes the file directly.

2) Interactive deletion of files

[linuxdaxue.com@/home/linuxdaxue.com/rmTest] $ll total 0-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file1 lrwxrwxrwx 1 linuxdaxue.com linuxdaxue.com 5 Jun 16 21:53 file1_link-> file1-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file2-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:53 file3 [linuxdaxue.com@/home/linuxdaxue.com/rmTest] $rm-I file3 rm: remove regular empty file `file3'? Y [linuxdaxue.com@/home/linuxdaxue.com/rmTest] $ll total 0-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file1 lrwxrwxrwx 1 linuxdaxue.com linuxdaxue.com 5 Jun 16 21:53 file1_link-> file1-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file2 in this example, when we use the rm command plus the parameter-I to delete file3, the system asks whether to delete file3.

3) delete the link

[linuxdaxue.com@/home/linuxdaxue.com/rmTest] $ll total 0-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file1 lrwxrwxrwx 1 linuxdaxue.com linuxdaxue.com 5 Jun 16 21:53 file1_link-> file1-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file2 [linuxdaxue.com@/home/linuxdaxue.com/rmTest] $rm file1_link [linuxdaxue.com@/home/linuxdaxue.com/rmTest] $ll total 0-rw -linuxdaxue.com linuxdaxue.com Murray-1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file1-rw-r--r-- 1 linuxdaxue.com linuxdaxue.com 0 Jun 16 21:52 file2 in this example When we delete file1's link file1_link, the system only deletes the file1's link file, file1 is not deleted.

4) Recursive reinforcement to delete folders

[linuxdaxue.com@/home/linuxdaxue.com] $ls dir1 file_new rmTest src testDir [linuxdaxue.com@/home/linuxdaxue.com] $ls testDir [linuxdaxue.com@/home/linuxdaxue.com] $ls rmTest/ file1 file2 [linuxdaxue.com@/home/linuxdaxue.com] $rm-rf rmTest [linuxdaxue.com@/home/linuxdaxue.com] $ls dir1 file_new src testDir what is the Linux system Linux is a free and freely distributed UNIX-like operating system Is a POSIX-based multi-user, multi-tasking, multi-threaded and multi-CPU operating system, using Linux to run major Unix tools, applications and network protocols.
