Linux deletes files or folders with special characters

The Linux system enables users to create files or folders that contain hyphens (-), and an incorrect operation may sometimes result in the following files or folders:

[[email protected] aa]# touch /tmp/aa/{,-, \\}-{0,1,2,3,4,5}[[email protected] aa ]# ls-0  --0  \-0  -1  --1  \-1  -2   --2  \-2  -3  --3  \-3  -4  --4  \ -4  -5  --5  \-5[[email protected] aa]# lltotal 0-rw-r--r--  1 root root 0 Apr  2 22:52 -0-rw-r--r-- 1 root  Root 0 apr  2 22:52 --0-rw-r--r-- 1 root root 0 apr   2 22:52 \-0-rw-r--r-- 1 root root 0 apr  2 22:52  -1-rw-r--r-- 1 root root 0 Apr  2 22:52 --1-rw-r--r--  1 root root 0 apr  2 22:52 \-1-rw-r--r-- 1 root root  0 apr &nBsp;2 22:52 -2-rw-r--r-- 1 root root 0 apr  2 22:52 --2 -rw-r--r-- 1 root root 0 apr  2 22:52 \-2-rw-r--r-- 1  Root root 0 apr  2 22:52 -3-rw-r--r-- 1 root root 0  apr  2 22:52 --3-rw-r--r-- 1 root root 0 apr  2  22:52 \-3-rw-r--r-- 1 root root 0 apr  2 22:52 -4- rw-r--r-- 1 root root 0 apr  2 22:52 --4-rw-r--r-- 1  Root root 0 apr  2 22:52 \-4-rw-r--r-- 1 root root 0  apr  2 22:52 -5-rw-r--r-- 1 root root 0 apr  2  22:52 --5-rw-r--r-- 1 root root 0 apr  2 22:52 \-5

When we try to delete with normal RM, we will prompt:

[[email protected] aa]# rm-f--0rm:unrecognized option '--0 ' Try ' rm--help ' for more information.

View the RM man manual with the following description:

To remove a file whose name starts with a '-', for example '-foo ', use one of these commands:rm---foo RM./-foo

Use this method to delete the file with \ \ should be aware of two escapes, otherwise it cannot be deleted.

[Roo[email protected] aa]# rm-f--\-5[[email protected] aa]# ls-0--0 \-0-1--1 \-1-2--2 \-2-3--3 \-3-   4--4 \-4--5 \-5[[email protected] aa]# rm-f./\-5[[email protected] aa]# ls-0--0 \-0-1--1 \-1-2--2 \-2 -3--3 \-3-4--4 \-4--5 \-5

The correct approach is as follows:

[[email protected] aa]# rm-f--\\-5[[email protected] aa]# ls-0--0 \-0-1--1 \-1-2--2 \-2-3--3 \-3-4  --4 \-4--5[[email protected] aa]# rm-f./\\-4[[email protected] aa]# ls-0--0 \-0-1--1 \-1-2--2 \-2-3 --3 \-3-4--4--5

The deletion of the folder is the same as this.

You can also delete by using the Inode number:

[Email protected] aa]# Ls-li | grep---22752777-rw-r--r--1 root root 0 Apr 2 22:52-22752783-rw-r--r--1 root root 0 Apr 2 22:52--2[[email Protect Ed] aa]# find. -inum 2752783-exec rm {} \; [Email protected] aa]# Ls-li | grep---22752777-rw-r--r--1 root root 0 Apr 2 22:52-2
