Linux deletes files with special characters

Sometimes we need to delete some files with special characters, but we don't know how to delete them, like I do, and here are some of the ways I've learned to delete: rm–-filename rm./-filename RM * some* rm-i * through inode number to understand RM syntax

First understand the following RM syntax, in fact, I did not have a good understanding of ‵‵‵‵‵, in the terminal window to type Rm–help

[Root@localhost tmp]$ rm--help usage:rm [OPTION] ...
FILE ...

  Remove (unlink) the FILE (s). -F,--force ignore nonexistent files and arguments, never prompt-i prompt, before every REM  Oval-i prompt once before removing than more three files, or when removing recursively; Less intrusive than-i, while still giving protection against most mistakes--interactive[ =when] Prompt According to When:never, once (-i), or always (-i);
                          Without when the prompt always--one-file-system when removing a hierarchy recursively and skip any Directory This is on a file system different from this of the corresponding command line AR Gument--no-preserve-root do not treat '/' specially--preserve-root does not remove '/' (default)-R, R,
 --recursive Remove directories and their contents recursively -D,--dir remove empty directories-v,--verbose explain what are being done--help Displa  Y this Help and exit--version output version information and exit by default, RM does not remove directories.

Use the--recursive (-r or-r) option to remove each listed directory, too, along and all of its contents. To remove a file whose name starts with a '-', for example '-foo ', use one of these commands:rm---foo rm./-foo N OTE that if your use RM to remove a file, it might is possible to recover some of its contents, given sufficient  and/or time.

For greater assurance the contents are truly unrecoverable, consider using shred. GNU coreutils online Help:  
using the Rm–-filename command to remove 
RM directly deletes the file with the start of the filename, prompting for failure

[Root@localhost tmp]# rm-er.txt
rm:invalid Option--' e '
Try ' rm./-er.txt ' To remove the ' file '-er.txt '.
Try ' rm--help ' for the more information.
 
Use rm–-filename Delete, note that RM is followed by two-

[Root@localhost tmp]# RM---er.txt
rm:remove Regular empty file '-er.txt '? y
[root@localhost tmp]# ls
link
  [root@localhost tmp]#
 
You can see that-er.txt has been removed using the RM./-filename command

When you use the rm–-filename command to delete a file, you are prompted to try using RM./-er.txt to delete files

[Root@localhost tmp]# rm./-er.txt 
rm:remove Regular Empty file './-er.txt '? y
[root@localhost tmp]# ls
l Ink
 
You can see that-er.txt has been removed using the RM *some* command

Sometimes, some files with special characters are encountered, using Rm–-filename or using RM./-filename also deleted, you have to use the RM some command to delete, such as to delete? *&sni.txt this file
This command should be used with caution, * is a wildcard, you may delete the files with some characters

[Root@localhost tmp]# ll total
0
-rw-rw-r--. 1 root   0,  9 12:10-er.txt
-rw-rw-r--. 1 Root   root   0,  9 12:10-rr20170109122610.txt
-rw-rw-r--. 1 Chenzl Chenzl 0,  9 14:05?*& Sni.txt
[root@localhost tmp]# rm--? *&sni.txt

file '-er.txt '? Bash : Sni.txt:command not found

-rw-rw-r--. 1 ro OT root 0,  9 12:10-rr20170109122610.txt
[root@localhost tmp]#
 
Use the rm-i * command to delete 
If you use the above methods still can't delete, you can try the ultimate big strokes, such as I want to delete? *&sni.txt this file, when the hint is want to delete the file, enter Y, otherwise enter n

[Root@localhost tmp]# ll total
0
-rw-rw-r--. 1 Chenzl Chenzl 0 before  9 14:14? *&sni.txt
-rw-r--r--. 1 ro OT   root   0  9 14:15 testfile
[root@localhost tmp]# rm-i * rm:remove regular empty
file '? *&sni . txt '?  Y
rm:remove regular empty file ' testfile ' n
[root@localhost tmp]# ll total
0
-rw-r--r--. 1 root 0  9 14:15 testfile
[root@localhost tmp]#
 
Delete by inode number 
can also be deleted by the inode number of the file, first find the document inode number, using Ls-il can see, such as? *&sni.txt the inode number for this file is 74150596, and then the file is deleted with the Find command.

[root@localhost tmp]# Ls-il total
0
74150596-rw-rw-r--. 1 Chenzl Chenzl 0 before  9 14:27? *&sni.txt
671 32857-rw-r--r--. 1 root   0  9 14:15 testfile
[root@localhost tmp]# find.-inum 74150596-exec {} \;
Rm:remove regular empty file './?*&sni.txt '? Y
 
When the use of one of these methods does not work, the text of several methods are tried, if still not, I will not be able to ‵‵‵‵‵‵‵, but I believe the final big strokes can be done.
