3. rar command usage
Example 1: Add a file or directory to the compressed file and use the command.
Deleting file (the original file1 file will be deleted after compression is completed. Note: The m command only operates on the file)
[Root @ localhost ~] # Rar a abc.rar file1
Note: If a file1 file already exists in the abc.rar file, the file1 file will be updated. And the original file1 file still exists in the current directory. If you want to move file1file to file1.rar, run the m command. You can also perform this operation on the directory.
Note: If you only enter the "rar a file1.rar" command but do not have a file name or directory name, all the files and directories under the current directory will be compressed into the file1.rar file. Pay attention to this.

Example 2: Decompress the content in the abc.rarfile. You can use the EOR xcommand. Assume that the directory abc.rar contains a file named file1 and a directory named test. The directory test contains a file named file2,
[Root @ localhost ~] # Rar e abc.rar# Not recommended
NOTE: With the ecommand, The file1 file in abc.rar, together with the file2 file in the test directory, will be decompressed to the current directory. If you want to keep the directory structure in the abc.rar directory, use the x command.
[Root @ localhost ~] # Rar x abc.rar# Recommendation
Note: The file1 file and the test directory will be decompressed to the current folder.

Example 3: add comments to the entire compressed file
[Root @ localhost ~] # Rar c abc.rar
Note: The command is displayed at the bottom of the screen.
Processing archive test.
RarReading comment from stdin
And there is a cursor flashing, from the cursor blinking position input comment information, input the end of the input press Ctrl + D

Example 4: add comments to a single file in the compressed file and use the cf Command. If you want to add comments to the file1 file in the abc.rar file
[Root @ localhost ~] # Rar ch abc.rar file1
At the bottom of the screen
Reading comment for abc.rar: file1 from stdin
The comment to be added for file1 is flashed from the cursor, and Ctrl + D is used to end the input.

Example 4: Write the comment of the entire file into a file and use the cw command. To add abc.rarto the test.txt File
[Root @ localhost ~] # Rar cw abc.rar test.txt
Note: If a file named test.txt does not exist in the current directory, a file named test.txt will be created and written into the text.txt Text Example file.

Example 5: delete the files or directories in the compressed file and run the d command. For example, delete the file1 file in the abc.rar file.
[Root @ localhost ~] # Rar d abc.rar file1
Note: This command deletes the file1 file in the abc.rar file, which is also valid for directories.

Unrar command:
[Root @ localhost ~] # Unrar -- help

Usage: unrar <command>-<switch 1>-<switch N> <archive> <files...>
<@ Listfiles...> <path_to_extract \>

<Command>
E. decompress the file to the current directory.
L [t, B] list compressed document information [technical, bare]
P print the file to the standard output
T test compression I am Russian
V [t, B] lists detailed information about compressed documents [technical, bare]
X decompress the file to the complete path

The unrar command has the same effect as the rar command. It can be seen that the unrar command only contains a part of the rar command. Therefore, the rar command can be used to complete all operations.

The parameters are as follows:
<Command>

A add file to zip file
C add archive comments (the maximum size of comments cannot exceed 62000 bytes)
Cf add file remarks (show file remarks when using 'v' parameter, Max. 32767 bytes)
Ch changes the archive parameters
Cw writes a file note to the specified file
D delete the file from the archive
E unzip the file to the current directory (no subdirectories are created)
F refresh the files in the archive (update the changes to these files since they were packaged, not add new ones to the archive)
I [par]=< STR > looks for specific characters in the file
Lock the file (any command that attempts to change the contents of the compressed file will be ignored)
L [t,b] list archives [technical, bare]
M [f] moved to archive [file only]
P print the file to standard output
R fixes compressed files
Rc rebuild the lost volumes
Rn renames files in a compressed archive
Rr [N] adds data recovery record
Rv [N] creates the recovery volume
Conversion between s[name|-] archive and SFX(self-extracting document)
