3. rar command Usage
Example 1: Add a file or directory to a compressed archive, using the a command.
For example, add the file files1 to Abc.rar, use the A or M command, a command to add the File1 file to the Abc.rar file to keep the original file1 files unchanged, M command to move the file1 file into the File1.rar files ( When the compression is complete, the original file1 file is deleted, note: The M command is only for the file operation)

[email protected] ~]# rar a abc.rar file1

Note: If the Abc.rar file does not exist at this time, the Abc.rar file will be created on its own; if the Abc.rar files already exist, the file1 files will be compressed into the Abc.rar files, and if a Abc.rar file already exists in the file1 files, the File1 file will be updated. And the original File1 file still exists in the current directory, to move the file1 file to File1.rar, use the M command, which is also available for the directory.
Note: If you enter only the "rar a File1.rar" command instead of the file name or directory name, all the files and folders in the current directory will be compressed into the File1.rar document. Pay attention to this point.
Example 2: Extract the contents of the Abc.rar file, you can use the E or X command, assuming that the Abc.rar directory has a file named File1 and a directory named Test, the test directory has a file named File2,

[email protected] ~]# rar e abc.rar  #不推荐

Note: Using the e command, the File1 file in Abc.rar is extracted to the current directory along with the File2 file in the test directory. If you want to keep the directory structure in the Abc.rar directory, use the x command.

[email protected] ~]# rar x abc.rar #推荐

Description: The File1 file and the test directory are extracted to the current folder.

Example 3: Add comments for the entire compressed file

[[email protected] ~]# rar c Abc.rar

Note: When you enter this command, the bottom of the screen is displayed

Processing archive test.rarreading comment from stdin

And there is a cursor blinking, enter the comment information from the position where the cursor blinks, enter the end input by pressing CTRL+D

Example 4: Write a note of the entire file to a file, using the CW command. Join to write comments for Abc.rar to the Test.txt file

[[email protected] ~]# rar CW Abc.rar test.txt

Note: If a file named Test.txt is not present in the current directory, a file named Test.txt will be created on its own, and Abc.rar's comments will be written to the Text.txt file. If a file named Text.txt already exists in the current directory, you are prompted to overwrite the file that already exists, and if you select Yes or all, the contents of the test.txt are emptied, and the Abc.rar comment content is written to the Text.txt file.

Example 5: Deleting a file or directory in a compressed archive, using the D command. For example, to delete the File1 file in the Abc.rar archive.

[[email protected] ~]# rar d abc.rar file1

Note: This command removes the File1 file from the Abc.rar archive and is also valid for the directory.

Unzip the command Unrar using:

[Email protected] ~]# Unrar--help

Usage:

Unrar <command>-<switch 1>-<switch n> <archive> <files...>           < @listfiles ...> <path_to_extract\>

< commands >

e Extract the files to the current directory
l [t, b] List compressed file information [technical, bare]
p print file to standard output
t test compression i russian
v [t, b] lists detailed information for compressed documents

Unrar commands and RAR have the same effect, you can see that Unrar contains only a part of the RAR command, so the use of RAR can do all the operation.

The parameters are as follows:
< commands >

a Add files to compressed archive
  c Add a compressed archive comment (the size of the comment cannot exceed 62000 bytes)
  cf add file comments (display file comments when using the ‘v’ parameter, the maximum cannot exceed 32767 bytes)

  d delete files from archive
  e Extract the files to the current directory (do not create any subdirectories)
