CentOS + rar + unrar install rar unrar command details first write down the two most common rar commands to package the 21andy.com directory as andy.rar www.2cto.com # rar andy.rar. /21andy.com/decompress andy.rar to the current directory # rar x andy.rar CentOS + rar + unrar install www.2cto.com # vi/etc/yum. repos. d/dag. repo put the following content in [dag] name = Dag RPM Repository for Red Hat Enterprise Linux baseurl = http://apt.sw.be/redhat/el?releasever/en/?basearch/dag gpgcheck = 1 enabled = 1 gpgkey = http://dag.wieers.com/rpm/ Packages/RPM-GPG-KEY.dag.txt and then directly install yum # yum-y install rar unrarrar + unrar command details # rar -- help usage: rar <command>-<Option 1>-<option N> <compressed file> <file...> <@ file list...> <decompress path \> <command> a adds a file to compressed file c and adds compressed file comments (the comment size cannot exceed 62000 bytes) cf add file remarks (the file remarks are displayed when the 'V' parameter is used, and the maximum value cannot exceed 32767 bytes) ch changes the archive compression parameter cw writes archive remarks to the specified file d deletes a file from the archive e decompress the file to the current directory (no subdirectories are created) f.

Note: The <command> part of rar does not contain the "-" number, only the <option> part contains the "-". Pay attention to this. Example 1: Add a file or directory to the compressed file and use the command. For example, run the or m command to upload the file1 file to abc.rar. After compression, the command will delete the original file1 file. Note: the m command only operates on files.) # rar a abc.rar file1 Description: if a file named file1 already exists in the file named "Taobao", the file named "file1" is updated. In addition, the original file1 file still exists in the current directory. To move the file1 file 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 of www.2cto.com: 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. # rar e abc.rar description: use the ecommand to decompress the file1 file in abc.rar together with the file2 file in the test directory to the current directory. If you want to keep the directory structure in the abc.rar directory, use the x command. # Rar x abc.rar Note: The file1 file and the test directory will be decompressed to the current folder. Example 3: add a comment for the entire compressed file # rar c abc.rar Note: After you enter this command, Processing archive test.rar Reading comment from stdin is displayed at the bottom of the screen and a cursor is blinking, enter the comments from the blinking position of the cursor. Press Ctrl + D. Input Example 4: add comments to a single file in the compressed file. Run the cf Command. If you want to add a comment for the file1 file in the abc.rar file # rar ch abc.rar file1, the screen will display the Reading comment for abc.rar at the bottom: file1 from stdin flashes from the cursor to enter the comments you want to add to file1. Ctrl + D end input Example 4: Write the comments of the entire file into a file and use the cw command. Add the abc.rar comment to the test.txt file # rar cw abc.rar test.txt Description: if a file named test.txt does not exist in the current directory, you will create a file named "文. Example 4: delete the file or directory in the compressed file and run the d command. For example, delete the file1 file in the abc.rar file. # Rar d abc.rar file1 Note: This command deletes the file1 file in the abc.rar file, which is also valid for directories. The preceding commands are commonly used for compression and decompression. The <option> section is not described. Please try it by yourself. Unrar: # unrar -- help usage: unrar <command>-<switch 1>-<switch N> <archive> <files...> <@ listfiles...> <path_to_extract \> <command> e. Extract the file to the current directory l [t, B] to list the compressed file information [technical, bare] p print file to standard output t test compression I am Russian when v [t, B] list detailed information of the compressed document [technical, bare] the command for extracting files from x to the complete path unrar has the same effect as rar. It can be seen that unrar only contains a part of rar commands, so you can use rar to complete all operations.
