Syntax: zip [-AcdDfFghjJKlLmoqrSTuvVwXyz $] [-B <工作目录> ] [-Ll] [-n <字尾字符串> ] [-T <日期时间> ] [- <压缩效率> ] [Compressed file] [file...] [-I <范本样式> ] [-X <范本样式> ]

Note: zip is a widely used compression program. after files are compressed, other compressed files with the ". zip" extension will be generated.

Parameters:

-A: adjust the executable automatic decompression file.

-B <工作目录> Specifies the directory for storing files temporarily.

-D. delete the specified file from the compressed file.

-D. The directory name is not created in the compressed file.

-F this parameter works similarly to the specified "-u" parameter, but not only updates existing files, if some files do not exist in the compressed file, this parameter is used to add it to the compressed file.

-F tries to repair damaged compressed files.

-G compresses the file and attaches it to the existing compressed file, instead of creating a new compressed file.

-H online help.

-I <范本样式> Only files that meet the criteria are compressed.

-J only saves the file name and its content, without storing any directory name.

-J: delete unnecessary data before the compressed file.

-K uses a file name in MS-DOS-compatible format.

Linux unzip command details

Function description: decompress the zip file.

Syntax: unzip [-cflptuvz] [-agCjLMnoqsVX] [-P <密码> [[.Zip file] [file] [-d <目录> ] [-X <文件> ] Or unzip [-Z]

Note: unzipis the decompression program for. ZIP compressed files.

Parameters:

-C displays the extracted results on the screen and converts the characters properly.

-F: update an existing file.

-L displays the files contained in the compressed file.

The-p parameter is similar to the-c parameter. the decompressed result is displayed on the screen, but no conversion is performed.

-T check whether the compressed file is correct.

The-u parameter is similar to the-f parameter, but in addition to updating existing files, other files in the compressed file are also extracted to the directory.

-V retains the file version information of VMS.

-X: saves the original UID/GID of the file at the same time during decompression.

. ZIP file] specifies the. zip compressed file.

[File] specifies the files in the. zip compressed file to be processed.

-D <目录> Specifies the directory to be stored after the file is decompressed.

Example:

The zip command can be used to compress files into common zip formats. The unzip command is used to decompress the zip file.

1. I want to compress a file abc.txtand a directory dir1into yasuo.zip:

# Zip-r yasuo.zip abc.txt dir1

2. I downloaded a yasuo.zip file and want to decompress it:

# Unzip yasuo.zip

3. I have abc1.zip, abc2.zip, and abc3.zip under the current directory. I want to decompress them together:

# Unzip abc \?. Zip

Note :? Represents a single character. if "*" is used, it indicates any number of characters.

4. I have a large compressed file large.zip. I don't want to decompress it. I just want to see what it contains:

# Unzip-v large.zip

5. I downloaded a compressed file large.zip and want to verify whether the downloaded file is complete.

# Unzip-t large.zip

6. I used -v8.0 to find that there are many directories and subdirectories in the music.zip compressed file, and the subdirectories are actually mp3 files. I want to download these files to the first-level directory instead of the first-level Directory:

# Unzip-j music.zip
