Zip unzip compression and decompression under Linux

NOTE: * Compress into limited. zip format files

Common decompression:

[Email protected] test]# Unzip-o test.zip-d tmp/

Unzip the compressed file Test.zip under the specified directory TMP , and require the unzip command to overwrite the original file if the same file exists.

Common compression:

[Email protected] test]# zip-r test.zip./*

All files and folders under the current directory are compressed into test.zip files, and-R indicates that all files in the subdirectory are compressed recursively.

The following commands are all operated under the/home directory
Cd/home #进入/home Directory
1. Compress the MyData directory below the/home directory to Mydata.zip
Zip-r Mydata.zip MyData #压缩mydata目录

2. Unzip the mydata.zip under the/home directory into the Mydatabak directory
Unzip mydata.zip-d Mydatabak

3, the home/home directory below the ABC folder and 123.txt compression becomes abc123.zip

Zip-r abc123.zip ABC 123.txt
4. Extract the Wwwroot.zip from the/home directory directly into the/home directory

Unzip Wwwroot.zip
5, the Home/home directory under the Abc12.zip, Abc23.zip, abc34.zip simultaneously extracted to the/home directory

Unzip Abc\*.zip
6. View the contents of the wwwroot.zip inside the/home directory

Unzip-v Wwwroot.zip
7. Verify that the wwwroot.zip under the/home directory is complete

Unzip-t Wwwroot.zip
8. Unzip all the files inside the/home directory under Wwwroot.zip to the first level directory

Unzip-j Wwwroot.zip

Main parameters
-C: Results that will be decompressed
-L: Displays files contained within the compressed file
-P: Similar to the-c parameter, the extracted results are displayed on the screen, but no conversions are performed
-T: Check that the compressed file is correct
-U: Similar to the-f parameter, but other files in the compressed file are extracted to the directory in addition to updating the existing file
-V: Show detailed information when performing Yes
-Z: Show only notes text for compressed files
-A: Necessary character conversions for text files
-B: Do not convert text files to characters
-C: File names in compressed files are case-sensitive
-j: does not handle the directory path of compressed files
-L: Change all file names in the compressed file to lowercase
-M: Send output to more program processing
-N: Do not overwrite the original file when decompressing
-O: Do not ask the user first, overwrite the original file after unzip execution
-p< Password: Use the zip password option
-Q: Do not display any information when executing
-S: Converts white space characters in file names to baseline characters
-V: Keep the file version information of the VMS
-X: Uid/gid The original file while decompressing

Function Description: Compress the file.

Syntax: Zip [-acddffghjjkllmoqrstuvvwxyz$][-b < working directory >][-ll][-n < tail string >][-t < date time >][-< compression efficiency >][compressed file [Documents ...] [-i < template style;] [-x < template style;]

Note: Zip is a widely used compression program that compresses files that have a ". zip" extension.

Parameters

-A adjusts the executable auto-unzip file.

-b< working directory > Specifies the directory where files are temporarily stored.

-C adds a comment to each compressed file.

-d deletes the specified file from within the compressed file.

The directory name is not established within the-D compressed file.

-F The effect of this parameter is similar to specifying the "-u" parameter, but not only updates the existing file, and if some files do not already exist in the compressed file, use this parameter to add it to the compressed file.

-F attempt to repair a corrupted compressed file.

-G compresses the file after it is appended to the existing compressed file, rather than creating a new compressed file.

-H online Help.

-i< template style > compress only files that match the criteria.

-j saves only the file name and its contents, not any directory names.

-J Delete unnecessary data before compressing the file.

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

-L When compressing a file, replace the LF character with the LF+CR character.

-ll the LF+CR character into the LF character when compressing the file.

-L displays copyright information.

-M compresses the file and joins the compressed file, deletes the original file, and then moves the file to the compressed file.

-n< string > does not compress a file with a specific trailing string.

-O to compress files that have the most recent change time in the file, set the change time for the compressed file to be the same as the file.

-Q does not show the instruction execution process.

-R recursively handles all files and subdirectories under the specified directory.

-S contains the system and hidden files.

-t< Date Time > Set the date of the compressed file to the specified date.

-T checks that each file within the backup file is correct.

-U replace the newer file into the compressed file.

-V Displays the instruction execution process or displays version information.

-V Saves the file properties of the VMS operating system.

-W in the file name if the version number, this parameter is only valid under the VMS operating system.

-x< template style > exclude files that match the criteria when compressing.

-X does not save additional file attributes.

-Y saves the symbolic connection directly, not the file that the connection points to, and this parameter is only valid under systems such as UNIX.

-Z adds a comment to the compressed file.

-$ Save the volume book name of the disk where the first compressed file is located.

-< compression Efficiency > Compression efficiency is a value between 1-9.

Example

Example 1. Compress test. MYI

[[email protected] test]# zip test1.zip test. MYI

Adding:test. MYI (deflated 42%)

[[email protected] test] #ll

-rw-r--r--1 root root 1033755 09-24 10:03 test1.zip

The compression rate is 8

[[email protected] test]# zip test2.zip-8 test. MYI

Adding:test. MYI (deflated 42%)

[[email protected] test] #ll

-rw-r--r--1 root root 1033451 09-24 10:03 test2.zip

Example 2. All files and folders under the current directory are compressed into test.zip files, and-r means all files in the recursive compressed sub-directory

[Email protected] test]# zip-r test.zip./*

Package Directory

[Email protected] test]# zip test2.zip test2/*

Example 3. Delete test.myi files in compressed file Test1.zip

[Email protected] test]# zip-d test1.zip test. MYI

Remove files from the packaged files directory

[Email protected] test]# zip-d test2.zip test2/ln.log

Deleting:tests/ln.log

Example 4. Add the test. myi file to the Test1.zip in the compressed file

[Email protected] test]# zip-m test1.zip test. MYI

Example 5. Exclude a file when compressing a file

[[email protected] test]# zip test3.zip tests/*-x Tests/ln.log

command name : Unzip

Additional note: Unzip is the unzip program for. zip compressed files.

-N Do not overwrite the original file when extracting.

-O do not need to ask the user first, unzip overwrite the original file after execution.
