Linux zip/unzip Command Detailed _linux

Recently cleaned up the Linux zip/unzip command, as follows:

Command name: Zip

Function Description: Compress file.

Syntax: Zip [-acddffghjjkllmoqrstuvvwxyz$][-b < working directory >][-ll][-n < word tail string >][-t < date time >][-< compression efficiency >][Compressed files [Document ...] [-i < template style] [-x < template style]

Supplemental Note: Zip is a widely used compression program, the file after it compression will produce a ". zip" extension of the compressed file.

Parameters

-A adjusts the executable automatic decompression file.

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

-C adds a comment for each compressed file.

-d deletes the specified file from the compressed file.

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

-F The effect of this parameter is similar to the specified "-u" parameter, but not only the existing file is updated, but if some files do not exist in the compressed file, this parameter will be added to the compressed file together.

-F attempts to repair a corrupted compressed file.

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

-H online Help.

-i< template Style > compress only the eligible files.

-j only saves the file name and its contents, without any directory names.

-J Delete unnecessary data before compressing the file.

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

-L replaces the LF character with the LF+CR character when compressing the file.

When-ll compressed files, replace the LF+CR characters with the LF character.

-L displays copyright information.

-M to compress the file and add the compressed file, delete the original file, that is, move the file to the compressed file.

-n< string > Do not compress files with a specific character end string.

-O Sets the time to change the compressed file to the same file as the file that has the latest change time in the compressed file.

-Q does not display the instruction execution process.

-R recursive processing of all files and subdirectories under the specified directory.

-S contains system and hidden files.

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

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

-U replaces the newer file with the compressed file.

-V Displays the instruction execution process or display 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 eligible files when compacting.

-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 valid only for systems such as UNIX.

-Z Adds a comment for the compressed file.

-$ the volume name of the disk on which the first compressed file is stored.

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

Example

Example 1. Compress test. Myi

[root@mysql test]# zip test1.zip test. Myi

adding:test. Myi (deflated 42%)

[root@mysql test] #ll

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

The compression rate is 8.

[root@mysql test]# zip test2.zip-8 test. Myi

adding:test. Myi (deflated 42%)

[root@mysql test] #ll

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

Example 2. Compresses all files and folders in the current directory into Test.zip files,-r means all files in a recursive compressed subdirectory

[Root@mysql test]# zip-r test.zip./*

Packaging Catalog

[Root@mysql test]# zip test2.zip test2/*

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

[Root@mysql test]# zip-d test1.zip test. Myi

Delete files in the packaged files directory

 [Root@mysql 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

[Root@mysql test]# zip-m test1.zip test. Myi

Example 5. Exclude a file when compressing files

[Root@mysql test]# Zip test3.zip tests/*-x Tests/ln.log

Command name: Unzip

Function Description: Extract zip file

Syntax: Unzip [-cflptuvz][-agcjlmnoqsvx][-p < password >][.zip file] [file][-d < directory >][-x < file] or unzip [-z]

Supplemental Note: Unzip is the decompression program for the. zip compressed file.

Parameters

-C Displays the uncompressed results to the screen and converts the characters appropriately.

-F to update existing files.

-L Displays the files contained within the compressed file.

-P, similar to the-c parameter, displays the uncompressed results to the screen, but does not perform any transformations.

-T check that the compressed file is correct. , but puzzled pressure.

-U is similar to the-f parameter, but in addition to updating an existing file, the other files in the compressed file are uncompressed to the directory.

-V displays detailed information when it is executed. or view the compressed file directory, but do not understand the pressure.

-Z Displays only the memo text for the compressed file.

-A makes the necessary character conversions to the text file.

-B Do not convert text files to characters.

The file name in the-C compressed file is case-sensitive.

-J does not handle the directory path in the compressed file.

-L Change all file names in the compressed file to lowercase.

-M sends output to more program processing.

-N uncompressed does not overwrite the original file.

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

-p< Password > Use zip password option.

-Q does not display any information at execution time.

-S converts the whitespace character in the file name to the bottom line character.

-V preserves file version information for VMS.

-X to save the original uid/gid of the file while decompressing.

[. zip file] Specifies a. zip compressed file.

[file] Specifies which files in the. zip compressed file to process.

-d< directory > Specifies the directory to store after the file is uncompressed.

-x< file > Specify which files in the. zip compressed file should not be processed.

-Z unzip-z is equal to executing zipinfo directives.

Example 1: Unzip the compressed file Text.zip under the current directory.

[Root@mysql test]# Unzip Test.zip

Example 2: Text.zip the compressed file in the specified directory/TMP, and if the same file exists, requires that the unzip command not overwrite the original file.

 [Root@mysql test]# unzip-n test.zip-d/tmp

Example 3: View the compressed file directory, but do not understand the pressure.

 [Root@mysql test]# unzip-v Test.zip

Example 4: Extract the Compressed file (Test.zip) under the specified directory TMP, and if the same file exists, require the unzip command to overwrite the original file.

[Root@mysql test]# unzip-o test.zip-d tmp/

Use

Unzip "*.zip"

ls *.zip | xargs-n1 unzip

Unzip all zip files in the current directory
