Linux Learning Notes (iv) Archiving and compression

one, zip compression command:

1. Compress files:

Format: Zip compressed file source file

Example: Zip abc.zip ABC//compress the ABC file into the Abc.zip file.

2. Compression directory:

Format: Zip–r compressed directory source directory

Example: Zip dir.zip dir//The Dir directory is compressed into a dir.zip file.

3. Unzip the file:

To extract a command using the unzip:

Format: Unzip compressed file

Example: Unzip Abc.zip//shrinks the Abc.zip file. (Files and directories use the same decompression command)

Ii.. gz format Compression

1. Compress files

Format: gzip source file

Example: gzip abc.txt

Note: The source file disappears when you use the gzip compressed file

2. Compressed files do not delete source files

Format: gzip–c source files > Compressed files

Example: Gzip-c abc.txt > abc.gz//Compress source files into abc.gz format.

3. Compress all sub-files in the directory

Format: Gzip–r Directory

Example: GZIP–R/JP//Compress all sub-files in the JP directory, the source files in the directory disappear.

4. Unzip the file

Format: Gzip–d Compressed file

Example: Gzeip–d abc.gz

Or:

Format: Gunzip compressed file

Example: Gunzip abc.gz

Example: Gunzip–r JP//Unzip all sub-files in the directory:

Iii.. bz2 format Compression

1. Compress files

Format: bzip2 source file

Example: bzip2 abc.txt//Compressed Abc.txt file, do not retain the original file.

Example: bzip2 a.txt b.txt//colleague compresses a.txt and b.txt files without preserving the source files.

2. Keep source file compression

Format: bzip2–k source file

Example: Bzip2–k abc.txt//compress abc.txt file, keep source file

3. Decompression

1, Bzip2 Way

Format: Bzip2–d Compressed file

Example: Bzip2–d abc.bz2//decompression does not preserve source files

Example: BZIP2–DK abc.bz2//extract retention source files

2, Bunzip2 Way

Format: Bunzip2 Compressed file

Example: BUNZIP2 abc.bz2//decompression does not preserve source files

Example: Bunzip2–k abc.bz2//extract retention source files

Iv. Tar packaging commands

1. Packing

Format: TAR–CVF package file name source file

Options:

-Z: Compress files in tar.gz format

-j: Compressing files in tar.bz2 format

-C: Packaging

-V: Display procedure

-F: Specifies the file name after packaging

Example: TAR–CVF jp.tar JP//The JP directory is packaged as a Jp.tar format file.

Example: TAR–ZCVF jp.tar.gz JP//package and compress the JP directory

Example: TAR–JCVF jp.tar.bz2 JP//package and compress the JP directory

Example: tar–jcvf/tmp/jp.tar.bz2 jp1 JP2//Packaging compressed multiple folders to a specified directory

2. Unpacking

Format: TAR–XVF package file name

Options:

-Z: Unzip. GZ formatted files

-j: Compressing files in tar.bz2 format

-X: Unpacking

-T: View file contents

Example: TAR–XVF Jp.tar//Unpacking the Jp.tar

Example: TAR–ZXVF jp.tar.gz//Unpacking the jp.tar.gz

Example: TAR–JXVF jp.tar.bz2//Unpacking the JP.TAR.BZ2

Example: TAR–JXVF jp.tar.bz2-c/tmp//extract jp.tar.bz2 to the specified directory

Example: TAR–JTVF jp.tar.bz2//view contents in a compressed package
