Compression decompression of Linux

Common compression formats in Linux

. zip. gz. bz2. tar.gz tar.bz2

Zip

Compressed files in ZIP format and Windows Universal, can be compressed/decompressed across platforms

Compression: Zip compressed file name source file

Zip-r compressed file name source directory

Decompression: Unzip compressed file

Gz

Compression: gzip source file {Compressed file compressed to GZ format, the source file disappears after compression succeeds}

Gzip-c source File > Compressed file {compressed to. gz format, source file reserved}

Gzip-r Directory {All sub-files under compressed directory, but cannot compress directory}

Decompression: gzip-d Compressed file

Gunzip Compressed Files

bz2

BZ2 Cannot compress directory

Compression: bzip2 source file {does not keep source file}

Bzip2-k source file {Keep source file}

Uncompressed: bzip2-d compressed file {-K Reserved compressed file}

Bunzip2 compressed File {-K Reserved compressed file}

tar.gz

is actually packaging the source file into a tar package, and then compressing the tar package using GZ

Compression: Tar [options] Package file name source file

Option:-C Package

-V Display procedure

-f Specifies the file name after packaging

The above three options are to package a file or directory into a tar package

-Z Compressed compressed package to tar.gz format

For example: TAR-CVF Test.tar *.txt to package the TXT document in the current directory as a Test.tar

TAR-ZCVF test.tar.gz *.txt to compress the TXT document in the current directory into test.tar.gz

Unzip: tar [options] Package file name

Option:-X Unpack the package

-V Display procedure

-f Specifies the file name after packaging

-Z Decompression

-T displays only the contents of the compressed package, but does not

Example: TAR-XVF Test.tar extract the Test.tar package

TAR-ZXVF test.tar.gz to extract test.tar.gz

tar.bz2

The difference between tar.bz2 and tar.gz is that when compressing and decompressing, the option-Z becomes-J
