Linux commands: Compression and decompression

Compression, decompression command, different algorithm, compression ratio will also be different

Compression format: GZ, bz2, XZ, zip, Z

==================================================

gzip:. GZ

Gzip/path/to/somefile: The original file is deleted when the compression is complete

-D:

-#:1-9, specify the compression ratio, default is 6;

g un Zip:

Gunzip/path/to/somefile.gz: The original file will be deleted when the decompression is complete

Zcat/path/to/somefile.gz: To view the contents of a text file without being pressed

==================================================

BZIP2:. bz2

Compression tool with a greater compression ratio than gzip, using a format approximation

Bzip2/path/to/somefile

-D

-#: 1-9, default is 6

-K: Keep the original file when compressing

bunzip2/path/to/somefile.bz2

Bzcat

==================================================

XZ:. XZ

Xz/path/to/somefile

-D

-#: 1-9, default is 6

-K: Keep the original file when compressing

Unxz

Xzdec

Xzcat

installation package download Link: xz-5.2.2.tar.bz2 (1165 KiB)

==================================================

Zip: Both archived and compressed tools

Zip Filename.zip FILE1 FILE2 ...: Do not delete the original file after compression

Unzipfilename.zip

Archive: Archiving, archiving by itself does not imply compression

XZ, bz2, GZ

==================================================

Tar: Archive tool,. Tar

-C: Create an archive file

-F File.tar: Archived files for operations

-X: Expand Archive

--xattrs: Preserves extended attribute information for files when archiving

-T: Do not expand the archive to directly see which files are archived

-ZCF: Archive and invoke gzip compression

-ZXF: Call gzip to unzip and expand Archive,-Z option to omit

-jcf:bzip2

-JXF:

-jcf:xz

-JXF:

==================================================

Cpio: Archive Tool
