Linux compression and archiving

There are several ways to compress under Linux: gzip, bzip2, XZ, zip

Gzip

The compressed file ends in. GZ,

Only files can be compressed and directories cannot be compressed
Usage:

Gzip:/path/to/somefile is used to compress, the original file will be deleted when finished
-D Decompression
-#: 1-9 To specify compression ratio eg:-9
Gunzip/path/to/somefile used to decompress, delete the original compressed file when finished
Zcat ZipFile Viewing compressed file contents

BZIP2:

The compressed file ends with a. bz2

Only files can be compressed and directories cannot be compressed
A greater compression ratio than gzip, only files can be compressed, folders cannot be compressed
Same as GZIP usage
-K can retain the original file when compressing,
Bzcat ZipFile Viewing compressed file contents

Zip:

Can compress the directory

Usage:

Zip compressed file name to compress files 1, files to compress 2

Unzip the file name to unzip
Do not delete the original file

Archive operations under Linux use the TAR command

Archiving is to put several files in a file with a. tar suffix

Usage: TAR-CF filename.tar file1,file2 .... Used to archive files

TAR-XF Filename.tar do not expand the archive and directly view which files are archived

-C: Create an archive file
-F File.tar Generated archive file
-X Expand Archive file
--xattrs: Preserves extended attribute information for files when archiving
-T: Do not expand the archive to directly see which files are archived

Tar can call each of the compression command implementations to both archive and compress.
-ZCF: Archive and invoke gzip compression
-ZXF: Call gzip to unzip and expand the archive, the-Z option can be omitted because the tar command can identify the compression tool used by the archive file according to the file suffix name (previous-can be omitted)
Similarly:-JCF: Call bzip2 Archive
-JXF: Call bzip2 Extract
