-c: create compressed files

-x: decompression

-t: view content

-r: appends files to the end of the compressed archive file

-z: with gzip attribute

-j: with bz2 attribute

-Z: with compress attribute

The following parameter-f is required

-f: use the file name. Remember that this parameter is the last parameter and can only be followed by the file name.

-rw-r--r-- 1 svnuser svnuser 61440 Apr 21 09:39 a.tar

Compound compression command

Tar-cf a.tar * .txt / / package all jpg files in the directory into tar

Tar-czf b.tar.gz * .txt / / after all the jpg files in the directory are packaged into tar and compressed with gzip, a gzip compressed package is generated that ends with tar.gz.

Tar-cjf c.tar.bz2 * .txt / / package all the txt files in the directory into tar and compress them with bzip2 to generate a bzip2 compressed package that ends with tar.bz2

Tar-cZf d.tar.Z * .txt / / package all the txt files in the directory into tar and compress them with compress to generate a umcompress compressed package that ends with tar.Z

Tar-czf f.tgz * .txt / / package all txt files in the directory as files at the end of tgz

Extract the tar compressed packet

# tar-xf a.tar / / decompress the compressed package at the end of tar

# tar-xzvf b.tar.gz / / decompress the compressed package at the end of tar.gz

# tar-xjvf c.tar.bz2 / / decompress the compressed package at the end of tar.bz2

# tar-xZvf d.tar.Z / / decompress the compressed package at the end of tar.Z
