Used to compress and decompress files. tar itself does not have compression, packing only a function of compressing and decompressing is related to call other functions to complete.

Clarify two concepts: packing and compression. Packaging refers to a lot of files or directories into a general file; a large file compression sucked into a small file with some compression algorithms

Common parameters:

-c 建立新的压缩文件              （建立压缩档案） 
-f 指定压缩文件          
-r 添加文件到已经压缩文件包中     （向压缩归档文件末尾追加文件）
-u 添加改了和现有的文件到压缩包中 （向压缩归档文件末尾追加文件）
-x 解压文件  
-t 显示压缩文件中的内容           （查看内容）
-z 支持gzip压缩
-j 支持bzip2压缩
-Z 支持compress解压文件
-v 显示操作过程                  （显示所有过程）

About gzip and bzip2 compression:

gzip 实例：压缩 gzip fileName .tar.gz 和.tgz  解压：gunzip filename.gz 或 gzip -d filename.gz
          对应：tar zcvf filename.tar.gz     tar zxvf filename.tar.gz

bz2实例：压缩 bzip2 -z filename .tar.bz2 解压：bunzip filename.bz2或bzip -d filename.bz2
       对应：tar jcvf filename.tar.gz         解压：tar jxvf filename.tar.bz2

Example:

(1) All files packaged into a tar package

tar -cvf log.tar 1.log,2.log 或tar -cvf log.*

(2) the current directory all packaged into a txt file txt.tar

tar -cvf txt.tar *.txt     

(3) the current directory of all packaged into txt file txt.tar, and which was gzip compression, to generate a gzip compressed package named txt.tar.gz 

tar -zcvf  txt.tar.gz  *.txt

(4) packaged into a txt file directory all txt.tar, and compressed with bzip2 which generates a bzip2 compressed package named txt.tar.bz2

tar -jcvf  txt.tar.bz2  *.txt

(5) all files and directories under / etc package to the specified directory, and use the gz compression

tar -zcvf /tmp/etc.tar.gz /etc

(6) view the contents of the file you just packaged (plus some z, because it is compressed with gzip)

tar -ztvf /tmp/etc.tar.gz

(7) to compress pack / home, / etc, but do not / home / dmtsai

tar --exclude /home/dmtsai -zcvf myfile.tar.gz /home/* /etc

 (8) After all packaged txt files into directory txt.tar, compress and which was compressed to generate a compressed umcompress package named txt.tar.Z

tar -Zcvf  txt.tar.Z  *.txt

(9) to the current directory packet decompression txt.tar

tar -xvf  txt.tar

(10) to extract the packet txt.tar / home directory

tar -xvf  txt.tar -C /home

(11) unzip the package to the current directory txt.tar.gz

tar -zxvf  txt.tar.gz

(12) to the current directory packet decompression txt.tar.bz2

tar -jxvf  txt.tar.bz2

(13) to the current directory packet decompression txt.tar.Z

tar -Zxvf  txt.tar.Z
