文件打包命令,把一组文件或目录打到一个文件里。还可以选择是否压缩、哪种压缩。或者反之把它打包的文档还原并拆成一个一个的文档。

tar
-c: 建立压缩档案
-x:解压
-t:查看内容
-r:向压缩归档文件末尾追加文件
-u:更新原压缩包中的文件

这五个是独立的命令,压缩解压都要用到其中一个,可以和别的命令连用但只能用其中一个。下面的参数是根据需要在压缩或解压档案时可选的。

-z:有gzip属性的
-j:有bz2属性的
-Z:有compress属性的
-v:显示所有过程
-O:将文件解开到标准输出

下面的参数-f是必须的

-f: 使用档案名字,切记,这个参数是最后一个参数,后面只能接档案名。

# tar -cf all.tar *.jpg 
这条命令是将所有.jpg的文件打成一个名为all.tar的包。-c是表示产生新的包,-f指定包的文件名。 

# tar -rf all.tar *.gif 
这条命令是将所有.gif的文件增加到all.tar的包里面去。-r是表示增加文件的意思。 

# tar -uf all.tar logo.gif 
这条命令是更新原来tar包all.tar中logo.gif文件,-u是表示更新文件的意思。 

# tar -tf all.tar 
这条命令是列出all.tar包中所有文件,-t是列出文件的意思 

# tar -xf all.tar 
这条命令是解出all.tar包中所有文件,-x是解开的意思 

压缩
tar –cvf jpg.tar *.jpg //将目录里所有jpg文件打包成tar.jpg
tar –czf jpg.tar.gz *.jpg   //将目录里所有jpg文件打包成jpg.tar后,并且将其用gzip压缩,生成一个gzip压缩过的包,命名为jpg.tar.gz
tar –cjf jpg.tar.bz2 *.jpg //将目录里所有jpg文件打包成jpg.tar后,并且将其用bzip2压缩,生成一个bzip2压缩过的包,命名为jpg.tar.bz2
tar –cZf jpg.tar.Z *.jpg   //将目录里所有jpg文件打包成jpg.tar后,并且将其用compress压缩,生成一个umcompress压缩过的包,命名为jpg.tar.Z
rar a jpg.rar *.jpg //rar格式的压缩,需要先下载rar for linux
zip jpg.zip *.jpg //zip格式的压缩,需要先下载zip for linux

解压
tar –xvf file.tar //解压 tar包
tar -xzvf file.tar.gz //解压tar.gz
tar -xjvf file.tar.bz2   //解压 tar.bz2
tar –xZvf file.tar.Z   //解压tar.Z
unrar e file.rar //解压rar
unzip file.zip //解压zip

总结
1、*.tar 用 tar –xvf 解压
2、*.gz 用 gzip -d或者gunzip 解压
3、*.tar.gz和*.tgz 用 tar –xzf 解压
4、*.bz2 用 bzip2 -d或者用bunzip2 解压
5、*.tar.bz2用tar –xjf 解压
6、*.Z 用 uncompress 解压
7、*.tar.Z 用tar –xZf 解压
8、*.rar 用 unrar e解压
9、*.zip 用 unzip 解压

 

 

帮助

tar --help

  1 Usage: tar [OPTION...] [FILE]...
  2 GNU `tar' saves many files together into a single tape or disk archive, and can
  3 restore individual files from the archive.
  4 
  5 Examples:
  6   tar -cf archive.tar foo bar  # Create archive.tar from files foo and bar.
  7   tar -tvf archive.tar         # List all files in archive.tar verbosely.
  8   tar -xf archive.tar          # Extract all files from archive.tar.
  9 
 10  Main operation mode:
 11 
 12   -A, --catenate, --concatenate   append tar files to an archive
 13   -c, --create               create a new archive
 14   -d, --diff, --compare      find differences between archive and file system
 15       --delete               delete from the archive (not on mag tapes!)
 16   -r, --append               append files to the end of an archive
 17   -t, --list                 list the contents of an archive
 18       --test-label           test the archive volume label and exit
 19   -u, --update               only append files newer than copy in archive
 20   -x, --extract, --get       extract files from an archive
 21 
 22  Operation modifiers:
 23 
 24       --check-device         check device numbers when creating incremental
 25                              archives (default)

 27   -G, --incremental          handle old GNU-format incremental backup
 28       --ignore-failed-read   do not exit with nonzero on unreadable files
 29       --level=NUMBER         dump level for created listed-incremental archive
 30   -n, --seek                 archive is seekable
 31       --no-check-device      do not check device numbers when creating
 32                              incremental archives
 33       --no-seek              archive is not seekable
 34       --occurrence[=NUMBER]  process only the NUMBERth occurrence of each file
 35                              in the archive; this option is valid only in
 36                              conjunction with one of the subcommands --delete,
 37                              --diff, --extract or --list and when a list of
 38                              files is given either on the command line or via
 39                              the -T option; NUMBER defaults to 1

  5 NAME
  6        tar - manual page for tar 1.26
  7 
  8 SYNOPSIS
  9        tar [OPTION...] [FILE]...
 10 
 11 DESCRIPTION
 12        GNU `tar' saves many files together into a single tape or disk archive, and can restore individual files from the archive.
 13 
 14        Note  that  this manual page contains just very brief description (or more like a list of possible functionality) originally generated by the help2man utility.  The full documenta‐
 15        tion for tar is maintained as a Texinfo manual.  If the info and tar programs are properly installed at your site, the command `info tar' should give you  access  to  the  complete
 16        manual.
 17 
 18 EXAMPLES
 19        tar -cf archive.tar foo bar
 20               # Create archive.tar from files foo and bar.
 21 
 22        tar -tvf archive.tar
 23               # List all files in archive.tar verbosely.
 24 
 25        tar -xf archive.tar
 26               # Extract all files from archive.tar.
