tar 命令 详解

ar命令详解

-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

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

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.bz2tar –xZvf file.tar.Z //解压tar.Z

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

$ tar --help
Usage: tar [OPTION...] [FILE]...
GNU `tar' saves many files together into a single tape or disk archive, and can
restore individual files from the archive.

Examples:
  tar -cf archive.tar foo bar  # Create archive.tar from files foo and bar.
  tar -tvf archive.tar         # List all files in archive.tar verbosely.
  tar -xf archive.tar          # Extract all files from archive.tar.

 Main operation mode:

  -A, --catenate, --concatenate   append tar files to an archive
  -c, --create               create a new archive
  -d, --diff, --compare      find differences between archive and file system
      --delete               delete from the archive (not on mag tapes!)
  -r, --append               append files to the end of an archive
  -t, --list                 list the contents of an archive
      --test-label           test the archive volume label and exit
  -u, --update               only append files newer than copy in archive
  -x, --extract, --get       extract files from an archive

 Operation modifiers:

  -g, --listed-incremental=FILE   handle new GNU-format incremental backup
  -G, --incremental          handle old GNU-format incremental backup
      --ignore-failed-read   do not exit with nonzero on unreadable files
  -n, --seek                 archive is seekable
      --occurrence[=NUMBER]  process only the NUMBERth occurrence of each file
                             in the archive; this option is valid only in
                             conjunction with one of the subcommands --delete,
                             --diff, --extract or --list and when a list of
                             files is given either on the command line or via
                             the -T option; NUMBER defaults to 1
      --sparse-version=MAJOR[.MINOR]
                             set version of the sparse format to use (implies
                             --sparse)
  -S, --sparse               handle sparse files efficiently

                             times in the first place (METHOD='system')
      --delay-directory-restore   delay setting modification times and
                             permissions of extracted directories until the end
                             of extraction
      --group=NAME           force NAME as group for added files
      --mode=CHANGES         force (symbolic) mode CHANGES for added files
