tar是一个打包工具，但是其有选项可以直接将这个“包”进行压缩，与gunzip类似。

命令总览：

tar cf myproject.tar myprojecttar xf myproject.tartar cvf myproject.tar myprojecttar xvf myproject.tartar zcf myproject.tar myprojecttar zxf myproject.tartar zcvf myproject.tar.gz myproject --exclude myproject/log(注意-- exclude myproject/log后没有/）

z指定与压缩有关；f指定文件；v是verbose，详细输出；x和c互斥，x是解包，c是打包…

打包要有c/x以及f即可，压缩就多带着z即可。

PS：其实我一般都不加v选项，刷屏的感觉…

我在工作中通常有这么一种情况：

现网的相关项目我需要把它取下来，但是由于现网业务很多，长时间未清理日志，所以在log目录下文件占用很大（可能有几十个G），So：

如何打包其他的目录而不包含某个目录？

[test1280@localhost 20170702]$ tar zcvf myproject.tar.gz myproject --exclude myproject/logmyproject/myproject/etc/myproject/etc/etcfilemyproject/lib/myproject/lib/libfilemyproject/src/myproject/src/srcfilemyproject/bin/myproject/bin/binfile[test1280@localhost 20170702]$ ll总计 8drwxrwxr-x 7 test1280 test1280 4096 07-02 09:33 myproject-rw-rw-r-- 1 test1280 test1280  254 07-02 09:50 myproject.tar.gz

从v选项的verbose中可以看出确实没有将log目录打包压缩进myproject.tar.gz。

[test1280@localhost 20170702]$ tar zxvf myproject.tar.gz myproject/myproject/etc/myproject/etc/etcfilemyproject/lib/myproject/lib/libfilemyproject/src/myproject/src/srcfilemyproject/bin/myproject/bin/binfile[test1280@localhost 20170702]$ ll总计 8drwxrwxr-x 6 test1280 test1280 4096 07-02 09:33 myproject-rw-rw-r-- 1 test1280 test1280  254 07-02 09:50 myproject.tar.gz[test1280@localhost 20170702]$ tree myprojectmyproject|-- bin|   `-- binfile|-- etc|   `-- etcfile|-- lib|   `-- libfile`-- src    `-- srcfile4 directories, 4 files

进一步证明：没有将log目录加进去。

如何exclude多个目录？

[test1280@localhost 20170702]$ tar zcvf myproject.tar.gz myproject --exclude myproject/log --exclude myproject/libmyproject/myproject/etc/myproject/etc/etcfilemyproject/src/myproject/src/srcfilemyproject/bin/myproject/bin/binfile

使用多次–exclude即可。

还有重要的一点需要说明：

tar zcvf myproject.tar.gz myproject --exclude myproject/logtar zcvf myproject.tar.gz myproject --exclude myproject/log/

两句话是不一样的，你可以试一下。

第一句可以达到我们想要的效果，第二句多了一个/，但是并没有真的exclude掉，还是在的，实际使用中注意下这点。
