A slight gain--tar command

First, basic usage

Parameters:

-C: Create a compressed file

-x: Unlock a compressed file

-T: View the files in the compressed package

Second, compression

Scene:

# Tree/var/www/var/www├──blog│├──index.php│├──update││└──a.txt│└──websource│└──blog.html├──c ms│├──index.php│├──update││└──b.txt│└──websource│└──home.html├──license.txt└──log└──2015 0429.log

1. Package directory blog, where there will be/var/www/* directory prefix in compressed file test1.tar.gz

# tar-zcvf/var/www/test1.tar.gz/var/www/blogtar:removing Leading '/' from member names/var/www/blog//var/www/blog/ index.php/var/www/blog/update//var/www/blog/update/a.txt/var/www/blog/websource//var/www/blog/websource/ Blog.html

2. Remove the directory prefix

① into the blog directory, where the compressed file test2.tar.gz even the blog directory is also removed

# cd/var/www/blog# tar-zcvf/var/www/test2.tar.gz./././index.php./update/./update/a.txt./websource/./websource/ Blog.html

② into the upper directory of the blog directory/var/www

# cd/var/www# tar-zcvf/var/www/test3.tar.gz blogblog/blog/index.phpblog/update/blog/update/a.txtblog/websource/ Blog/websource/blog.html

Note: If you want to package both the blog directory and the CMS directory

# tar-zcvf/var/www/test4.tar.gz Blog cmsblog/blog/index.phpblog/update/blog/update/a.txtblog/websource/blog/ Websource/blog.htmlcms/cms/index.phpcms/update/cms/update/b.txtcms/websource/cms/websource/home.html

③ If you do not want to CD to the equivalent directory, add-c parameter,-C is a temporary switch working directory

# pwd/# Tar-zcvf/var/www/test5.tar.gz-c/var/www blogblog/blog/index.phpblog/update/blog/update/a.txtblog/ Websource/blog/websource/blog.html

# tar-zcvf/var/www/test6.tar.gz-c/var/www/blog./././index.php./update/./update/a.txt./websource/./websource/ Blog.html

3. Exclude certain directories or files when compressing a directory

TAR-ZCVF **.tar.gz--exclude=xx yy Note XX and yy is either a relative path at the same time, or it is an absolute path, otherwise it cannot exclude directories or files

E.g compress all files except CMS outside/var/www directory

① relative path

# cd/var# tar-zcvf/var/www/test7.tar.gz--exclude=www/cms www

② Absolute Path

# pwd/# tar-zcvf/var/www/test8.tar.gz--exclude=/var/www/cms/var/www

Note:/var/www/cms cannot be followed by A/

Third, decompression

From the second part of the compression experiment can be seen, command tar [OPTION ...] [FILE] ... where [FILE] defaults to the current directory

1. Extract to current directory

# pwd/# Tar-zxvf/var/www/test5.tar.gz

2. Unzip to the specified directory

# pwd/# Tar-zxvf/var/www/test5.tar.gz-c/Home

3. Unzip the specified directory or file in the compressed file

# Tar-zxvf/var/www/test4.tar.gz-c/Home blog# tar-zxvf/var/www/test4.tar.gz-c/Home blog/index.php
