centos yum 完全卸载依赖

centos yum 完全卸载依赖

 

 you install a package with  yum install, say  pdftk, it will pull in a lot of dependencies:

Installed:
  pdftk.x86_64 0:1.44-10.fc18 Dependency Installed: bouncycastle.noarch 0:1.46-6.fc18 itext-core.noarch 0:2.1.7-14.fc18 libgcj.x86_64 0:4.7.2-8.fc18 bouncycastle-mail.noarch 0:1.46-6.fc18 java-1.5.0-gcj.x86_64 0:1.5.0.0-40.fc18 sinjdoc.x86_64 0:0.5-13.fc18 bouncycastle-tsp.noarch 0:1.46-5.fc18 java_cup.noarch 1:0.11a-10.fc18 itext.x86_64 0:2.1.7-14.fc18 javamail.noarch 0:1.4.3-12.fc18 Complete! 

yum remove pdftk will remove only that package and not all the dependencies.

But you can look at all the 'transactions' (install, remove etc.):

$ sudo yum history list pdftk
ID     | Command line             | Date and time | Action(s) | Altered ------------------------------------------------------------------------------- 88 | install pdftk | 2012-12-14 13:35 | Install | 11 

And then you can undo that transaction:

$ sudo yum history undo 88
Undoing transaction 88, from Fri Dec 14 13:35:34 2012
