7.3 rpm工具用法

[root@localhost Packages]# rpm -ivh zsh-5.0.2-25.el7.x86_64.rpm        
准备中...                          ################################# [100%]
正在升级/安装...
   1:zsh-5.0.2-25.el7                 ################################# [100%]

这个文件在当前路径，可以加 ./zsh-5.0.2-25.el7.x86_64.rpm，或者可以使用相对路径，不用加 ./
安装rpm包的时候，也会存在依赖包

[root@localhost Packages]# rpm -e zsh
[root@localhost Packages]# 

直接删除，不会有任何提示。(若是有提示，很有可能是出现什么错误了)

[root@localhost Packages]# rpm -qa    这里截取了前几行代码
trousers-0.3.13-1.el7.x86_64
filesystem-3.2-21.el7.x86_64
bind-license-9.9.4-37.el7.noarch
fxload-2002_04_11-16.el7.x86_64
nss-softokn-freebl-3.16.2.3-14.4.el7.x86_64
libthai-0.1.14-9.el7.x86_64

列出来的都是已经安装好的包，这些都可以直接卸载

[root@localhost Packages]# rpm -q ppp
ppp-2.4.5-33.el7.x86_64
[root@localhost Packages]# 

若是已经安装的包，会直接显示出来；
若是未安装的包，则会提示未安装软件包。

Summary     : A version of the VIM editor which includes recent enhancements
Description :
VIM (VIsual editor iMproved) is an updated and improved version of the
vi editor.  Vi was the first real screen-based editor for UNIX, and is
still very popular.  VIM improves on vi by adding new features:
multiple windows, multi-level undo, block highlighting and more.  The
vim-enhanced package contains a version of VIM with extra, recently
introduced features like Python and Perl interpreters.

Install the vim-enhanced package if you'd like to use a version of the
VIM editor which includes recently added enhancements like
interpreters for the Python and Perl scripting languages.  You'll also
need to install the vim-common package.
