Linux命令

本文主要是介绍Linux命令，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

安装软件包命令，参数指明了（ v 展示正在安装的文件信息  

1 #rpm -i example.rpm 安装 example.rpm 包；
2 #rpm -iv example.rpm 安装 example.rpm 包并在安装过程中显示正在安装的文件信息；
3 #rpm -ivh example.rpm 安装 example.rpm 包并在安装过程中显示正在安装的文件信息及安装进度
rpm -ivh your_package_name
 
如：rpm -ivh jdk-8u111-linux-x64.rpm

rpm 常用命令
1.安装一个包 （展示正在安装的文件信息以及安装进度）
# rpm -ivh 
 
2.升级一个包 
# rpm -Uvh 
 
3.卸载一个包 
# rpm -e 
 
4.安装参数 
--force 即使覆盖属于其它包的文件也强迫安装 
--nodeps 如果该RPM包的安装依赖其它包，即使其它包没装，也强迫安装。 
 
5.查询一个包是否被安装 
# rpm -q < rpm package name> 
 
6.得到被安装的包的信息 
# rpm -qi < rpm package name> 
 
7.列出该包中有哪些文件 
# rpm -ql < rpm package name> 
 
8.列出服务器上的一个文件属于哪一个RPM包 
#rpm -qf 
 
9.可综合好几个参数一起用 
# rpm -qil < rpm package name> 
 
10.列出所有被安装的rpm package 
# rpm -qa 
 
11.列出一个未被安装进系统的RPM包文件中包含有哪些文件？ 
# rpm -qilp < rpm package name>
 
12.解压RPM包
 
有时我们需要RPM包中的某个文件，如何解压RPM包呢？
 
RPM包括是使用cpio格式打包的，因此可以先转成cpio然后解压，如下所示：
 
rpm2cpio xxx.rpm | cpio -div
