检查已安装的软件包，如果找不到，则安装 [英] Checking for installed packages and if not found install

问题描述

我需要检查是否已安装软件包，如果未安装，请安装它们.

I need to check for installed packages and if not installed install them.

RHEL，CentOS，Fedora的示例:

Example for RHEL, CentOS, Fedora:

rpm -qa | grep glibc-static
glibc-static-2.12-1.80.el6_3.5.i686

如何进行BASH支票?

How do I do a check in BASH?

我会做类似的事情吗?

if [ "$(rpm -qa | grep glibc-static)" != "" ] ; then

对于其他发行版，我需要使用什么? apt-get?

And what do I need to use for other distributions? apt-get?

推荐答案

尝试以下代码:

if ! rpm -qa | grep -qw glibc-static; then
    yum install glibc-static
fi

或更短:

rpm -qa | grep -qw glibc-static || yum install glibc-static
