c++ - Linux怎么实现以安装软件的路径查找呢？

Question

要做一个升级的东东，需要知道某个软件安装到了哪里去，比如我在centos下安装了Sublime_Text这个软件，我现在不知道这个软件安装到哪了，我想用编程的方式找出他来. linux下没有windows下的注册表没办法把安装程序的信息记录下来，有木有做过这种linux软件升级的大大？ 求给点思路~~

Answer 1

rpm -ql software name View the directory where the software is installed

Answer 2

If it is a Linux system such as ubuntu/debian that uses dpkg package management software, use:

dpkg -l software name

If it is a Linux system such as centos/redhat that uses rpm package management software, use:

rpm -ql software name

The above command can list all the files (installation path) of a software package, but if you want to upgrade the software, you should use other commands provided by the package management software to upgrade instead of replacing any files yourself!
