How to find installed software in Linux,

1. rpm

Note that rpm is case sensitive.

Query installed packages starting with mysql

Rpm-qa mysql *

Query installed mysql packages

Rpm-qa | grep mysql

 

The rpm method sometimes has all installed packages.

 

2. yum

List all conditions of a specified package

Yum list package

 

Yum list | grep installed

 

3. whereis

Sometimes you can find the path of the corresponding package by searching for files.

For example, whereis mysql

 

4. ps

You can find the path of the corresponding package by searching the process.

Ps-ef | grep mysql

 

 

 

Problem: if the software installed by source code cannot be found through the above method, the rpm and yum methods are only applicable to software installed by rpm and yum, because the software installed in these two ways can be identified by default when running the command system, and the software installed in the source code method can be identified by the system unless a soft connection is established or through the configuration file, otherwise, you cannot search by using the two methods, but you can search by using the ps analysis process.
