Analysis of the method of proficiently using the Linux system to query software package information
In the Linux system, the package manager is a very important tool, and the package manager can be used to conveniently Install, update, and uninstall software packages. However, in actual use, sometimes we need to query the detailed information of the software package, such as the version of the software package, installation path, dependencies, etc. This article will introduce how to query software package information in a Linux system through the command line, mainly involving apt
, yum
and dnf
package managers.
1. Use apt package manager to query software package information

yum info 软件包名称
For example, to query nginx
For detailed information about the software package, you can enter the following command:

rpm -ql 软件包名称
For example, to query gcc
For the installation path of the software package, you can enter the following command:
rpm -ql gcc
Through the above method, we can easily query the detailed information of the software package in the Linux system, helping us better understand and manage the software installed in the system Bag.
