The read-through rpm command is an administrative tool for RPM software packages. Rpm, originally a Red Hat Linux distribution program designed to manage Linux suites, is popular because it follows GPL rules and is powerful and convenient. Gradually adopted by other distributions. The emergence of RPM suite management makes Linux easy to install and upgrade, which indirectly improves the applicability of Linux. Install rpm-ivh package_name

(package_name refers to the file name of the RPM package)

Query

1. Query whether to install and install the version

Rpm-Q name of installed software (ex:rpm-Q docker-engine) rpm-qa | grep string (query the software version containing a string in all installed software)

two。 Query related configuration files

Rpm-ql software name (list the full file name where all files and directories of the software are located) rpm-qc software name (list all settings files of the software)

3. Query other software on which a software depends

Rpm-qR software name

4. Query which software package the file belongs to

Rpm-qf filename Uninstall rpm-e-- nodeps package_name verify the installed software name of rpm-V (list the configuration files that the software has been modified) rpm-Vf filename (list whether a file has been changed) fall back to the earlier version rpm-- Uvh-- oldpackage-- nodeps package_name

(this command includes two steps to uninstall the software package from the source environment and to install the earlier version of the package)

Backup tool rpmrebuild

Purpose: back up software that is already installed in the environment

Usage: rpmrebuild pacakge_name

If the relevant configuration of the software has been changed, the command asks whether to continue and whether to name a new software version name

If you do not need this query, you can use:

Rpmrebuild-b
