RPM Application--queries (installed packages and not installed packages)

Query function

Command format rpm {-q|--query} [select-options] [query-options]

RPM Query function is extremely powerful, is one of the most important functions; For a few common examples, more detailed specific, please refer to #man rpm

1, the system has installed the software query

1 Query system installed software

Syntax: RPM-Q software name

Example: [Root@localhost beinan]# rpm-q Gaim

Gaim-1.3.0-1.fc4

View all installed packages in the system, plus a parameter;

[Root@localhost rpms]# Rpm-qa

If paging view, add a pipe | and more command;

[Root@localhost rpms]# Rpm-qa |more

Find a software in all installed packages, such as Gaim, which can be extracted using grep;

[Root@localhost rpms]# Rpm-qa |grep Gaim

The above function is the same as the result of rpm-q gaim output;

2 Find out which package is owned by a file that is already installed

Syntax RPM-QF file name

Note: The absolute path to the filename is indicated

Example:

[Root@localhost rpms]# rpm-qf/usr/lib/libacl.la

Libacl-devel-2.2.23-8

3 Find out where the installed packages are installed

Syntax: RPM-QL software name or rpm RPMQUERY-QL software name

Example:

[Root@localhost rpms]# RPM-QL Lynx

[Root@localhost rpms]# RPMQUERY-QL Lynx

4 Query The information of an installed package

Syntax format: RPM-QI software name

Example:

[Root@localhost rpms]# Rpm-qi Lynx

5 Check the configuration file of the installed software

Syntax format: RPM-QC software name

Example:

6 View a document installation location where the software has been installed

Syntax format: RPM-QD software name

Example:

[Root@localhost rpms]# RPM-QD Lynx

7 Check the software packages and files that are on the installation

Syntax format: RPM-QR software name

Example:

[Root@localhost beinan]# RPM-QR Rpm-python

A summary of the query installed software: For a package has been installed, we can combine a series of parameters, such as Rpm-qil, such as:

[Root@localhost rpms]# Rpm-qil Lynx

2, for the installation of the package is not installed view:

The prerequisite for viewing is that you have a. rpm file, that is, a view of the existing software file.rpm;

1) To view the use of a package, version and other information;

Syntax: Rpm-qpi file.rpm

Example:

[Root@localhost rpms]# Rpm-qpi lynx-2.8.5-23.i386.rpm

2 View the files contained in a package;

Syntax: RPM-QPL file.rpm

Example:

[Root@localhost rpms]# RPM-QPL lynx-2.8.5-23.i386.rpm

3 View the location of the package's documentation;

Syntax: RPM-QPD file.rpm

Example:

[Root@localhost rpms]# RPM-QPD lynx-2.8.5-23.i386.rpm

4 View the configuration file of a package;

Syntax: RPM-QPC file.rpm

Example:

[Root@localhost rpms]# rpm-qpc lynx-2.8.5-23.i386.rpm

5 View the dependencies of a package

Syntax: RPM-QPR file.rpm

Example:

[Root@localhost archives]# RPM-QPR yumex_0.42-3.0.fc4_noarch.rpm

/bin/bash

/usr/bin/python

Config (yumex) = 0.42-3.0.fc4
