Operating system: Linux: Installer: File: Check: How to view
information about .rpm packages? [query]
---
Before doing your installation, you can use the rpm program
to get information about currently present rpm packages.
---
You can do so by using the -q parameter
(where 'Q' means query)
---
---
To get information about all already installed rpm packages, use the
command:
rpm -qa
or to show it one screen at a time, use:
rpm -qa | more
---
This will show e.g.
bzip2-libs-1.0.2-8
glib-1.2.10-10
losetup-2.11y-9
shadow-utils-4.0.3.6
MAKEDEV-3.3.2-5
findutils-4.1.7-9
modutils-2.4.22-8
...
So possibly first do this to get this overview of the rpm which
are already there.
---
---
To check for the presence an already installed individual package, use
e.g. a wildcard like '*'.
e.g.
rpm -qa b*
will show all packages with a name starting with a 'b'.
---
---
You can also use 'grep' to check for packages, for example
the 'bison' package:
rpm -qa | grep bison
could show 'bison-1.35-6'
---
---
If you just want to know if a package is installed, type:
rpm -q <your package name>
e.g.
rpm -q bison
could show as a result
bison-1.35-6
This indicates the currently installed version (=1.35) and build (=6),
and also that it indeed is installed.
---
---
To get specific information about an already installed rpm package
itself, use the command:
rpm -qi <your package name>
---
e.g.
rpm -qi gawk3.1.1-9.rpm
---
will show e.g. the following screen:
