[SOLVED] how can I see if a package is installed or not?

[doktor5000]

Code: Select all

urpmq -i kernel-source-latest

shows for example lots of information aubout that package, but how can i figure out if it is already installed or not?

You could check in 'Install & remove software'.

[jkerr82508]

Code: Select all

rpm -qa | grep kernel-source

Will list any installed packages whose names include "kernel-source". If there are none it simply returns to the prompt.

As a general rule use urpmq to query the available packages in the repositories (both installed and not installed).
Use "rpm -q" to query the database of installed packages (which may or may not be in the repositories).

Thank you for the answer..Usually I need both and it would be nice to could do it in one go. (For example checking what is the mageia name of the readline package and is it installed.)

And I need a command-line or at least shell-based program to do this. On Debian based systems aptitude allows for regex searches and on RedHat based ones yum lists by case-insensitive wildcarded search strings. Both show immediately wether a package is already installed.

As a trade-off I'll put something like this in a function:

Code: Select all

urpmq -Y readline | tee >(grep --color=always -f - <(rpm -qa))
