Before installing Enterprise Management on Linux, verify that all required libraries are present on the target system.
The command uses the following syntax:
rpm -q --whatprovides capability
The command has the following parameters:
Specifies that you want to query RPM package information.
Specifies that you want to retrieve information which packages provide the capability.
Example: Verify that a library is installed
In this example, you want to verify that libcrypt.so.1 is installed. You receive a positive answer ($? is 0) and you learn that its is the glibc-2.5-42 package that provides libcrypt.so.1.
root> rpm -q --whatprovides libcrypt.so.1 glibc-2.5-42 root> echo $? 0
Example: Detect that a library is not installed
In this example, you want to find out whether libexample.so.1 is installed. You receive a negative answer ($? is 1), because no package is installed that provides this capability.
root> rpm -q --whatprovides libexample.so.1 no package provides libexample.so.1 root> echo $? 1
If a required library is missing, install it before proceeding the installation.
