How do I check when RPM packages were installed on my machine?
Resolution: You can use the following command to display the install date and time of all the packages installed on your system:
rpm -qa --last
If you have a vague idea of the package name pipe (pipe is | key) the output of the above command through grep and use a substring that would be in the package name.
For example, to search for packages containing the substring kernel.
rpm -qa --last | grep kernel
(Returns the install date and time for all packages with kernel in their name, such as the kernel, kernel-utils, etc.) If you know the exact name for the package, you can modify the command and specify the package name. For example:
rpm -q --last filesystem
(Returns the install date and time of the filesystem package)
