To apply patches on an OpenBSD system, you can use the syspatch command. The syspatch command is a utility that is used to apply security patches to the kernel and userland programs on an OpenBSD system.
Here's an example of how to use the syspatch command to apply patches on an OpenBSD system:
syspatch
This command will apply all the available security patches to the system.
You can also use the syspatch command to apply a specific patch. For example, to apply patch number 123, you can use the following command:
syspatch 123
Before applying the patches, the syspatch command will show you a list of patches that will be applied and ask for confirmation. You can choose to accept or reject the patches by pressing y or n, respectively.
