A Practical Guide to Red HatВ® LinuxВ®: Fedoraв„ў Core and Red Hat Enterprise Linux (3rd Edition)

If the system is less responsive than normal, what is a good first step in figuring out where the problem is?

A process stores its PID in a file named process.pid. Write a command line that will terminate the process.

Working as root, you are planning to delete some files but want to make sure that the wildcard expression you will use is correct. Suggest two ways you could make sure that you deleted the correct files.

Create a cron file that will regularly perform the following backups:

1. Performs a level 0 backup once per month.

2. Performs a level 2 dump one day per week.

3. Performs a level 5 dump every day that neither a level 0 nor a level 2 dump is performed.

In the worst case, how many restores would you have to perform to recover a file that was dumped using the preceding schedule?
