It is a good idea to check the File System in Linux every once in a while what do you need to make sure of when doing this?

Answer 4

• Make sure the File systems aren’t mounted when checking the file system. This often means checking the File System upon bootup.
• Often this is done automatically after a certain number of reboots, however some systems don’t get rebooted very often in that case you would want to force the file system check by adding a file to the root
• To accomplish this you would use the command “ sudo touch /forcefsck”

Question 5

Another good system maintenance task to perform would be to clean up your log space and ensure you have enough space for your logs. What directory would you use to access to do this?
