I will apologise in advance for being so ignorant"
will the command "uname -a" display the current version of OS?
What command would I use to list the current running process on a system - is it ps ie or something similar?
What command can I use to show the current file system usage?
Which commands do I use to change the ownership/groupID and permissions of a file?
Which command would you use to list the users on a mounted filesystem?
Thank you very much
