1.) In a terminal when we make an alias for any command line,the life of that alias is as long as the terminal is open.
But can we explicitly undo the alias command? i.e undo the alias assigned to that command without closing the terminal.
Also when we do something like
We add the files to that directory wherein all the command are stored.How do we undo this? One way of doing it is by closing the terminal,whats the other way?
I'm new to Unix ,please help. Correct me if i'm wrong
