The cd command is a fairly basic command, it is used to change directory from within the terminal, The following examples help illustrate this:
This command will take the user to the home directory, although the user must be in a directory where the home directory is visible.
You can also skip a head if you know the file path, for example:
Once in the home folder you can more quite quickly to the /serverScripts/ folder if you know the file path.
In order to go back a a directory we use '..' for example:
This will take us back to the myScripts directory, to go right the way back we just do the following:
This will take us right back to the home directory
I hope this gives you a good understanding of the cd command, its pretty easy really.
