DOS Commands

You will need to know how to make your way around in a DOS command environment. Useful sites that may be useful to read before/during the exercises are:

• List of DOS commands

Especially these:

dir	Shows the contents of the current directory (folder)
mkdir name	Makes a new directory called name
cd name	Enters the directory called name
cd ..	Goes up and out of the current directory
copy source target	Makes a copy of source with the name target, or makes a copy of source with the same name inside a directory called target (if present)
move source target	Moves source inside a directory called target (if present)
rename oldname newname	Renames oldname to newname
del name	Deletes the file called name (be careful!)
cls	Clears the console/terminal
echo %PATH%	Shows the list of places where the system looks for programs
Ctrl+C (holding down Ctrl and C)	Terminate a program - useful if you have accidentally programmed an infinite loop that you want to stop
