Generally commands that fail do so silently. Like the following that creates a directory twice. The first time actually creates the directory but the second command with the same directory name fails automatically because the directory already exists.
` Make a directory
make directory "MyTest"
` Make the same directory
make directory "MyTest"
print "Directory made."

The rest of the commands MrValentine mentioned are listed under the File Commands in the help files.
