If there are any files in the current directory whose names consist of a 
single letter, then one or both of [a-z] and [A-Z] (depending on LC_COLLATE)
will be expanded by the shell and the tr command will not receive the 
arguments you intended. Try quoting the arguments like this:
	tr '[a-z]' '[A-Z]'
