Unix-legitimate filenames are any combination of these
three classes of characters: Upper and lower case letters:
A - Z and a - z

Numbers 0 - 9

Periods, underscores, hyphens . _ -

Note that line spaces (aka "whitespace") are not allowed in
filenames. The Unix shell will think you mean more than one
file.
