Filenames
Filenames can be up to 256 characters long.
You can use any characters you like in a filename, except for the following
metacharacters, which have a special meaning to the shell:
! ? * " ' ` ; / $ < > ( ) | { } [ ]
It is a good idea to choose meaningful filenames to make it easier to remember what the files contain.
