A number of poster have responded to Ger's posting by suggesting the
-f option of test (builtin or separate executable).  Most claimed this
option tests if the file exists and suggest that the manual be read.

They should read the manual which says:

	-f file   true if file exists AND is a regular file

(emphasis mine)

I.e., the -f is a filetype/existance test.  If a directory foobar
exists, test -f foobar is false; test -d foobar is true.

There are a number of filetype/existance options to test:

	-f	regular files
	-d	directory files
	-b	block special files
	-c	character special files
	-p	named pipe files (fifo's)

and on some systems:

	-????	symbolic link files
