See my first post above, i know that. The question is: why does "-e" work like it does and: is the POSIX documentation buggy there? According to the definition of "file" it should work like this:

if "file" exists and:
- is a regular file, "-f" will return TRUE
- is a block special file "-b" will return TRUE
- is a directory "-d" will return TRUE
...etc. analogously for "-c", "-h", "L", "-p", ...

and "-e" should return TRUE if any one of the above return TRUE.
