Comment (by jdemeyer):
For shell script portability discussions, I often refer to the GNU
autoconf manual: [http://www.gnu.org/savannah-
checkouts/gnu/autoconf/manual/autoconf-2.68/html_node/Portable-Shell.html
#Portable-Shell].
Quoting from there:
> But occasionally you may find it necessary to check whether some
arbitrary file exists. To do so, use ‘test -f’ or ‘test -r’. Do not use
‘test -x’, because 4.3BSD does not have it. Do not use ‘test -e’ either,
because Solaris /bin/sh lacks it. To test for symbolic links on systems
that have them, use ‘test -h’ rather than ‘test -L’; either form conforms
to Posix 1003.1-2001, but older shells like Solaris 8 /bin/sh support only
-h.
