Unix -- a bunch of flavors and a lot of history.

Everyone knows

     [ -e foo ]

but who knows that it may not be available to you?  On SunOS  5.9
the man page test(1) reads:

     -e file
     True if file exists. (Not available in sh.)

This result in:

     /bin/sh -c 'test -e foo'
     /bin/sh: test: argument expected

Thus, beware!
