This actually depends on what version of ksh you're using.
The -e operand (which is now POSIX) wasn't available in older versions
of ksh88.

On some versions of HP-UX the ksh provided as /usr/bin/ksh is actually an older version than the system sh, provided as /usr/bin/sh, which is actually a newer version of the Korn Shell.

Consider the following:

$ uname -sr
HP-UX B.11.11
$ /usr/bin/ksh -c '[ -e .profile ]; what /usr/bin/ksh|fgrep Ver'
/usr/bin/ksh: test: argument expected
        Version 11/16/88
$ /usr/bin/sh -c '[ -e .profile ];what /usr/bin/sh|fgrep Ver'
         Version M-11/16/88f

So in order to run your script you could simply switch from ksh to sh.

sounds like you are using ksh88 rather than ksh93.

even pdksh appears to support -e.
