On Solaris, the path would be /proc/$$/object/a.out.  From the code, I
think that'll work as far back as Solaris 2.6, but I don't have any old
machines to verify that on.

Solaris also has a "getexecname()" library call, also introduced in 2.6,
but that would require writing C code, and making it available from shell
code, which seems like it's more work (if slightly more stable an
interface).  There also are ways to get this information on Solaris with
dlinfo(), which may be more portable on other systems than getexecname().

has more, if you hadn't already gone looking.
