Oops. I did test with -e on Solaris though $ Version M-11/16/88i $ ksh -ec '((0)); echo X' X $ /usr/xpg4/bin/sh -ec '((0)); echo X' X (That sh being a slightly modified version of ksh88i to address POSIX compliance IIRC). Possibly HP-UX changed it? Sounds more likely than Solaris changing it the other way round. What version of ksh is it based on? -- Stephane
