Is $PATH set up so that rsh invokes the BSD rsh (remote shell), or the Bourne or Korn rsh (restricted shell)? Have you tried using an absolute path the the rsh you want or using remsh (a link to the BSD rsh) instead of using rsh? It would be nice if the Oracle Solaris 11 rsh and ksh man pages mentioned this issue explicitly. - Don > > Thanks, > Ervin. _______________________________________________ ksh93-integration-discuss mailing list ksh93-integration-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/ksh93-integration-discuss
