AFAIK it doesn't. And there is libast which also provides a |wordexp()| function - however that requires first that libast is available in the system. My plan for |wordexp()| in OPenSolaris looks like this: 1. Rename Solaris ksh to /bin/oksh and adjust |libc::wordexp()| to use /bin/oksh. This is needed that people can _safely_ replace /bin/ksh with ksh93 for tesing. 2. Introduce ksh93 and all required libraries (e.g. libshell, libdll, libcmd and libast) 3. Figure out how to deal with |libc::wordexp()|, likely via using |libast::wordexp()| The idea behind the plan is to do a smooth transition without blowing up anything between the steps. ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz at nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;)
