So I have a pretty good feeling that inserting -n's into the rsh calls in dejagnu that don't redirect stdin is indeed a good idea.Can you determine how portable `-n' is? Got any SunOS, Ultrix or old HP-UX boxes? :-)
http://www.FreeBSD.org/cgi/man.cgi says it's in every version of SunOS, Ultrix, and Dec OSF/1 it lists. http://www.docs.hp.com/cgi-bin/otsearch/getfile?top=/hpux/onlinedocs/B2355-90128/B2355-90128_top.html&id=/hpux/onlinedocs/B2355-90128/00/02/283-con.html&searchterms=rsh says that remsh takes the -n flag in HP/UX 10 (and up, presumably). I'd say it's probably safe... alternately, perhaps you could redirect stdin to /dev/null yourself... - Dan
