I will replace the following line of the Perl script that causes problem with dash: open (WOSSNAME, "export -n EMBOSS_ACDCOMMANDLINE;wossname -alpha -auto|") || die "Cannot run wossname"; by the following line: open (WOSSNAME, "(unset EMBOSS_ACDCOMMANDLINE; wossname -alpha -auto)|") || die "Cannot run wossname"; This wossname command just prints to stdout a list of available commands from the EMBOSS software suite Have a nice day, -- Charles Plessy Tsurumi, Kanagawa, Japan -- To UNSUBSCRIBE, email to debian-mentors-requ...@lists.debian.org with a subject of "unsubscribe".
