bash is supposed to be compatable with bourne. setting of environment variables is different. for c shell: setenv DISPLAY localhost:0 for bash: export DISPLAY=localhost:0 things like that. i would checkout the book and try some examples and see if they hold water. if they dont, try to foget what you learned. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
