I am a little confused. I believe the problem is with the "if [ ! -t 0 ]" statement. I tried to redirect the error message; however, it still appears in the email sent by CRON. I tried using this statement instead: if ( ! tty -s &> /dev/null ) and "if ( ! tty -s ) &> /dev/null"; however, they also produce an error message although the function does work correctly. Is this just something I should just ignore, or is there a way to stop the message from being sent in the CRON report?
For Bourne shell, classic /bin/sh, and related shells (zsh, ksh), you can use something like:
case $- in *i*) # do stuff for an interactive shell echo "interactive" ;; *) # not interactive echo "not interactive" ;; esac Regards, -- -Chuck _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
