Replying to my own post... I figured it out...something that I have
never seen before.
this would work...
initlog $INITLOG_ARGS -c \
"su ${display##*:} -c \"cd ~${display##*:} && [ -f
.vnc/passwd ] && vncserver :${display%%:*} $ARGS\""
# "su ${display##*:} -c \"cd ~${display##*:} && [ -f
.vnc/passwd ] && vncserver :${display%%:*}\""
but this wouldn't...
initlog $INITLOG_ARGS -c \
# "su ${display##*:} -c \"cd ~${display##*:} && [ -f
.vnc/passwd ] && vncserver :${display%%:*} $ARGS\""
"su ${display##*:} -c \"cd ~${display##*:} && [ -f
.vnc/passwd ] && vncserver :${display%%:*} $ARGS\""
Apparently you can't have comments within the continuation line of the
line before my problem...sheesh - all this time and energy because I
wanted to play it safe.
