I stumbled over a forgotten script I once used before we had watch(1).
Somebody might find it amusing. The point of the ho/ce/cd dance
instead of cl was to avoid flicker.
------------------->
#!/bin/ksh
# home, clear to end of line, clear to end of display
for i in ho ce cd; do
eval "$i=\$(tput $i)"
done
tput clear
while true; do
print -R -n "$ho"
eval "$@" | while IFS= read line; do
print -R "$line$ce"
done
print -R -n "$cd"
sleep 30
done
