The cursor is in the wrong position, my mistake. I removed a couple of echo
lines to neaten the script before I emailed it, hence I messed up the tput
positioning.
The reverse video is correct, according to the tput man page this is bold
on/off, I guess in depends of the terminals capabilities.
The script I attached yesterday only ran under a bash shell.
As I had implicitly specified /bin/sh on line 1.
I have altered the script today to make it run under fish.
--------------Start ------------------------
#!/usr/bin/fish
if test "$OPSYSTEM" = "TANDEM";
set VIEWER "more"
else
set VIEWER "less"
end
set menu ""
while test "$menu" != "x";
tput clear
tput smso
echo 'Sample menu'
tput rmso
echo '1. Show disk space'
echo '2. Show uptime'
echo '3. Show /var/log/messages'
echo '4. Show /etc/hosts'
echo '5. Show network configuration'
echo 'x. Exit to shell'
echo ''
echo 'Select Option [1 - 5 or x to Return] :'
tput cup 8 38
read menu
tput clear
switch $menu
case 1
df -H
case 2
uptime
case 3
tail /var/log/messages
case 4
cat /etc/hosts | $VIEWER
case 5
ifconfig | $VIEWER
end
echo '** Press <ENTER> **'
set press ""
read press
end
--------------End ------------------------
Running the script seems to start an infinite loop, instead of stopping to
acquire the users input, the menu gets printed time after time.
I cannot tell if the tput cursor position line works correctly.
Have I got something wrong?

This works for me, except that the cursor is placed two lines below
the specified option. But that is as it should be, it is placed on
line 10 as per the tput command. Also, my terminal doesn't bold the
menu, it reverses the video, but smso only specifies 'standout mode'.
Is it the case that this does not work on your system when the command
is started from fish, but it does work when started from bash? If so,
try adding a 'reset' command at the top. If this helps, fish must
leave your terminal in a wonky state on startup.
