I think the carriage return at the end of the input is scrolling up the terminal. How about prompting for a single Y or N response (no need to CR):
Code:
#!/bin/bash
# -----
# function: askYesOrNo
# purpose : ask question passed as $1
# return : 0 if answer was y or Y,
# 1 otherwise
# -----
function askYesOrNo {
printf "\e[s" # save cursor x-pos
while true ; do
printf "\e[1;31;47m$1 [Y|n]\e[0m " # print $1 in color
read -n 1 answer
case $answer in
Y|y|N|n) break;;
esac
# restore cursor x-pos
printf "\e[u"
done
# restore cursor x-pos, erase rest of line
printf "\e[u\e[K"
# set return status
[ "${answer^}" == "Y" ]
}
for (( i = 100, max = 110; i <= max; i++ )) ; do
printf " %d\n" $i
if [ $i -eq $max ] ; then
if askYesOrNo "Do you wish to continue?" ; then
(( max += 10 ))
fi
fi
done
Yes, read -n 1 - I did that and it works but I wanted to have it my way.
I want to get the screen width and cursor positions.
When I used curses, all the screen content was cleared.
So Can I use curses to get the screen size without clearing anything in the window?
Or is there any other alternative???
I can use only C or C++. (0 Replies)

I need to get the cursor position, and put it inside a variable. Problem is, i don't have the tput command, or ncurses.
Apparently I was supposed to try the following:
echo -e '\E
But I don't get a value or anything. Please help. (3 Replies)
Hi there.
It's easier to explain this with a pseudo code, I hope this makes sense:
var1=hello
echo $var1
some kind of loop
echo loop counter

How do I hold the cursor position immediately behind the last output so I'd get something like:

DESCRIPTION
This function moves the result set cursor to the specified field offset. This offset is used by cubrid_fetch_field(3) if it doesn't
include a field offset. It returns TRUE on success or FALSE on failure.
PARAMETERS
o $result
-$result comes from a call to cubrid_execute(3)
o $field_offset

issued.
RETURN VALUES
TRUE on success.
FALSE on failure.
EXAMPLES
Example #1
cubrid_field_seek(3) example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$req = cubrid_execute($conn, "SELECT event_code,athlete_code,nation_code,game_date FROM game WHERE host_year=1988 and event_code=20001;");
var_dump(cubrid_fetch_row($req));
cubrid_field_seek($req, 1);
$field = cubrid_fetch_field($req);
printf("

");
printf("%-30s %s
", "name:", $field->name);
printf("%-30s %s
", "table:", $field->table);
printf("%-30s "%s"
", "default value:", $field->def);
printf("%-30s %d
", "max length:", $field->max_length);

printf("%-30s %d
", "numeric:", $field->numeric);
printf("%-30s %s
", "type:", $field->type);
cubrid_close_request($req);
cubrid_disconnect($conn);
?>
