bash script to get current line and row not working

ive written the following script to print out the current line and row every time it changes aka every time i press up,down,left or right but the output is always the same: row:43:col:141 i believe this means top left of the screen where 0 0 would be bottom right, but im not too sure. heres my script: #!/bin/bash echo "press a key" tput clear row=$(tput lines) col=$(tput cols) while true; do echo "row:$row:col:$col" K1=,K2=,K3= read -s -N1 K1="$REPLY" read -s -N1 -t 0.001 K2="$REPLY" read -s -N1 -t 0.001 K3="$REPLY" key="$K1$K2$K3" case "$key" in $'\033[A') tput cuu 1;; $'\033[B') tput cud 1;; $'\033[C') tput cuf 1;; $'\033[D') tput cup $row $(($col-1));; *) echo "pressed a key!";; esac row=$(tput lines) col=$(tput cols) done exit 0 apparently theres no way to move the cursor left using tput, so I used: tput cup $row $(($col-1)) but this doesn't work either, any ideas how to fix?
