OK, I wrote a script that does near-enough what I wanted to do...
PHP Code:
#!/bin/bash
#Read time zones into array
i=1; for item in `cat timezones.txt`; do tz[$i]="$item"; let i=$i+1; done
i=1
echo "Locate timezone using up/down arrow keys then press enter to select."
while [ 0 ]; do
if [ $i -eq 0 ]; then i=1; fi
if [ ! ${tz[$i]} ]; then let i=i-1; fi
echo -en "\r "
echo -en "\r${tz[$i]}"
read -sn 1 twiddle
case "$twiddle" in
"B")
let i=i+1
;;
"A")
let i=i-1
;;
"")
echo
echo "OK to select ${tz[$i]} (y/N)?"
read -sn 1 confirm
if [ "$confirm" == "y" -o "$confirm" == "Y" ]; then
break
else
echo "Locate timezone using up/down arrow keys then press enter to select."
fi
;;
esac
done
echo
echo "Final choice was ${tz[$i]}"
The above script is fine for newer bash however CDLinux contains a really old version of bash that doesn't support the -en switches for the read command nor does it support arrays. After much faffing I managed to re-write the script to be backward compatible.
PHP Code:
#!/bin/bash
#Read time zones into array
function key_mode() {
if [ $1 -a $1 = "on" ]; then
stty_state=`stty -g`
stty raw; stty -echo
else
stty "$stty_state"
fi
}
i=1; for item in `cat timezones.txt`; do eval tz$i="$item"; let i=$i+1; done
i=1
echo "Locate timezone using up/down arrow keys then press enter to select."
key_mode on
while [ 0 ]; do
eval selection=$tz$i
if [ $i -eq 0 ]; then
i=1
eval selection=$tz$i
fi
if [ ${#selection} -lt 2 ]; then
let i=i-1
eval selection=$tz$i
fi
echo -en "\r "
echo -en "\r$selection"
twiddle=`dd bs=1 count=1 2>/dev/null`
#read -sn 1 twiddle
case "$twiddle" in
`echo -e "\102"`)
let i=i+1
;;
`echo -e "\101"`)
let i=i-1
;;
`echo -e "\015"`)
key_mode off
echo
echo "OK to select $selection (y/N)?"
key_mode on
confirm=`dd bs=1 count=1 2>/dev/null`
if [ "$confirm" = "y" -o "$confirm" = "Y" ]; then
break
else
key_mode off
echo "Locate timezone using up/down arrow keys then press enter to select."
key_mode on
fi
;;
esac
done
key_mode off
echo
echo "Final choice was $selection"
