stty help please

[hokky]

Hi guys,

Can you please help me modify my script, I know I'm pretty close but I need someone help to nail it

Here's my code :

readkey() {
    oldstty=`stty -g`
    stty -icanon -echo min 0 time 100
    dd bs=1 count=1 <&0 2>/dev/null
    stty $oldstty
}

process() {
    mychar=
    mystring=
    flag="true"

    echo "$START_INPUT\c"

    while true
    do
        mychar=$(readkey)

        if [[ -z $mychar ]];then
                break
        fi

        if [[ "$mychar" = "^?" ]];then
                if [[ ${#mystring} -gt 0 ]];then
                        tput cub1 ; echo " \c" ; tput cub1
                        mystring="${mystring%?}"
                fi
        elif [font color=red][[ "$mychar" == "^M" ]][/font];then
                flag="false"
                echo "flag $flag\c"
                break
        else
                echo "$mychar\c"
                mystring="$mystring"$mychar

        fi

    done

    echo $flag

    SEL=$mystring
    echo "$END_INPUT\c"

    if [[ "$flag" == "true" ]];then
        timeout
    fi

}

As you can see the red one, I'm trying to change the $flag value if enter is pressed.

But the fact is the $flag always true

Thanks guys

Sorry wrong tags,

Here's the red one:
<font color="red">[[ "$mychar" == "^M" ]]</font>

Hi

Abit tricky that red...

What shell you use ? A suppose it is [tt]ksh[/tt]. But if is [tt]bash[/tt], I would prefer the red part this way :

[[ "$mychar" == $'\0D' ]]

By the way, better give up and read TGML to find out that the correct code is [tt][ignore][red][/ignore][/tt] .. [tt][ignore][/red][/ignore][/tt] or [tt][ignore][/ignore][/tt] .. [tt][ignore][/ignore][/tt].

yes feherke,

It's ksh.

Your way doesn't work in ksh.

Thanks about your advice about tags, I thought it's HTML
