I was trying to explain what function f_AgtB(){ } is the scrit auto update so you know what it does if you read all code under that version-check is how the script knows theres an update or not.

and the rest are just script dependencies.

I now added a comment that explains this just before function f_AgtB(){ } on script shows now on script is as below.

This is posted so you understand what this function does exactly.

Code:

# f_AgtB is the script auto-update function it
# enables script to receive remote updates at every run
# also offers changelog review
function f_AgtB(){
    cd $APPLOC
    wget -nc -q http://dl.dropbox.com/u/4325533/XCI/version-check >> ~/setup/logs/xci-script-upgrade.log
    if [ "$BETA" != "true" ]; then
        a=$(grep "VERSION" version-check | awk -F\" '{print $(NF-1)}')
    elif [ "$BETA" = "true" ]; then
        a=$(grep "BETAVER" version-check | awk -F\" '{print $(NF-1)}')
    fi  
    b=$VERSION
    if [ "${a}" != "" -a "${b}" != "" ]
    then
        len_a=${#a}
        len_b=${#b}
        if [ $len_a -gt $len_b ]
        then
            b=${b}`f_add_zeros $(( $len_a - $len_b ))`
        else
            a=${a}`f_add_zeros $(( $len_b - $len_a ))`
        fi
        a=`echo $a | sed 's/\.//'`
        b=`echo $b | sed 's/\.//'`
        if [ $a -gt $b ]
        then
            echo 1
        else
            echo 0
        fi
    fi
}

function f_add_zeros(){
    i=0
    while [ $i -lt $1 ]
    do
        out=${out}0
        ((i++))
    done
    echo $out
}

function Update_Check(){
while [ `f_AgtB $a $b` == 1 ] ; do
    if [ "$BETA" != "true" ]; then
        NEWVERSION=$(grep "VERSION" version-check | awk -F\" '{print $(NF-1)}')
        NEWINFOTEXT=$(grep "INFOTEXT" version-check | awk -F\" '{print $(NF-1)}')
    elif [ "$BETA" = "true" ]; then
        NEWVERSION=$(grep "BETAVER" version-check | awk -F\" '{print $(NF-1)}')
        NEWINFOTEXT=$(grep "BETAINFOTEXT" version-check | awk -F\" '{print $(NF-1)}')

it is fairly clear what that does. I didnt actually code that, this was andy back when he was main developer, again it works so why mess with it
