cd black-tool then gedit install.sh change your line 12 to this "if" only :) but you will encounter another syntax :( idk what to do but I am still researching :) 👍

I had the same issue
to fix the error, here's what you should do
run this command stackoverflow
sed $'s/\r$//' ./install.sh > ./install.Unix.sh

sudo bash install.Unix.sh

if you face another syntax error here's what you should do

I'm using Linux so this fix will work only for linux

gedit install.Unix.sh

remove this function from the file
function windows_installing() { printf '\033]2;Black-Tool/Windows/Installing\a' clear print "Enter Path: " read path echo "Setup..." cd Black-Tool/Windows && cp hack.py $path echo " Black-Tool Installed " }

and remove this one two
function termux_installing() { printf '\033]2;Black-Tool/Termux/Installing\a' clear echo "Installing..." sleep 1 printf "Enter Path: " read path sleep 1 cd Black-Tool/Termux && cp hack $path echo " Black-Tool Installed! " }

and remove this one two
function choose_os() { clear echo "" echo " █▄▄ █░░ ▄▀█ █▀▀ █▄▀ ▄▄ ▀█▀ █▀█ █▀█ █░░ v4.0.0" echo " █▄█ █▄▄ █▀█ █▄▄ █░█ ░░ ░█░ █▄█ █▄█ █▄▄" echo "" echo " Choose OS: {1}.Linux {2}.Windows {3}.Android {99}.Exit " printf "choose/> " read choose if [[ "$choose" == '1']]; then try1 elif [[ "$choose" == '2']]; then windows_installing elif [[ "$choose" == '3']]; then termux_installing elif [[ "$choose" == '99']]; then clear echo " Exiting... " exit else choose_os fi }

save the file and run it as root sudo bash install.Unix.sh
