How to make Wait wait for completion?

Question

linux

test1.sh:

#!/bin/bash

echo test
sleep 5
echo test1
sleep 2

test.sh:

#!/bin/bash

password=`zenity --password`

echo ${password} | sudo -S gnome-terminal -e "./test1.sh"

for word in word1 word2 word3 word4
do
  echo $word
  sleep 1
done

How can I make the test.sh script wait for the gnome-terminal command to complete?
I tried wait in different options that I found on the Internet, but none of them help.
After calling the terminal, the script immediately enters the loop.

Answer 1

there is a simple
shell1.sh option

echo $$ >> /tmp/wait.pls
echo Process started
sleep 3
echo Process stopped
rm /temp/wait.pls

shell2.sh

password=`zenity --password`

echo ${password} | sudo -S gnome-terminal -e "./shell1.sh"

while true
do
  if [ ! -f /tmp/wait.pls ] ; then
    echo "Done"
    exit 0
  fi
done

Found an easier solution: xterm instead of gnome-terminal.
As it turned out, he does not jump to the next command.
Example:

#!/bin/bash

# Функция для запуска команды в xterm с определёнными настройками
# 1-й параметр либо команда либо ключ -s для запуска под root
# 2-й параметр либо пустой либо команда
x(){
  font_family=monospace
  font_size=10
  geometry=80x30
  font_color=lightgrey

  if ; then
    if ; then
      echo ${password} | sudo -S xterm -fa ${font_family} -fs ${font_size} -geometry ${geometry} -fg ${font_color} -e "$2;sleep 2"
    else
      echo "Нужен пароль!"
    fi
  else
    xterm -fa ${font_family} -fs ${font_size} -geometry ${geometry} -fg ${font_color} -e "$1;sleep 2"
  fi
}

# Функция проверки zenity диалогов с возможностью выхода
maybe_exit() {
  if ; then
    echo "Выход"
    exit $?
  fi
}

#sample
password=`zenity --password`
maybe_exit
x "./test1.sh"
x -s "apt update"
