Bash腳本。 打開新終端並運行命令

Question

如何從bash在新終端中運行命令？ 如果僅從一個終端運行，則mosquitto_sub阻止腳本。 xterm -e打開新終端，但我的腳本也被阻止...

 #!/bin/bash 
         COUNTER=0
     xterm -e mosquitto_sub -h 192.168.1.103 -t test
     mosquitto_pub -h 192.168.1.103 -t test -m "Connected"
     cd Desktop/ScreenTool/image/
         while [  $COUNTER == 0 ]; do
         tesseract c.png output
     if grep -q Click "/root/Desktop/ScreenTool/image/output.txt"; then
        mosquitto_pub -h 192.168.1.103 -t test -m "Rain is here"
        echo -en "\007"
     fi
             cat "/root/Desktop/ScreenTool/image/output.txt"
    sleep 3;
  done

要在不等待命令完成的情況下執行命令，請使用&將其放在后台。

#!/bin/bash 
COUNTER=0
xterm -e mosquitto_sub -h 192.168.1.103 -t test &
mosquitto_pub -h 192.168.1.103 -t test -m "Connected"
cd Desktop/ScreenTool/image/
while [  $COUNTER == 0 ]; do
    tesseract c.png output
    if grep -q Click "/root/Desktop/ScreenTool/image/output.txt"; then
        mosquitto_pub -h 192.168.1.103 -t test -m "Rain is here"
        echo -en "\007"
    fi
    cat "/root/Desktop/ScreenTool/image/output.txt"
    sleep 3;
done
