Question

我正在制作一个像这样的终端上运行的脚本

#!/bin/bash
COUNTER=0
         while [  $COUNTER -lt 10 ]; do
             echo The counter is $COUNTER
             yoooooooo
             sleep 2
             let COUNTER=COUNTER+1 
         done

exit

但是一旦计数器达到9并且while循环停止，终端将不会以命令“exit”关闭。

这是输出

pi@raspberrypi:~/Desktop $ ./sxdd
The counter is 0
./sxdd: line 7: yoooooooo: command not found
The counter is 1
./sxdd: line 7: yoooooooo: command not found
The counter is 2
./sxdd: line 7: yoooooooo: command not found
The counter is 3
./sxdd: line 7: yoooooooo: command not found
The counter is 4
./sxdd: line 7: yoooooooo: command not found
The counter is 5
./sxdd: line 7: yoooooooo: command not found
The counter is 6
./sxdd: line 7: yoooooooo: command not found
The counter is 7
./sxdd: line 7: yoooooooo: command not found
The counter is 8
./sxdd: line 7: yoooooooo: command not found
The counter is 9
./sxdd: line 7: yoooooooo: command not found
pi@raspberrypi:~/Desktop $

它永远不会退出......我该如何解决这个问题？

Answer 1

终端不会以命令“exit”
关闭

那是因为你在脚本中运行exit命令。 kill $pidOfTheTerminalWindow表示“退出脚本”，而不是“退出终端”。如果要从脚本关闭终端窗口，则可能必须使用source sxdd等命令。

作为替代方案，您可以 source 脚本，即执行脚本，就像您直接在命令行中键入脚本一样。使用

. sxdd

或

Answer 2

尝试像这样运行脚本： exec ./sxdd

它用您的脚本替换shell进程，当脚本退出窗口时将关闭。

Bash：脚本中的退出不会关闭终端
