无法使用 exit 命令停止脚本 l 循环

我的脚本中有一个调试功能（通过 nemo.action 运行），它使用 zenith 弹出窗口询问用户在发生错误时是否要停止或继续。但是，当这种情况发生在循环内时，exit脚本中的命令 或 会被完全忽略。

无论如何，没有强制退出来完全停止脚本吗？ 我希望它像渡渡鸟一样死掉！ 应该是可以自己杀掉的..

这是我调试的一部分：

44:57.198 • Stopped while renaming file/directory  - it failed
44:57.199 • Error triggered, issue:
44:57.201 • Stopped while renaming file/directory.\nSee debug log for more info...

45:20.563 • Stopping the script by user request due error. ()
   ^^^ this line gets written to the log when the user choose to exit
 vvv but it continues to run the script until a new error occurs
45:20.564 • Could not find ‘/temp/sani.txt‘ Have no value to assign to $jdir0
45:20.566 • Error triggered, issue:
45:20.567 • Could not find ‘/temp/sani.txt‘ Have no value to assign to $jdir0
45:24.670 • Stopping the script by user request due error. ()
^^^ and when pressing stop here, the script will halt..

这是被触发的相同错误函数：

jerror () {
    enl
    jdbugen "Error triggered, issue:\n\n"
    jdbug "$@"
    debuglogread=$(tail -10 "$debuglog")
    zenity --question  --text="($jdec)Error Triggered\nIssue:\n\n ‘$@‘\n\n$debuglogread\n\nContinue?"  --width=400 --height=200
    jdec=$?
    if [ "$jdec" != 0 ]
    then
        jdbug "Stopping the script by user request due error. ($jdeck)"
        exit 1
    else
        jdbug "User choose to continue the script"
    fi
    enl
}

脚本的这部分正在调用函数：

mv -f  -v "$item" "$path/$name"    &>>  $debuglog  # Rename
    jok=$?
    if [ $jok -ne 0 ]
    then
        jdbug "Stopped while renaming file/directory  - it failed"
        jerror "Stopped while renaming file/directory.\nSee debug log for more info..."
    fi

我发现这并不容易，所以我通过将退出请求存储在文件中来解决它。

通过添加字符串，printf "%d" "1" > "/tmp/exitcode.dat"我将值 1 存储在临时文件中。

   printf "%d" "1" > "/tmp/exitcode.dat"  # Storing the exit code
   exit 1                                # Will break of of the loop

循环之后“完毕“命令，您将需要重新读取文件

if [[ -f "/tmp/exitcode.dat" ]] 
then
 jexit="$(</tmp/exitcode.dat)"   # Read the stored code
 rm "/tmp/exitcode.dat"              # Clean up and remove the file
 if [ $jexit eq 1 ]; then exit 1;     # Check if exit code is 1
fi

更短的代码就是创建文件。

    touch "/tmp/exitcode.dat"      # Create the file
    exit 1                         # Exit the loop

并在之后完毕命令

if [[ -f "/tmp/exitcode.dat" ]]; Then   # See if the file exists
        rm "/tmp/exitcode.dat"              # Cleanup
        exit 1                    # Exit the script
fi
