Question

我有一个场景，我会得到以下格式的输出：

public class WinExitSignal : IExitSignal
{
    public event EventHandler Exit;

    [DllImport("Kernel32")]
    public static extern bool SetConsoleCtrlHandler(HandlerRoutine Handler, bool Add);

    // A delegate type to be used as the handler routine
    // for SetConsoleCtrlHandler.
    public delegate bool HandlerRoutine(CtrlTypes CtrlType);

    // An enumerated type for the control messages
    // sent to the handler routine.
    public enum CtrlTypes
    {
        CTRL_C_EVENT = 0,
        CTRL_BREAK_EVENT,
        CTRL_CLOSE_EVENT,
        CTRL_LOGOFF_EVENT = 5,
        CTRL_SHUTDOWN_EVENT
    }

    /// <summary>
    /// Need this as a member variable to avoid it being garbage collected.
    /// </summary>
    private HandlerRoutine m_hr;

    public WinExitSignal()
    {
        m_hr = new HandlerRoutine(ConsoleCtrlCheck);

        SetConsoleCtrlHandler(m_hr, true);

    }

    /// <summary>
    /// Handle the ctrl types
    /// </summary>
    /// <param name="ctrlType"></param>
    /// <returns></returns>
    private bool ConsoleCtrlCheck(CtrlTypes ctrlType)
    {
        switch (ctrlType)
        {
            case CtrlTypes.CTRL_C_EVENT:
            case CtrlTypes.CTRL_BREAK_EVENT:
            case CtrlTypes.CTRL_CLOSE_EVENT:
            case CtrlTypes.CTRL_LOGOFF_EVENT:
            case CtrlTypes.CTRL_SHUTDOWN_EVENT:
                if (Exit != null)
                {
                    Exit(this, EventArgs.Empty);
                }
                break;
            default:
                break;
        }

        return true;
    }


}

我能够将整个结果存储到bash变量中。

例如，我创建了一个bash变量1,2,3,4,5,6||7,8,9,10,11,12||13,14,15,16,17,18||19,20,21,22,23,24和其他6个名为myvar的变量。 a,b,c,d,e,f包含上述结果集。

我需要的是当我在第一个循环中循环myvar时，它应分配如下：

myvar

准备一个html正文并发送给它并在第二个循环中

a=1,b=2,c=3,d=4,e=5,f=6

再次准备一个html正文并通过

发送

我对循环部分感到震惊

然后做一些html电子邮件正文，我只能返回

时才能这样做

1,2,3,4,5,6-

您可以通过设置IFS='|'来拆分输入行，但遗憾的是您使用||作为分隔符。 This answer显示了使用和IFS=''执行第二个数组参数扩展的技巧。在您的情况下，这相当于：

#!/bin/bash

# '(' execute the following commands in a subshell, see `man bash` (search for
# "Compound Commands").
(

# disable filename expansion
set -f

input="1,2,3,4,5,6||7,8,9,10,11,12||13,14,15,16,17,18||19,20,21,22,23,24"

# split by '|'
IFS='|'
lines=(${input})

# remove empty elements
IFS=""
lines=(${lines[@]})

for ((i=0; i < ${#lines[@]}; i++)); do
  echo "Processing ${i}: '${lines[${i}]}'"

  IFS=','
  elements=(${lines[${i}]})

  for ((j=0; j < ${#elements[@]}; j++)); do
    echo "  found element ${elements[${j}]}"
  done

  # here you can either use ${elements[${0}]}, ..., ${elements[${5}]} directly
  # or you can assign them to your variables:
  # set a="${elements[${0}]
  # set b="${elements[${1}]
  # ...

done

)

这只是您可以扩展的示例

下面你可以使用$ 1，$ 2，$ 3，$ 4等进行进一步处理（比如分配变量a，b c ..）或直接使用$ variables等。

x="1,2,3,4,5,6||7,8,9,10,11,12||13,14,15,16,17,18||19,20,21,22,23,24"
echo $x | cut -d'|' -f1- --output-delimiter=$'\n' | sed -e '/^[ ]*$/d' > /tmp/data.txt
for line in `cat /tmp/data.txt`; do awk -F',' '{print $1, $2, $3, $4, $5}' <<< $line; done

请注意cat /tmp/data.txt

附近（需要）“后引号字符”

如何拆分由＆＃39;，＆＃39;分隔的字段列表和＆＃39; ||＆＃39;？
