Question

我有一个包含一行的文本文件。

        <input type="button" value = "-" onclick="minusbot()" />    

        <input type="number" name="kgcount" id = "kilohere" value = "1" >

        <input type="button" value = "+" onclick="plusbot()" />                 

        <script>
            function minusbot()
            {
                document.getElementById('kilohere').value = parseInt(document.getElementById('kilohere').value) - 1;

                var checknumifzero = parseInt(document.getElementById('kilohere').value);

                if(checknumifzero < 1) //preventing to get negative value
                {
                    document.getElementById('kilohere').value = 1;
                }
            }   

            function plusbot()
            {
                document.getElementById('kilohere').value = parseInt(document.getElementById('kilohere').value) + 1;

                var checknumiffifty = parseInt(document.getElementById('kilohere').value);

                if(checknumiffifty > 50) //just a limit
                {
                    document.getElementById('kilohere').value = 50;
                }

            }


        </script>

我尝试过awk，但它仅显示最后一部分：

2019-06-19 09:00 Login successfully [ Section 1] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 2] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 3] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 4] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 5] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 6] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN Program Terminated...

awk '{for(i=1;i<=NF;i++) {if ($i == "Section") beginning=i; if($i== "OPEN") ending=i }; for (j=beginning;j<=ending;j++) printf $j" ";printf "\n"   }'

如何重新格式化为这种模式？

Section 6] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN

Answer 1

此命令在更一般的情况下有效（例如，如果没有Param1，Param2但有实际标识符），并且可以更精确地匹配您的预期输出：

sed 's/ \(Login successfully\|Program Terminated...\)//g; s/\[ /[/g; s/\(\[\|[Ss]tate\)/\n\1/g; s/\([A-Z][A-Za-z0-9]* :\)/\n\1/g'

工作方式：

该命令有4个单独的表达式，以;分隔：

s/ \(Login successfully\|Program Terminated...\)//g-删除不需要的Login successfully和Program Terminated...，并在其前面留一个空格
s/\[ /[/g-删除[后的空格
s/\(\[\|[Ss]tate\)/\n\1/g-在State或state
s/\([A-Z][A-Za-z0-9]* :\)/\n\1/g-在“ Params”之前添加换行符，其名称由大写字母（[A-Z]）和任何ASCII字母或数字（[A-Za-z0-9]）组成

示例：

$ STRING="2019-06-19 09:00 Login successfully [ Section 1] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 2] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 3] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 4] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 5] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 6] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN Program Terminated..."
$ echo $STRING | sed 's/ \(Login successfully\|Program Terminated...\)//g; s/\[ /[/g; s/\(\[\|[Ss]tate\)/\n\1/g; s/\([A-Z][A-Za-z0-9]* :\)/\n\1/g'

Answer 2

将[<space>替换为[，并在字符串[，Param和State之前添加换行符：

$ sed 's/\[ /[/g; s/\(\[\|Param\|State\)/\n\1/g' <<<'2019-06-19 09:00 Login successfully [ Section 1] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 2] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 3] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 4] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 5] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 6] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN Program Terminated...'
