Question

我在下面有这个脚本

#!/bin/bash
function labels2 () {
    awk '
    /[0-9]/{
    print substr($3,length($3)-11), $3
    }' $@ | /bin/sort -u  | awk '{print "BUILD: " NR, $2}'
}

function labels () {
    awk '
    /[0-9]/{
    BL[$3] = substr($3,length($3)-11)
    }
    END {
    asort(BL)
    for (i in BL) {
        print i, BL[i]
    }
    }' $@
}


labels $@

for a in $@
do
    labels $@ | gawk '
    /BUILD:/ {
    BUILD[$2] = $3
    BUILDCNT ++
    next
    }
    /[0-9]/ {
    DATEd[$3] = $1
    TIMEd[$3] = $2
    MODULESd[$3] = $4
    CASESd[$3] = $5
    FAILEDd[$3] = $6
    COVERd[$3] = $7
    LOCd[$3] = $8
    }
    END {
    SUBSYSTEM=substr(FILENAME, 1, length(FILENAME)-7)
    LABEL= "\"" toupper(SUBSYSTEM) "\""

当使用当前文本文件gps.txt

“feeded”时，它会给出以下输出

2011-01-22 22:12 P16A22_110114072915 22 1312 75 13.55 1399
_

#{
"buildnames": {
        "label": "buildnames",
        "data": [
        ]
        }
};
#{
"subsystem": "GPS",
    "date": {
        "label": "GPS",
        "data": [
            [0, "1"],
        ]
    },
        "time" : {
        "label": "GPS",
        "data": [
            [0, "110114072915"],
        ]
    },
        "modules" : {
        "label": "GPS",
        "data": [
        ]
    },
        "cases" : {
        "label": "GPS",
        "data": [

    },
        "failed" : {

        "cover" : {
        "label": "GPS",
        "data": [

        "loc" : {
        "label": "GPS",
        "data": [
        ]
    }
    };

我想看的是这个

#{
"buildnames": {
        "label": "buildnames",
        "data": [[0,"BUILD: 1 P16A22_110114072915"]
        ]
        }
};
#{
"subsystem": "GPS",
    "date": {
        "label": "GPS",
        "data": [
            [0, "2011-01-22"],
        ]
    },
        "time" : {
        "label": "GPS",
        "data": [
            [0, "22:12"],
        ]
    },
        "modules" : {
        "label": "GPS",
        "data": [[0,22]
        ]
    },
        "cases" : {
        "label": "GPS",
        "data": [[0,1312]
        ]
    },
        "failed" : {
        "label": "GPS",
        "data": [[0,75]
        ]
    },
        "cover" : {
        "label": "GPS",
        "data": [[0,13.55]
        ]
    },
        "loc" : {
        "label": "GPS",
        "data": [[0,1399]
        ]
    }
    };

所以将这些问题分解为子问题

为什么行1 110114072915位于顶部，如何将其删除？

如何使用labels2()函数，以便它(BUILD: 1 P16A22_110114072915)的输出符合buildnames这样的

"buildnames": {
    "label": "buildnames",
    "data": [[0,"**BUILD: 1 P16A22_110114072915**"]
    ]
    }

这是最后一个问题：为什么这不起作用MODULESd[$3] = $4，CASESd[$3] = $5等......当我循环播放并打印出来时，它就变成了什么。

请注意这里将继续扩展文本文件gps.txt，以便将来可能会有50行，如果sollution仍然可以正常工作=）

我知道这变成了很多文字，我为此道歉，我可能无法得到所有问题的答案，但如果你有一个想法如何取得任何一些我会更乐意，因为我我目前陷入困境，不知道该怎么做我想做的事情。不幸的是，这种做法是我唯一的选择。

感谢您的努力=）

Answer 1

这都是基于心理处理 - 我还没有实际运行命令。查看该文本文件的示例

会有所帮助

1）为什么第1行110114072915位于顶部，如何将其删除？

在循环打印信息之前看起来像是labels $@调用。摆脱它。

2）您可能应该将该逻辑迁移到底部awk命令中。关联数组赋值可以在第二个块/[0-9]/中完成，END逻辑可以直接放在大脚本的END块中。

3）文本文件每行有8个字段吗？作为调试，使用print NF > "/dev/stderr";之类的东西来确保在设置变量时确实存在8个字段。

Answer 2

1）为什么第1行110114072915位于顶部，如何将其删除？

Foo Bah正确回答了这个问题。

这对我来说不对：

for a in $@
do
labels $@ | gawk '

为什么要循环遍历所有参数，然后运行labels $@而不是labels $a？

2）我如何使用函数labels2（）

我会运行该函数并将输出分配给awk变量：

labels $@ | gawk -v "bnames=\"$(labels $a)\"" '

然后在awk脚本中使用该变量：

    print "        \"data\": [", bnames

3）这是最后一个问题：为什么不这样做

我不知道，但除非你把问题分解成小块并自己调试，否则你永远不会弄明白。如果你写了一百行awk脚本并且它不起作用，那么答案就是尝试让一个更简单的十行版本工作，然后逐个增长并检查每个部分的工作原理。

需要一些好的bash程序员的帮助
