從文件a中查找，並提取文件b及其整個括號

我有兩個文件，我想做的是使用歸檔一個並搜尋號碼文件b並列印整個括號，包括搜尋到的行。我不確定，是否是這個名字。

文件一：

300
302
303

文件b：

    [300] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },
    [301] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },
    [302] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },
    [303] = {
        name = "John",
        age = "12",
        address = {
        "Person street address"
        },
        job = "Marketing",
        job a = "some job",
        job b = {
        "His job description"
        },
        car = 0,
        salary = 0
    },

預期輸出：

    [300] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },
    [302] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },
    [303] = {
        name = "John",
        age = "12",
        address = {
        "Person street address"
        },
        job = "Marketing",
        job a = "some job",
        job b = {
        "His job description"
        },
        car = 0,
        salary = 0
    },

嘗試使用 awk，但無法使其工作。

awk 'NR==FNR{a[$1]=1;next} $1 in a && /\[$1\]/,/^\t\},/ {print}' a b > c

感謝您的幫助..

假設您無法存取此特定格式的解析器，並且您的記錄確實如您所示的那樣簡單且規則，則可以在每個 UNIX 機器上的任何 shell 中使用任何 awk：

$ cat tst.awk
NR == FNR {
    vals["["$1"]"]
    next
}
rec == "" { key = $1 }
{ rec = rec $0 ORS }
/^[[:blank:]]*},$/ {
    if ( key in vals ) {
        printf "%s", rec
    }
    key = rec = ""
}

。

$ awk -f tst.awk file_a file_b
    [300] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },
    [302] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },

使用以下命令進行測試並且工作正常

命令

for i in `cat filea`; do sed -n '/'$i'/,/^[[:space:]]\{4\}\},$/p' fileb; done

輸出

 [300] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },
    [302] = {
        name = "John",
        age = "12",
        address = {""},
        job = "Marketing",
        job a = "some job",
        job b = {"some job"},
        car = 0,
        salary = 0
    },
    [303] = {
        name = "John",
        age = "12",
        address = {
        "Person street address"
        },
        job = "Marketing",
        job a = "some job",
        job b = {
        "His job description"
        },
        car = 0,
        salary = 0
    },

如果您使用sed以下行可以幫助您。

while read n; do sed -n -e "/^\[$n\]/,/^},$/p" b.txt; done < a.txt
