从文件a中查找，并提取文件b及其整个括号

我有两个文件，我想要做的是使用归档一个并搜索号码文件b并打印整个括号，包括搜索到的行。我不确定，是否是这个名字。

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
    },

预期输出：

    [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
    },

尝试使用 awk，但无法使其工作。

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

感谢您的帮助..

假设您无权访问这种特定格式的解析器，并且您的记录确实像您所显示的那样简单和规则，则可以在每个 UNIX 机器上的任何 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
    },

使用以下命令进行测试并且工作正常

命令

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

输出

 [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以下行可以帮助您。

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