Question

我有两个文件。每个文件都有唯一的job_id值。

shop_file.txt此文件的job_id值始终等于21。

407486;{"shop_id":"407486","job_id":21}
163181148;{"shop_id":"163181148","job_id":21}
1510942977;{"shop_id":"1510942977","job_id":21}

dish_file.txt此文件的job_id值始终等于23。

7491777303;{"shop_id":"407486","dish_id":"7491777303","job_id":23}
1667364700;{"shop_id":"1664150969","dish_id":"1667364700","job_id":23}
1932540486;{"shop_id":"1932534033","dish_id":"1932540486","job_id":23}
1932540468;{"shop_id":"1932534033","dish_id":"1932540468","job_id":23}
1932540477;{"shop_id":"1932534033","dish_id":"1932540477","job_id":23}
1932540456;{"shop_id":"1932534033","dish_id":"1932540456","job_id":23}
1673778516;{"shop_id":"1478428493","dish_id":"1673778516","job_id":23}
1673462967;{"shop_id":"1642179256","dish_id":"1673462967","job_id":23}
1721592562;{"shop_id":"1697153440","dish_id":"1721592562","job_id":23}
8491777303;{"shop_id":"407486","dish_id":"8491777303","job_id":23}

相同的shop_id值必须存在两个文件，如何使用awk获取此结果。

7491777303;{"shop_id":"407486","dish_id":"7491777303","job_id":23}
8491777303;{"shop_id":"407486","dish_id":"8491777303","job_id":23}

Answer 1

理想情况下，应该这样解析JSON数据，但要假定结构是固定的，并且如图所示是一致的（重要的是，shop_id是第一个键，其值中不得包含任何逗号）：

$ awk -F'[;,]' 'NR==FNR {a[$2]; next} $2 in a' shop_file.txt dish_file.txt
7491777303;{"shop_id":"407486","dish_id":"7491777303","job_id":23}
8491777303;{"shop_id":"407486","dish_id":"8491777303","job_id":23}

Answer 2

下面的grep和sed衬里应该对给定的示例有所帮助：

grep -f <(sed 's/.*\("shop_id"[^,]*\).*/\1/ shopFile) dishFile
