bash移动选择字段以匹配两个目录中的文件前缀

Question

在下面bash我尝试使用123_Last-First的前缀file1来匹配123_Last-First中的前缀file2。始终会找到匹配项（即如果有file1则必须有file2）。在file2中$5，&6和$7（始终以制表符分隔）的内容

$5 = Total_Targets with value under it that can be a decimal or integer

$6 = Targets_less_than250x with value under it that can be a decimal or integer

$7 = Percent_more_than250x with value under it that can be a decimal or integer

会在标题Quality metrics下复制到它。下面执行但没有产生输出。我添加了评论来帮助和展示我的想法。谢谢你:)。
