每个人每一页的标题

Question

我的file.txt：

Adam , 111
Adam ,222
Adam ,333
Tom ,111
Tom , 222
Tom, 333
Dick, 111
Dick, 222
Dick ,333

预期输出为：

My list
-----------------------
    List for Adam
-----------------------
    Adam 111
    Adam 222
    Adam 333
    End of list for Adam
.    My list
.   -------------------
    List for Tom
.   ------------------
    Tom 111
    Tom 222
    Tom 333
    End of list for Tom
.    My list
    ----------------------
    List. For Dick
.   ----------------------
    Dick 111
    Dick 222
    Dick 333
    End of list for Dick

我希望通过特定列中的人员姓名来溢出我的文件，并使用以下方法添加页眉页脚：

awk 'BEGIN {pttern } {action} END{pater}' myfile.txt

Awk方法：

awk 'BEGIN{ head = "List for"; tail = "End for list for" }
     !a[$1]++ {
         if (NR > 1) print tail, name ORS;
         print head, $1;
         name = $1
     }
     END{ print tail, name }1' file

输出：

List for Adam
Adam 111
Adam 222
Adam 333
End for list for Adam

List for Tom
Tom 111
Tom 222
Tom 333
End for list for Tom
