在表格中的时间列中添加缺失的冒号

我有这样的表：

"Date","Time","Open","High","Low","Close","Volume"
06/28/2004,0931,37.49,37.50,37.45,37.46,1049200
06/28/2004,0932,37.48,37.50,37.45,37.48,450700
06/28/2004,0933,37.48,37.50,37.46,37.49,493700
06/28/2004,0934,37.49,37.50,37.47,37.47,756100
06/28/2004,0935,37.48,37.49,37.46,37.48,309000

不幸的是，时间列只是数字，并且:在数字对之间缺失。我怎样才能纠正这个问题，以便表中的时间正确显示，如下所示：

"Date","Time","Open","High","Low","Close","Volume"
06/28/2004,09:31,37.49,37.50,37.45,37.46,1049200
06/28/2004,09:32,37.48,37.50,37.45,37.48,450700
06/28/2004,09:33,37.48,37.50,37.46,37.49,493700
06/28/2004,09:34,37.49,37.50,37.47,37.47,756100
06/28/2004,09:35,37.48,37.49,37.46,37.48,309000

答案1

awk -vFS="" -vOFS="" 'NR>1 {$13=$13":"}1' file

"Date","Time","Open","High","Low","Close","Volume"
06/28/2004,09:31,37.49,37.50,37.45,37.46,1049200
06/28/2004,09:32,37.48,37.50,37.45,37.48,450700
06/28/2004,09:33,37.48,37.50,37.46,37.49,493700
06/28/2004,09:34,37.49,37.50,37.47,37.47,756100
06/28/2004,09:35,37.48,37.49,37.46,37.48,309000

-vFS="" -vOFS=""将输入和输出字段分隔符设置为非。

NR>1以避免第一行发生更改，这意味着更改将从第 2 行开始应用

{$13=$13":"}将在字符串 13 之后插入冒号
