我有一些包含数万行格式的文件:

value1, value2, value3, value4, value5, value6, value7, value8, value9, value10
value1, value2, value3, value4, value5, value6, value7, value8, value9, value10
value1, value2, value3, value4, value5, value6, value7, value8, value9, value10

我想替换value10一定数量(比方说x).所以结果应该是:

value1, value2, value3, value4, value5, value6, value7, value8, value9, x
value1, value2, value3, value4, value5, value6, value7, value8, value9, x
value1, value2, value3, value4, value5, value6, value7, value8, value9, x

我想用正则表达式来做这件事.我有Sublime Text作为文本编辑器.
