There are 50 csv files. each csv file have the same column's name. some content in the column are the same, some don't.
eg：now, i want to make a change to two column's content.Code:test1.csv, example1.csv, hello.csv, world.csv.......test70.csv.
a, all csv files have a column named qty. whose rows content are all 0. now, i want to change it into 888
b, all csv files have a column named img. whose rows content are all
If i open each csv file then do a search and replace. i fell it too bored.Code:upload/img1.jpg upload/img2.jpg upload/img3.jpg upload/img01.jpg upload/img14.jpg upload/img01.jpg .......
Thank you in advance.
