hello and thx for answering me so fast

sorry i was wrong, actually it's a text file of 200 MegaBytes !
i need to change the format of the content so it will be possible to insert the datas in a database.

i googled for "split" but i found it works with bytes and i am not sure that 1 character = 1 byte

i've heard about awk and i keep looking, if there's something that works i'll tell you
