hi guys newbie here. need help

i have a text file which contains:


0978678787,reminder of your pending trans:,VL 1,OT 1,PL 4
0944673451,reminder of your pending trans:,VL 5,OT 3,PL 4
0934678787,reminder of your pending trans:,VL 6,OT 2,PL 5


so

basically this contains mobile numbers and message to send..

i want to create a script that separates each line to a new file


like file 1 contains:

0978678787,reminder of your pending trans:,VL 1,OT 1,PL 4

file 2 contains

0944673451,reminder of your pending trans:,VL 5,OT 3,PL 4
