sed 's|^([[0-9]])|##1|'
First try it inside vi. Worked for me. Then put it in the korn shell script.
Good luck.

sed 's|^([[0-9]])|##1|'
means...
1. s=In SED, use substitute
2. |^([[0-9]])|=find the beginning of line with number
3. |##1|=insert ## there.
Your input is
1212, dasfads, jkdfdas
kdfafadsf
2223, dfjaksd, dfjadsf,kjdfkad
5454, kdfjaksd, 343,mdsfas
adfasd
dasdf,asdfas, adfas.
Output is
##1212, dasfads, jkdfdas
kdfafadsf
##2223, dfjaksd, dfjadsf,kjdfkad
##5454, kdfjaksd, 343,mdsfas
adfasd
dasdf,asdfas, adfas.
