split --lines=100 file 

to split file ,and output file has name :

Is there any way to make output 's name :

1,2,3,4 ...

OR

001,002,003,004,...

Answer 1

This should work for the second format you requested (000, 001, 002 etc.):

split --lines=100 -d -a 3 file ''

The double single-quotes at the end allow us to override the default prefix (which is x), and replace it with nothing. Try man split to see what the other arguments do.
