Do you mean what are the command line arguments to split? Have a look at man split .

You never answered Scrutinizer's question: Is this homework?

What shell are you using?

PS How do the command line arguments in ./a.sh 2 1000 5 relate to your original request to put 100 lines in one file and split the remainder in 1000 line chunks?

I don't get it. Shouldn't the number of records in the last file be whatever is leftover after putting the first 100 lines from your input file in one file, and putting 1000 lines in subsequent files until less than 1000 lines are left? Are you saying that if your input file contains 1500 lines, you want 100 lines in one output file, 1000 lines in another file, 367 lines in the next file, and 33 lines in the last file? Why shouldn't it be 100 line in the first file, 1000 lines in the second file and 400 lines in the last file?

And, message #16 in this thread you said you wanted to call your script as:
Code:
./a.sh 2 1000 5

I see where the 1000 makes sense, but I don't understand what the 2 and the 5 are intended to tell your script. Why isn't the script to be invoked with something like:
Code:
./a.sh lines_to_go_in_file1 max_lines_to_go_in_remaining_files input_filename
