Splitting a file based on line number

Shell Programming and Scripting

Hi I have a file with over a million lines (rows) and I want to split everything from 500,000 to a million into another file (to make the file smaller). Is there a simple command for this?

Thank you

Phil

Take a look at split. E.g:

split -l 500000 infile

Try:

split -dl500000 -a1 file file

This will create file0, file1, ..., each having 500000 lines or less.

Try the split command, ls the files to be created, and you will know the answer you just asked.
