Alternatives
  • The free (as in beer) program GSplit splits the file. I was able to split a 16GB text file successfully minutes after downloading. The documentation is okey. (Runs on Windows.)
GSplit: Split large text and similar files like large server logs and other
CSV files by number of lines or occurrences of a specified pattern. Optionally
insert headers into each piece file.
  • loop over the lines of the huge file and write to smaller files
  • and memmapfile
