The
csplitcommand is pretty much made for this job:That will split
input.csvinto 100-line files for the first 200,000 lines in the file. The output files will beginoutput-csv.and will be followed by 4 digits. The-kmeans ‘do not clean up on receipt of a signal’. Adjust numbers according to size of input file and your whims and desires.Note the quirky behaviour of the first file, documented at the POSIX manual page linked to.
