unix – split large text file into smaller one

run:

split -a 5 -d -l 10000 my_file.txt my_file_

usage:

split -a 5 -d -l <nb_lines_per_file> <file_to_split> <split_prefix>
  • d = numeric numbering (instead of alphabetical)
  • l = number of lines per split files
  • a = number of characters used for numbering (increase it in case of exhaustion)
