split

Split a file into pieces. More information: https://www.gnu.org/software/coreutils/split.

• Split a file, each split having 10 lines (except the last split):
  split -l {{10}} {{path/to/file}}
• Split a file into 5 files. File is split such that each split has same size (except the last split):
  split -n {{5}} {{path/to/file}}
• Split a file with 512 bytes in each split (except the last split; use 512k for kilobytes and 512m for megabytes):
  split -b {{512}} {{path/to/file}}
• Split a file with at most 512 bytes in each split without breaking lines:
  split -C {{512}} {{path/to/file}}
