Split a file into pieces. More information: https://www.gnu.org/software/coreutils/manual/html_node/split-invocation.html.

• 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
