- Program dsplit: Splits a large file into pieces.
-
- Usage:
- dsplit [-size nnn] [input_file [output_base]]
- Size is size of each output file, in bytes. The default is 1457000,
- enough to fill a "1.44MB" diskette, save 152 bytes.
- input_file is the name of the file to split up. A dash (-) indicates
- standard input. Defaults to standard input.
- output_base is the name of the output files to be written, minus the
- extension. Dsplit adds suffixes 000, 001, ...
- The default base name is dsplit.
