Hi,

The split command splits a file and gives the resulting files aaa, aab, aac, ... suffix. Is there a way to make it using numerical suffix instead, e.g. 001, 002, ... ?

If that is not possible, then how can I use the standard commands, e.g. tar, cpio, cat, gzip, etc. to achieve my goal? I cannot install any external program or script.

TIA.

You need to use csplit for this.

Example : split foo.txt into files that contain 10 lines each (assuming foo.txt has 100 lines), naming the files file_00, file_01, etc.

csplit -ks -f file_ foo.txt 10 {10}

Thank you.

But does csplit work with binary files?

Fsplit

Splits binary files into several pieces. By default, the pieces are conveniently floppy-sized.
