split - split a file into pieces


split [ OPTION]... [INPUT [PREFIX]]

Mandatory arguments to long options are mandatory for short options too.
-a, --suffix-length=N
generate suffixes of length N (default 2)
append an additional SUFFIX to file names
-b, --bytes=SIZE
put SIZE bytes per output file
-C, --line-bytes=SIZE
put at most SIZE bytes of lines per output file
-d, --numeric-suffixes[=FROM]

-e, --elide-empty-files

-l, --lines=NUMBER
put NUMBER lines per output file
-n, --number=CHUNKS

-u, --unbuffered

The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).
CHUNKS may be: N split into N files based on size of input K/N output Kth of N to stdout l/N split into N files without splitting lines l/K/N output Kth of N to stdout without splitting lines r/N like 'l' but use round robin distribution r/K/N likewise but only output Kth of N to stdout
