Usage

split [OPTION]... [FILE [PREFIX]]

Flags

Usage: split [OPTION]... [FILE [PREFIX]]
Output pieces of FILE to PREFIXaa, PREFIXab, ...;
default size is 1000 lines, and default PREFIX is 'x'.

With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
  -a, --suffix-length=N   generate suffixes of length N (default 2)
      --additional-suffix=SUFFIX  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 records per output file
  -d                      use numeric suffixes starting at 0, not alphabetic
      --numeric-suffixes[=FROM]  same as -d, but allow setting the start value
  -x                      use hex suffixes starting at 0, not alphabetic
      --hex-suffixes[=FROM]  same as -x, but allow setting the start value
  -e, --elide-empty-files  do not generate empty output files with '-n'
      --filter=COMMAND    write to shell COMMAND; file name is $FILE
  -l, --lines=NUMBER      put NUMBER lines/records per output file
  -n, --number=CHUNKS     generate CHUNKS output files; see explanation below
  -t, --separator=SEP     use SEP instead of newline as the record separator;
                            '\0' (zero) specifies the NUL character
  -u, --unbuffered        immediately copy input to output with '-n r/...'
      --verbose           print a diagnostic just before each
                            output file is opened
      --help     display this help and exit
      --version  output version information and exit

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/records
  l/K/N   output Kth of N to stdout without splitting lines/records
  r/N     like 'l' but use round robin distribution
  r/K/N   likewise but only output Kth of N to stdout

Examples

Split files default 1000 lines per file

split <file>

Split files with customize line numbers (-l)

Split a file with 200 lines per file

split -l200 <file> --verbose
creating file 'xaa'
creating file 'xab'
creating file 'xac'
creating file 'xad'
creating file 'xae'
creating file 'xaf'

Verify the lines of each file using below command

wc -l xa*
 200 xaa
 200 xab
 200 xac
 200 xad
 200 xae
  91 xaf
