NAME

       split - split a file into pieces

SYNOPSIS

       split [-linecount | -l linecount] [-a suffixlength]
	    [file [name]]

       split [-b n | nk | nm] [-a suffixlength] [file [name]]

DESCRIPTION

       The  split  utility reads file and writes it in linecount-line pieces into a set of output-files. The name of the first output-file is name
       with aa appended, and so on lexicographically, up to zz (a maximum of 676 files). The maximum length of name is 2 characters less than  the
       maximum	filename length allowed by the filesystem. See statvfs(2). If no output name is given, x is used as the default (output-files will
       be called xaa, xab, and so forth).

OPTIONS

       The following options are supported:

       -linecount | -l linecount

	   Number of lines in each piece. Defaults to 1000 lines.

       -a suffixlength

	   Uses suffixlength letters to form the suffix portion of the filenames of the split file. If -a is not  specified,  the  default  suffix
	   length  is  2. If the sum of the name operand and the suffixlength option-argument would create a filename exceeding NAME_MAX bytes, an
	   error will result; split will exit with a diagnostic message and no files will be created.

       -b n

	   Splits a file into pieces n bytes in size.

       -b nk

	   Splits a file into pieces n*1024 bytes in size.

       -b nm

	   Splits a file into pieces n*1048576 bytes in size.

OPERANDS

       The following operands are supported:

       file    The path name of the ordinary file to be split. If no input file is given or file is -, the standard input will be used.

       name    The prefix to be used for each of the files resulting from the split operation. If no name argument is given, x will be used as the
	       prefix  of  the	output	files.	The  combined  length of the basename of prefix and suffixlength cannot exceed NAME_MAX bytes. See
	       OPTIONS.

USAGE

       See largefile(5) for the description of the behavior of split when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect the execution of split: LANG, LC_ALL, LC_CTYPE,  LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0     Successful completion.

       >0    An error occurred.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
