NAME

       split - Splits a file into pieces

SYNOPSIS

   Current syntax
       split [-l line_count] [-a suffix_length] [file | -] [prefix]

       split -b  n [k|m] [-a suffix_length] [file | -] [prefix]

   Obsolescent syntax
       split [-number] [-a suffix_length] [file | -] [prefix]

OPTIONS

       Uses  suffix_length  letters  to  form  the suffix portion of the file names of the split file.	If -a is not specified, the default suffix
       length is two letters.  If the sum of the prefix and the suffix arguments would create a file  name  exceeding  NAME_MAX  bytes,  an  error
       occurs.	 In this case, split exits with a diagnostic message and no files are created.	Split a file into pieces n bytes in size.  Split a
       file into pieces n kilobytes (1024 bytes) in size.  Split a file into pieces n megabytes (1048576 bytes) in size.  Specifies the number	of
       lines  in each output file.  The line_count argument is an unsigned decimal integer.  The default value is 1000.  If the input does not end
       with a newline character, the partial line is included in the last output file.	Specifies the number of lines in each  output  file.   The
       default is 1000 lines per output file.  If the input does not end with a newline character, the partial line is included in the last output
       file.  (Obsolescent)

OPERANDS

       The pathname of the file to be split.

	      If you do not specify an input file, or if you specify -, the standard input is used.

DESCRIPTION

       The split command reads file and writes it in number-line pieces (default 1000 lines) to a set of output files.

       The size of the output files can be modified by using the -b or -l options.  Each output file is created with a unique suffix consisting of
       exactly	suffix	lowercase  letters from the POSIX locale.  The letters of the suffix are used as if they were a base-26 digit system, with
       the first suffix to be created consisting of all a characters, the second with b replacing the last a etc., until a name of all zs is  cre-
       ated.   By  default,  the  names  of  the output files are x, followed by a two-character suffix from the character set as described above,
       starting with aa, ab, ac, etc., and continuing until the suffix zz, for a maximum of 676 files.

       The value of prefix cannot be longer than the value of NAME_MAX from <limits.h> minus two.

       If the number of files required is greater than the maximum allowed by the effective suffix length (such that the last allowable file would
       be  larger  than  the  requested  size), split fails after creating the last possible file with a valid suffix.	The split command will not
       delete the files it created with valid suffixes.  If the file limit is not exceeded, the last file created contains the	remainder  of  the
       input file and thus might be smaller than the requested size.

EXIT STATUS

       The following exit values are returned: Successful completion.  An error occurred.

EXAMPLES

       To split a file into 1000-line segments, enter: split book

	      This  splits  book into 1000-line segments named xaa, xab, xac, and so forth.  To split a file into 50-line segments and specify the
	      file name prefix, enter: split -l50 book sect

	      This splits book into 50-line segments named sectaa, sectab, sectac, and so forth.

ENVIRONMENT VARIABLES

       The following environment variables affect the execution of split: Provides a default value for the internationalization variables that are
       unset or null. If LANG is unset or null, the corresponding value from the default locale is used.  If any of the internationalization vari-
       ables contain an invalid setting, the utility behaves as if none of the variables had been defined.  If set to a  non-empty  string  value,
       overrides  the  values of all the other internationalization variables.	Determines the locale for the interpretation of sequences of bytes
       of text data as characters (for example, single-byte as opposed to multibyte characters in arguments  and  input  files).   Determines  the
       locale for the format and contents of diagnostic messages written to standard error.  Determines the location of message catalogues for the
       processing of LC_MESSAGES.
