split命令

NAME
     split - split a file into pieces

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 lexicograph-
     ically,  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 linecountumber  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 diag-
                             nostic  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 result-
              ing  from  the split operation. If no name argument
              is given, x will be used as the prefix of the  out-
              put  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_MESSAGES, and NLSPATH.


EXIT STATUS
     The following exit values are returned:


     0        Successful completion.


     >0       An error occurred.
