SPLIT(1)                    General Commands Manual                   SPLIT(1)

NAME
       split - split a file into pieces

SYNOPSIS
       split [ option ...  ] [ file ]

DESCRIPTION
       Split reads file (standard input by default) and writes it in pieces of
       1000  lines  per  output  file.  The names of the output files are xaa,
       xab, and so on to xzz.  The options are

       -n n   Split into n-line pieces.

       -l n   Synonym for -n n, a nod to Unix's syntax.

       -e expression
              File divisions occur at each line that matches a regular expres‐
              sion; see regexp(6).  Multiple -e  options  may  appear.   If  a
              subexpression  of  expression is contained in parentheses (...),
              the output file name is the portion of the  line  which  matches
              the subexpression.

       -f stem
              Use stem instead of x in output file names.

       -s suffix
              Append suffix to names identified under -e.

       -x     Exclude the matched input line from the output file.

       -i     Ignore case in option -e; force output file names (excluding the
              suffix) to lower case.
