SPLIT(1)                                                 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 regu-
               lar expression; see regexp(6). Multiple -e options may
               appear.  If a subexpression of expression is contained
               in parentheses (...), the output file name is the por-
               tion 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.
