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.
