	13 .SH DESCRIPTION
	14 .I Split
	15 reads
	16 .I file
	17 (standard input by default)
	18 and writes it in pieces of 1000
	19 lines per output file.
	20 The names of the
	21 output files are
	22 .BR xaa ,
	23 .BR xab ,
	24 and so on to
	25 .BR xzz .
	26 The options are
	27 .TP
	28 .BI -n " n"
	29 Split into
	30 .IR n -line
	31 pieces.
	32 .TP
	33 .BI -l " n"
	34 Synonym for
	35 .B -n
	36 .IR n ,
	37 a nod to Unix's syntax.
	38 .TP
	39 .BI -e " expression"
	40 File divisions occur at each line
	41 that matches a regular
	42 .IR expression ;
	43 see
	44 .IR regexp (7).
	45 Multiple
	46 .B -e
	47 options may appear.
	48 If a subexpression of
	49 .I expression
	50 is contained in parentheses
	51 .BR ( ... ) ,
	52 the output file name is the portion of the
	53 line which matches the subexpression.
	54 .TP
	55 .BI -f " stem
	56 Use
	57 .I stem
	58 instead of
	59 .B x
	60 in output file names.

	62 .BI -s " suffix
	63 Append
	64 .I suffix
	65 to names identified under
	66 .BR -e .
	67 .TP
	68 .B -x
	69 Exclude the matched input line from the output file.
	70 .TP
	71 .B -i
	72 Ignore case in option
	73 .BR -e ;
	74 force output file names (excluding the suffix)
	75 to lower case.
