130 The file is split whenever an input line matches
132 which is interpreted as an extended regular expression.
133 The matching line will be the first line of the next output file.

141 If additional arguments are specified, the first is used as the name
142 of the input file which is to be split.
143 If a second additional argument is specified, it is used as a prefix
144 for the names of the files into which the file is split.
145 In this case, each file into which the file is split is named by the
146 prefix followed by a lexically ordered suffix using
148 characters in the range
