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

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