124 The file is split whenever an input line matches
126 which is interpreted as an extended regular expression.
127 The matching line will be the first line of the next output file.
128 This option is incompatible with the
135 If additional arguments are specified, the first is used as the name
136 of the input file which is to be split.
137 If a second additional argument is specified, it is used as a prefix
138 for the names of the files into which the file is split.
139 In this case, each file into which the file is split is named by the
140 prefix followed by a lexically ordered suffix using
142 characters in the range
