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