116 The file is split whenever an input line matches
118 which is interpreted as an extended regular expression.
119 The matching line will be the first line of the next output file.
120 This option is incompatible with the
127 If additional arguments are specified, the first is used as the name
128 of the input file which is to be split.
129 If a second additional argument is specified, it is used as a prefix
130 for the names of the files into which the file is split.
131 In this case, each file into which the file is split is named by the
132 prefix followed by a lexically ordered suffix using
134 characters in the range
135 .Dq Li a Ns - Ns Li z .
