72 reads from the standard input.
74 The options are as follows:
75 .Bl -tag -width indent
79 letters to form the suffix of the file name.
86 is appended to the number, the file is split into
91 is appended to the number, the file is split into
99 The file is split whenever an input line matches
101 which is interpreted as an extended regular expression.
102 The matching line will be the first line of the next output file.
103 This option is incompatible with the
110 If additional arguments are specified, the first is used as the name
111 of the input file which is to be split.
112 If a second additional argument is specified, it is used as a prefix
113 for the names of the files into which the file is split.
114 In this case, each file into which the file is split is named by the
115 prefix followed by a lexically ordered suffix using
117 characters in the range
118 .Dq Li a Ns - Ns Li z .
121 is not specified, two letters are used as the suffix.
125 argument is not specified, the file is split into lexically ordered
126 files named with prefixes in the range of
128 and with suffixes as above.
