48 utility reads the given
50 and breaks it up into files of 1000 lines each.
57 reads from the standard input.
59 The options are as follows:
61 .It Fl a Ar suffix_length
64 letters to form the suffix of the file name.
65 .It Fl b Ar byte_count[suffix]
69 An optional suffix (as documented in
70 .Xr dehumanize_number 3 )
73 Use a numeric suffix instead of a alphabetic suffix.
74 .It Fl l Ar line_count
79 The file is split whenever an input line matches
81 which is interpreted as an extended regular expression.
82 The matching line will be the first line of the next output file.
83 This option is incompatible with the
90 If additional arguments are specified, the first is used as the name
91 of the input file which is to be split.
92 If a second additional argument is specified, it is used as a prefix
93 for the names of the files into which the file is split.
94 In this case, each file into which the file is split is named by the
95 prefix followed by a lexically ordered suffix using
97 characters in the range
101 is not specified, two letters are used as the suffix.
105 argument is not specified, the file is split into lexically ordered
106 files named with prefix
108 and with suffixes as above.
122 The maximum line length for matching patterns is 65536.
