52 utility reads the given
54 and breaks it up into files of 1000 lines each.
61 reads from the standard input.
63 The options are as follows:
65 .It Fl a Ar suffix_length
68 letters to form the suffix of the file name.
69 .It Fl b Ar byte_count[k|m]
75 is appended to the number, the file is split into
80 is appended to the number, the file is split into
83 .It Fl l Ar line_count
88 The file is split whenever an input line matches
90 which is interpreted as an extended regular expression.
91 The matching line will be the first line of the next output file.
92 This option is incompatible with the
99 If additional arguments are specified, the first is used as the name
100 of the input file which is to be split.
101 If a second additional argument is specified, it is used as a prefix
102 for the names of the files into which the file is split.
103 In this case, each file into which the file is split is named by the
104 prefix followed by a lexically ordered suffix using
106 characters in the range
110 is not specified, two letters are used as the suffix.
114 argument is not specified, the file is split into lexically ordered
115 files named with prefix
117 and with suffixes as above.
131 The maximum line length for matching patterns is 65536.
