— split a
file into pieces
utility reads the given
, or standard input if no file is
specified, and breaks it up into files of 1000 lines each.
itself is not altered.
The options are as follows:
- Use suffix_length letters
to form the suffix of the file name (see below). The default suffix length
- Create files byte_count
bytes in length. If ‘k’ is appended to the number, the file
is split into byte_count kilobyte pieces.
If ‘m’ is appended to the number, the file is split into
byte_count megabyte pieces.
- Create files line_count
lines in length.
- The file is split whenever an input line matches
pattern, which is interpreted as an
extended regular expression. The matching line will be the first line of
the next output file. This option is incompatible with the
-b and -l
is specified, it is used as a prefix
for the names of the files into which the file is split. In this case, each
file into which the file is split is named by the prefix followed by a
lexically ordered suffix using suffix_length
characters in the range “a-z”.
If the name
argument is not specified, the file
is split into lexically ordered files named with the prefixes
‘x’, ‘y’, and ‘z’.
utility exits 0 on success,
