Split a file into pieces.
Read the given file (or standard input if no file is specified) and break it up into files of 1000 lines each.
Syntax split [-b byte_count[k|m]] [-l line_count] [file [name]] Option -b Create smaller files byte_count bytes in length. `k' = kilobyte pieces `m' = megabyte pieces. -l Create smaller files line_count lines in length.
If additional arguments are specified, the first is used as the name of the input file which is to be split.
If a second additional argument 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 in the range of `aa-zz'. If the name argument is not specified, the file is split into lexically ordered files named in the range of `xaa-zzz'.
For historical reasons, if you specify name, split can only create 676 separate files. The default naming convention allows 2028 separate files.
