This manual page
documents the GNU version of
split .
split
creates one or more output files (as many as necessary) containing
consecutive sections of the
infile ,
or the standard input if none is given or the name `-' is given.
By default,
split
puts 1000 lines of the input file, or whatever is left if it is less
than that, into each output file.
The output file names consist of a prefix followed by a group of
letters, chosen so that concatenating the output files in sorted order
by file name produces the original input file, in order. The default
output file name prefix is `x'. If the
outfile-prefix
argument is given, it is used as the output file name prefix instead.
