SPLIT(1) UNIX Programmer's Manual SPLIT(1)

NAME

    split - split a file into pieces

SYNOPSIS

    split [ -_n ] [ file [ name ] ]

DESCRIPTION

    _S_p_l_i_t reads _f_i_l_e and writes it in _n-line pieces (default
    1000), as many as necessary, onto a set of output files.
    The name of the first output file is _n_a_m_e with aa appended,
    and so on lexicographically.  If no output name is given, x
    is default.

    If no input file is given, or if - is given in its stead,
    then the standard input file is used.
