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


NAME

    look - find lines in a sorted list

SYNOPSIS

    look [ -df ] string [ file ]

DESCRIPTION

    _L_o_o_k consults a sorted _f_i_l_e and prints all lines that begin
    with _s_t_r_i_n_g.  It uses binary search.
    The options d and f affect comparisons as in _s_o_r_t(1):
    d   `Dictionary' order: only letters, digits, tabs and
        blanks participate in comparisons.
    f   Fold.  Upper case letters compare equal to lower case.
    If no _f_i_l_e is specified, /_u_s_r/_d_i_c_t/_w_o_r_d_s is assumed with
    collating sequence -df.
