NAME
file - determine file type
SYNOPSIS
file file ...
DESCRIPTION
    _F_i_l_e performs a series of tests on each argument in an
    attempt to classify it.  If an argument appears to be ascii,
    _f_i_l_e examines the first 512 bytes and tries to guess its
    language.
BUGS
    It often makes mistakes.  In particular it often suggests
    that command files are C programs.
