NAME

     head - display first lines of a file


SYNOPSIS

     head [-n count] [file ...]


DESCRIPTION

     This filter displays the first count lines of each of the specified
     files, or of the standard input if no files are specified.  If count is
     omitted it defaults to 10.

     If more than a single file is specified, each file is preceded by a head-
     er consisting of the string ``==> XXX <=='' where ``XXX'' is the name of
     the file.

     The head utility exits 0 on success, and >0 if an error occurs.


COMPATIBILITY

     The historic command line syntax of head is supported by this implementa-
     tion.
