OPTIONS

       The  default  count  is 10.  [Tru64 UNIX]  Specifies the number of bytes to display. If the last byte written is not a newline character, a
       newline character is appended to the output.  Specifies the number of lines to display Works exactly as -n lines.  Obsolescent.

OPERANDS

       Path name of the input file. If you do not specify a file, head reads standard input.

ENVIRONMENT VARIABLES

       The  following environment variables affect the execution of head: Provides a default value for the internationalization variables that are
       unset or null. If LANG is unset or null, the corresponding value from the default locale is used.  If any of the internationalization vari-
       ables  contain  an  invalid setting, the utility behaves as if none of the variables had been defined.  If set to a non-empty string value,
       overrides the values of all the other internationalization variables.  Determines the locale for the interpretation of sequences  of  bytes
       of  text  data  as  characters  (for example, single-byte as opposed to multibyte characters in arguments and input files).  Determines the
       locale for the format and contents of diagnostic messages written to standard error.  Determines the location of message catalogues for the
       processing of LC_MESSAGES.
