ENVIRONMENT VARIABLES
       The  following environment variables affect the execution of head: Pro‐
       vides 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,	 over‐
       rides  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 multi‐
       byte 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  process‐
       ing of LC_MESSAGES.
