       The  following  environment variables affect the execution
       of unalias: 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 variables
 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).  Determines
       the locale used to affect the format and contents of diagnostic
 messages written to standard error.  Determines the
       location  of  message  catalogues  for  the  processing of
       LC_MESSAGES.
