         unalias discards aliases that match (filename substitution) pattern.
         All aliases can be removed by `unalias *'.
  
-    ksh
-        alias with no arguments prints the list of aliases in the form
-        name=value on standard output. An alias is defined for each name whose
-        value is specified. A trailing space in value causes the next word to
-        be checked for alias substitution. The -t flag is used to set and list
-        tracked aliases. The value of a tracked alias is the full pathname
-        corresponding to the specified name. The value becomes undefined when
-        the value of PATH is reset but the aliases remained tracked. Without
-        the -t flag, for each name in the argument list for which no value is
-        specified, the name and value of the alias is printed. The -x flag is
-        used to set or print exported aliases. An exported alias is defined for
-        scripts invoked by name. The exit status is non-zero if a name is
-        specified, but no value, and no alias has been defined for the name.
- 
- 
-        The aliass specified by the list of names can be removed from the alias
-        list with unalias.

     ksh93
         alias creates or redefines alias definitions or writes the existing
