Is this a bug? No. This is what happens. 1) an alias is declared in the subshell incurred by the `command substitution` 2) the alias builtin is executed, which prints out a declaration of the just-declared alias 3) the command substitution causes that which was just printed to be evaluated in the original shell 4) an alias is thus declared in the original shell As Lawrence advised in a different thread, such questions would be more appropriately posed at the help-bash list. -- Kerin Millar
