Adam Wallis 3651a31c5e Fixes: 659ecd0388 plugins: percol: Check for alias zz before unalias ... The original patch (659ecd0388) unaliases the percol alias, however, does not validate if the alias is already defined. This leads to the following message that is shown everytime a new bash session is spawned where this variable is not defined when the percol plugin is enabled. bash: unalias: zz: not found		2018-01-10 19:58:29 -05:00
