Subject: added error suppression to tree alias
X-Git-Url: https://source.supwisdom.com/gerrit/gitweb?a=commitdiff_plain;h=f0bceecb88f01a143c9d4df977c9db473e8618bb;p=common%2Fbash_it.git

added error suppression to tree alias

the $(which tree) check general.aliases would ouput an error if the
    command was not found. Added suppression of that error.
