I have a script that uses
at command. And sometimes I receiving emails as this one:
Date: Mon, 3 Jul 2017 14:18:00 +0300 (EEST) From: root <email@example.com> To: firstname.lastname@example.org Subject: Output from your job 173 Another app is currently holding the xtables lock. Perhaps you want to use the -w option?
Of course I would use this option to prevent messages like this, but first I want to know what is the meaning of this option. Unfortunately
-w option is not listed in
Does anyone know what exactly this option means?
