comment Debian package bigger than the source files
If an answer was correct, you should select the checkmark next to it. That indicates the problem has been solved. If you solved it, but no answers provided were helpful, then you should write your own and select that.

If a .git path is entering your package, you should rewrite the packaging scripts to ignore any unexpected ".*" files.

comment Privileges for ifconfig
@vonbrand That's an old view of Unix systems. In modern Linux, UID 0's power is only traditional as far as function goes. Capabilities are the defining matter, so any user can be given all or portions of that power. Similarly, a system can have a root / UID 0 user with no special privileges.

comment Privileges for ifconfig
... but that doesn't answer if there's a way to run it without being root. The Linux capabilities model is the defining matter in that. While root is traditionally granted these rights, other processors or users can be blessed with capabilities such as through SELinux contexts or as demonstrated by Celada using setcap (being rather like making a executable setuid, but for capbilities)

comment How to track traffic tidal wave on Amazon EC2 instance?
Sounds like you might need a consultant if your load spikes almost instantly to far beyond what a machine can handle unless you're keeping systems on idle standby, have a static content failover, or are otherwise able to scale up almost instantly.

comment find command + enable Exit status to be diff then 0 when not match
The basic problem comes from redirecting stderr to /dev/null. If you're running this as a scripted job, you'd never be aware of any errors even if the script did find a file. You wouldn't be aware that it was perhaps missing files it couldn't access due to permissions issues such as directories that don't have read permissions set. Remove that and let the parent script discard stderr if it is appropriate.

comment How to stop every incoming traffic except from 1 ip, on an ubuntu server
An answer should provide an answer within itself and use links as supporting references. Your answer post doesn't provide any information without following links and one of the links is a Google search. In this particular case, a concrete answer to the question should have been posted.

comment find command + enable Exit status to be diff then 0 when not match
In this case, if find had an error it would print the result to /dev/null, return a non-zero exit, and then have that fixed to 0 by the test command.
