Lately, I've been fooling aroung a lot with containers (docker) and virtual machines (Vagrant, VirtualBox, ...)
Lots of fun, but an unexpected consequence is that this created a lot of network bridges on my machine.
Thus, this output:
$ nmcli device status DEVICE TYPE STATE CONNECTION wlo1 wifi connected eduroam br-16841f4ab5b3 bridge connected br-16841f4ab5b3 br-6d277fff70af bridge connected br-6d277fff70af br-70abc1ec9d13 bridge connected br-70abc1ec9d13 br-7866640acd2f bridge connected br-7866640acd2f br-804db4145aa9 bridge connected br-804db4145aa9 br-989ab8bd5062 bridge connected br-989ab8bd5062 br-c393b3577508 bridge connected br-c393b3577508 br-c4e437f7076a bridge connected br-c4e437f7076a docker0 bridge connected docker0 virbr0 bridge connected virbr0
Those "br-" network interfaces are actually "bridges", used to connect an interface to another (see here for details).
Not really bad, but things are getting a bit crowded here, so I wanted to get rid of these at once. Here we go:
* To get only the names of the bridges:
$ nmcli device status | grep br- | awk -e '{print $1}'
br-16841f4ab5b3
br-6d277fff70af
br-70abc1ec9d13
br-7866640acd2f
br-804db4145aa9
br-989ab8bd5062
br-c393b3577508
br-c4e437f7076a
To remove them, the command is $ nmcli device delete <device>
So, as a oneliner:
$ for a in $(nmcli device status | grep br- | awk -e '{print $1}'); do nmcli device delete $a; done
Et voila !
