The simplest and the fastes way to find your IP address in Linux Mint is to run the following command in linux terminal:
$ hostname -I
But this is an example, how to find your IP address in internal network. In case you are looking for an external IP address (the address you have in internet), you should run a command:
$ curl ifconfig.me
or
$ curl ident.me
In standard Devuan Linux installation command nmcli is included, but we have hostname command and can easily use is:
$ hostname -I
output:
192.168.0.103
In order to install japanese language keyboard layout in Elementary OS, use fcitx, but during installation choose "japanese language" instead of "chinese language". Keep in mind, that under Freya, nor ibus, nor SCIM is working properly.
First, you have to add fcitx repository:
$ sudo add-apt-repository ppa:fcitx-team/nightly
Then update your sources:
$ sudo apt-get update
After that you can install fcitx and chinese input layout:
$ sudo apt-get install fcitx fcitx-config-gtk fcitx-sunpinyin fcitx-module-cloudpinyin fcitx-chewing fcitx-table-all
Shutdown delay in Devuan Linux is made the same way as shutdown delay in other Linux distros. The only thing you have to do is to run "shutdown" comman with proper parameters. This is very easy. For example this command will delay system shutdown for 20 minutes:
$ shutdown +20
In case you want to delay shutdown for 2 hours, you run:
$ shutdown +120
This is simple thing: just set a number of minutes.
You already know, that to shut down system immediately, you can run a following command in linux terminal:
$ shutdown now
System will shutdown immediately. Surely, it you want to shutdown and then reboot it, you will run:
$ shutdown -r now
But sometimes you have to plan your shutdown (corporate rules, system maintenance, parental control etc). In this case you have just to pospone system shutdown using proper parameters while running "shutdown" command.
Sometimes you need to lock system and don't let users to log in. One of the solutions is to schedule system shutdown and postpone it with a lock from new logins. It can happen in case you want to upgrade the system, but it's impossible to kick logged users from the system and you want just to let them finish their work and then do you work.
Just imagine you need to postpone shutdown for 20 minutes and let users know that system maintenance is coming. Let's start postponed shutdown with an announcement, what is going to happen:
$ shutdown +20 "System upgrade is coming. Thank you for your patience"
