I just lately switched from a Home windows server 2016 to a FreeBSD Unix server. I wish to take a look at disk house on Unix command line. How do I in finding out disk house usage data the usage of the Unix command-line possibility?

Unix circle of relatives of working techniques be offering the next instructions to test disk house utilization as consistent with your wishes.

Take a look at disk house on Unix working gadget

Unix command to test disk house:

1. df command – Displays the quantity of disk house used and to be had on Unix report techniques.
2. du command – Show disk utilization statistic for every listing on Unix server.

Methods to show Unix disk utilization statistics

See disk utilization for all information within the present listing. Run:
du -a
To get the disk utilization of a listing tree and every of its subtrees for /house/vivek, input:
du /house/vivek
Alternatively, it’s imaginable to peer outout 1024-byte blocks if you happen to go the -k transfer, input:
du -k /house/vivek
Wish to see overall disk utilization of a listing tree? Check out:
du -s /house/vivek

248088	/house/vivek

One can summarize disk utilization for a selected listing as follows:
du -hs /house

1.4G	/house

Subsequent allow us to display title and dimension of all py (Python) information in a selected listing. Additionally show grand overall on the finish:
du -ch /house/vivek/challenge/mgt1.2/*.py

Getting lend a hand about du command

Check out working the next guy command or see on-line guy web page here:
guy du
whatis du

Methods to show unfastened disk house data on Unix

To view the quantity of unfastened house within the report gadget, check out df command:
df

Wish to display details about /jails/www/ report gadget in 1024-byte blocks layout, run:
df -k /jails/www/

Filesystem      1024-blocks    Used       Avail Capability  Fastened on
zroot/jails/www 10745194355 3152328 10742042027     0%    /jails/www

In a similar fashion, to turn details about /jails/www report gadget in MB blocks layout, input:
df -m /jails/www/

Filesystem      1M-blocks Used    Avail Capability  Fastened on
zroot/jails/www  10493353 3078 10490275     0%    /jails/www

How about GB blocks layout for /jails/www report gadget?, Check out:
df -g /jails/www/

Filesystem      1G-blocks Used Avail Capability  Fastened on
zroot/jails/www     10247    3 10244     0%    /jails/www

Show a grand overall

Go the -c possibility:
df -c
Some model of Unix working techniques can show output in human readable layout. In different phrases, Use unit suffixes: Byte, Kibibyte, Mebibyte, Gibibyte, Tebibyte and Pebibyte:
df -H
Pattern outputs:

Conclusion

You discovered find out how to see unfastened and used disk house in addition to disk utilization statistics on Unix techniques.

I prefer to use NetworkManager on my Ubuntu desktop, but currently, it is using networkd. As a result, I cannot set up or configure NetworkManager using GUI tools. Is there anyway to change netplan renderer from networkd to NetworkManager running on Ubuntu Linux? How can I change netplan renderer in Ubuntu Linux?

Ubuntu Linux changed the networking config, and it is done using YAML. Netplan is a utility for easily configuring networking on a Linux-based system. It supports both networkd and NetworkManager.

networkd is part of Systemd. In other word systemd-networkd used to manage network connections using Systemd. On the other hand NetworkManager is a GUI tool for configuring networking options.

You can tell Netplan to use NetworkManager and it is useful for Linux desktop or laptop users. By default all network devices get handled by systemd-networkd. Let us see how to change that on an Ubuntu Linux desktop.

Change netplan renderer from networkd to NetworkManager

The procedure is as follows:

1. Open the Terminal window app
2. Backup current config file using the cp command.
3. Type the following command to edit your netplan config file
4. Set renderer to NetworkManager
5. Save and close the file
6. Reboot the system

Let us see all commands in details.

How to change renderer from systemd-networkd NetworkManager

First view the config file using the cat command:
cat /etc/netplan/01-netcfg.yaml
Sample outputs:

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s31f6:
      dhcp4: yes

The above config tells of bringing up the Ethernet interface named enp0s31f6 via DHCP.

Network Manager as the backend for netplan

Network Manager strives for Network Connectivity, which “Just Works” for new Linux users. The machine should use the wired network connection when it’s plugged in but automatically switch to a wireless connection when the user unplugs it. Similarly, you can easily configure a VPN network and many other options. Edit the config file using a text editor such as nano command or vim command
sudo cp -v /etc/netplan/01-netcfg.yaml /root/
sudo vim /etc/netplan/01-netcfg.yaml
Update it as follows:

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
# Set and change netplan renderer to NetworkManager GUI tool 
network:
  version: 2
  renderer: NetworkManager

Save and close the file. You can reboot the Linux computer or apply change by typing the following command:
sudo netplan apply
The above command applies the current netplan configuration to a running system.

How do I use a GUI tool to configure networking?

Open the Activities (press the Super key on your keyboard) overview and start typing Settings.

Next click on Network:

Now you can edit or and set new IP address. Select IPv4 or IPv6. Type in the IP Address and Gateway, as well as the appropriate Netmask. In the DNS section, switch the Automatic switch to off. Enter the IP address of a DNS server you want to use and so on:

Conclusion

You just learned how to change netplan renderer and set it to GUI based Network Manager GUI tool. For more information, see this page here and here.
