Check System Layout

After setting up a new Linux machine, at least you need to understand the layout. Including the CPU, memory, disk, and network. You can check the server layout by running:

Green="\033[32m"
Blue="\033[36m"
Font="\033[0m"
OK="${Green}[  OK  ]${Font}"
function print() {
  echo -e "${OK} ${Blue} $1 ${Font}"
}

print "OS information"
sudo lsb_release -a
print "OS install date"
stat -c %w /
print "Secure Boot status"
sudo mokutil --sb-state
print "Root file system"
sudo df -Th /
print "Boot mode"
if [ -d /sys/firmware/efi ]; then echo "Boot mode: UEFI"; else echo "Boot mode: Legacy"; fi
print "CPU information"
sudo lscpu
print "PCIE information"
sudo lspci
print "USB information"
sudo lsusb
print "Disk layout"
sudo lsblk
print "All disks information"
sudo fdisk -l
print "Disk usage"
sudo df -Th
print "Memory information"
sudo free -h
print "Network information"
sudo ip link show
print "Firewall status"
sudo ufw status
print "Network location"
curl https://ipinfo.io

Find OS Installation Date

To find the OS install time on AnduinOS, you can use the stat command:

stat /

And you can filter the Birth field to get the OS install time:

stat / | grep Birth

Or even simpler, you can run:

stat -c %w /

That's it!

Check Secure Boot Status

To check the Secure Boot status on AnduinOS, you can use the mokutil command:

sudo mokutil --sb-state

You can also check the signature database status:

sudo mkutil --list-enrolled

Check Root File System

To check the root file system on AnduinOS, you can use the df command:

sudo df -Th /

Check Boot Mode

To check the boot mode on AnduinOS, you can use the following command:

if [ -d /sys/firmware/efi ]; then echo "Boot mode: UEFI"; else echo "Boot mode: Legacy"; fi

Check CPU Information

To check the CPU information on AnduinOS, you can use the lscpu command:

sudo lscpu

Check PCIE devices

To check the PCIE devices on AnduinOS, you can use the lspci command:

sudo lspci

Check USB devices

To check the USB devices on AnduinOS, you can use the lsusb command:

sudo lsusb

Check Disk Layout

To check the disk layout on AnduinOS, you can use the lsblk command:

sudo lsblk

Which will output all mounted disks and partitions.

To also check all available disks, you can use the fdisk command:

sudo fdisk -l

To know the file system and disk usage, you can use the df command:

sudo df -Th

You can also use df to check a specific folder:

sudo df -Th /path/to/folder

Check Memory Information

To check the memory information on AnduinOS, you can use the free command:

sudo free -h

To check memory usage in real-time, you can use the watch command:

watch -n 1 free -h

To check all processes and their memory usage, you can use the top command:

top -o %MEM

Check Network Information

By default, AnduinOS use NetworkManager to manage network connections.

To check the NetworkManager status, you can use the systemctl command:

sudo systemctl status NetworkManager

To edit the NetworkManager configuration, you can use the nmcli command:

sudo nmcli connection edit connection_name

Or even easier, simply use gnome-control-center:

To check the network information on AnduinOS, you can use the ip command:

sudo ip link show

Check Firewall Status

To check the firewall status on AnduinOS, you can use the ufw command:

sudo ufw status

To allow a specific port, you can use the ufw command:

sudo ufw allow 80

To view all rules, you can use the ufw command:

sudo ufw status numbered

To remove a specific rule, you can use the ufw command:

sudo ufw delete 1

Check Network Location

To check the network location on AnduinOS, you can use the ipinfo command:

curl https://ipinfo.io
