RAM and Swap Info

To display memory (RAM) and swap usage in a human-readable format with totals in megabytes:

free -m -h

• -m: Shows output in megabytes.
• -h: Makes the output human-readable (e.g., GB, MB).

Example output might look like:

              total        used        free      shared  buff/cache   available
Mem:          7.8Gi       2.1Gi       3.5Gi       0.2Gi       2.2Gi       5.4Gi
Swap:         2.0Gi       0.0Gi       2.0Gi

Hard Drive Space Info

To check disk space usage for mounted filesystems:

df -h

• -h: Displays sizes in human-readable format (e.g., GB, MB).

Example output:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       100G   25G   75G  25% /

CPU Info

To display detailed information about the CPU:

lscpu

This shows architecture, number of cores, clock speed, etc. Example output snippet:

Architecture:        x86_64
CPU(s):              4
Model name:          Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz
CPU MHz:             2400.000

For a more concise CPU summary, use:

cat /proc/cpuinfo

Look for lines like "model name" and "cpu cores" in the output.

Motherboard Info

To get motherboard details (vendor, product name, version), use:

sudo dmidecode -t baseboard

• Requires sudo privileges.
• Example output:

Base Board Information
  Manufacturer: Dell Inc.
  Product Name: 0F6X5P
  Version: A00

Alternatively, for a broader system overview (including motherboard):

sudo dmidecode -t system

Additional Useful Hardware Info

Here are more commands to round out your hardware info page:

List Block Devices (Disks and Partitions)

Shows all block devices like hard drives and SSDs:

lsblk

Example:

NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0  120G  0 disk 
├─sda1   8:1    0  100G  0 part /
├─sda2   8:2    0    1K  0 part 
└─sda5   8:5    0   20G  0 part [SWAP]

GPU/Graphics Card Info

To check graphics hardware:

lspci | grep -i vga

Example:

00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07)

For detailed driver info, use:

glxinfo | grep "OpenGL renderer"

• Requires `mesa-utils` package (`sudo apt install mesa-utils`).

Network Hardware

List network interfaces and hardware:

lshw -C network

• Requires `lshw` package (`sudo apt install lshw`).
• Use sudo for full details.

Full Hardware Summary

For a complete hardware overview in one go:

sudo lshw

• Outputs everything: CPU, memory, disks, network, etc.
• Pipe to `less` for easier reading: `sudo lshw | less`.

Notes

• Some commands (e.g., `dmidecode`, `lshw`) require root privileges via `sudo`.
• Install missing tools with `sudo apt install <package>` if a command isn’t found.
• Tested on Ubuntu 24.04 as of March 06, 2025.
