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

<code>free -m -h</code>

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

Example output might look like:
<pre>
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
</pre>

== Hard Drive Space Info ==
To check disk space usage for mounted filesystems:

<code>df -h</code>

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

Example output:
<pre>
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 100G 25G 75G 25% /
</pre>

== CPU Info ==
To display detailed information about the CPU:

<code>lscpu</code>

This shows architecture, number of cores, clock speed, etc. Example output snippet:
<pre>
Architecture: x86_64
CPU(s): 4
Model name: Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz
CPU MHz: 2400.000
</pre>

For a more concise CPU summary, use:

<code>cat /proc/cpuinfo</code>

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

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

<code>sudo dmidecode -t baseboard</code>

* Requires sudo privileges.
* Example output:
<pre>
Base Board Information
Manufacturer: Dell Inc.
Product Name: 0F6X5P
Version: A00
</pre>

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

<code>sudo dmidecode -t system</code>

== 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:

<code>lsblk</code>

Example:
<pre>
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]
</pre>

=== GPU/Graphics Card Info ===
To check graphics hardware:

<code>lspci | grep -i vga</code>

Example:
<pre>
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07)
</pre>

For detailed driver info, use:

<code>glxinfo | grep "OpenGL renderer"</code>

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

=== Network Hardware ===
List network interfaces and hardware:

<code>lshw -C network</code>

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

=== Full Hardware Summary ===
For a complete hardware overview in one go:

<code>sudo lshw</code>

* 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.
