How to use the command macchina (with examples)

The ‘macchina’ command is a powerful tool that allows you to display information about your computer. It is especially useful for troubleshooting and system analysis. In this article, we will explore various use cases of the ‘macchina’ command and provide examples for each.

Use case 1: List out system information

Code:

macchina

Motivation: You can use this command to retrieve basic system information such as operating system details, hardware information, and network configurations. This can be helpful when diagnosing issues or providing information to support teams.

Explanation: Running the ‘macchina’ command without any additional arguments will list out the system information using the default settings or those specified in your configuration file.

Example output:

+------------------+---------+
|   Key            | Value   | 
+------------------+---------+
| Operating System | Linux   |
| Kernel Version   | 5.8.0   |
| Processor        | Intel   |
| Memory           | 8 GB    |
| Disk Space       | 256 GB  |
+------------------+---------+

Use case 2: Specify a custom configuration file path

Code:

macchina --config path/to/configuration_file

Motivation: In some cases, you may have a specific configuration file that contains additional system information or custom settings. By specifying a custom configuration file path, you can retrieve system information based on that configuration.

Explanation: By using the ‘–config’ argument followed by the path to your configuration file, the ‘macchina’ command will read the specified configuration file and display system information accordingly.

Example output:

+------------------+---------+
|   Key            | Value   | 
+------------------+---------+
| Operating System | Windows |
| Kernel Version   | 10.0.0  |
| Processor        | AMD     |
| Memory           | 16 GB   |
| Disk Space       | 512 GB  |
+------------------+---------+

Use case 3: List system information with additional details

Code:

macchina --long-uptime --long-shell --long-kernel

Motivation: Sometimes you may need more detailed information about specific aspects of your system. By using the ‘–long-’ arguments, you can retrieve extended information for uptime, shell, and kernel.

Explanation: The ‘–long-uptime’ argument will display additional details about the system’s uptime, such as the number of days since the last reboot. The ‘–long-shell’ argument will provide more in-depth information about the default shell, including the shell used, version, and default behavior. The ‘–long-kernel’ argument will show detailed kernel information, including the kernel version, release date, and build information.

Example output:

Uptime
+------------------------+----------+
|        Key             |  Value   |
+------------------------+----------+
| Days since last reboot |  7 days  |
+------------------------+----------+

Default Shell
+---------------+-----------+
|     Key       |   Value   |
+---------------+-----------+
| Shell         |  bash     |
| Version       |  5.1.4    |
| Default       |  true     |
+---------------+-----------+

Kernel
+---------------------------+---------------------+
|          Key              |        Value        |
+---------------------------+---------------------+
| Kernel Version            |      4.15.0-65      |
| Release Date              |   January 25, 2019  |
| Build Information         |      SMP, x86_64    |
+---------------------------+---------------------+

Use case 4: Check for errors/system failures

Code:

macchina --doctor

Motivation: If you encounter any errors or system failures while trying to fetch system information, it can be useful to run a diagnostic check. The ‘–doctor’ argument allows you to check for any errors or issues related to fetching system information.

Explanation: By using the ‘–doctor’ argument, the ‘macchina’ command will perform a diagnostic check and report any errors or system failures encountered during the process.

Example output:

+--------------+------------------------------------------------+
|   Level      | Message                                        |
+--------------+------------------------------------------------+
| Error        | Failed to retrieve network configuration        |
| Error        | Unable to detect hardware information           |
| Warning      | Configuration file not found                   |
+--------------+------------------------------------------------+

Use case 5: List original artists of all ASCII art

Code:

macchina --ascii-artists

Motivation: If you are a fan of ASCII art and want to know the original artists behind the ASCII art displayed by ‘macchina’, you can use the ‘–ascii-artists’ argument.

Explanation: Using the ‘–ascii-artists’ argument will list out the original artists of all the ASCII art displayed by ‘macchina’. This provides recognition for the artists’ work and allows you to explore more of their art if desired.

Example output:

+--------------+-------------------------------+
|    Artist    | ASCII Art                     |
+--------------+-------------------------------+
| John Doe     | Ascii art 1                   |
| Jane Smith   | Ascii art 2                   |
| David Johnson| Ascii art 3                   |
+--------------+-------------------------------+

Conclusion:

The ‘macchina’ command is a versatile tool for retrieving system information and troubleshooting your computer. By exploring and using its various arguments, you can gain insights into your system’s configuration, diagnose issues, and recognize the artists behind the ASCII art.
