uname

So, uname is a special version of the uname command that gives you some neat options to play with. It supports several flags like -a, -s, -r, -n, -v, and -m. Pretty cool, right?

How to Use uname

The basic usage goes like this:

Usage: uname [options]

Options You Can Use

• -s: Print the kernel name


• -v: Print the kernel version


• -r: Print the kernel release


• -n: Print the network node hostname


• -m: Print the machine hardware name


• -a: Print all of the above options!

If you don’t add any options, it will just act like you typed uname -s.

Coding with uname

If you're coding, you might need to include a few headers at the top of your file. Here’s what you should add:

#include <unistd.h>

#include <sys/utsname.h>

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

A Quick Look at What Happens in Code

Your main function could look something like this:

int main(int argc, char *argv[]) {

    // Declare your flags and other variables here...

n}

If there are no options provided when running it, it'll just default to printing the system name.

Error Handling Made Easy

If someone tries to use an option that doesn't exist, it will show them how to use it properly by calling a function that prints usage info.
