sysf

A minimalist system information fetcher for UNIX and Linux-based systems, written in C.

This project is created for deep-dive learning of low-level POSIX system calls.

Features

• No bloated libraries: Directly invokes <sys/utsname.h> for pure performance.
• Buffer-safe: Formats strings using snprintf to prevent any potential memory corruption.
• Type-safe: Properly manages return types and stream operations with fwrite.

Build and Run

To compile and execute:

gcc sysf.c -o sysf
./sysf

Output Example

OS Name:    Darwin
Version:    25.6.0
CPU Arch:   arm64
