Introduction

System programming involves developing software that directly interacts with the underlying hardware and operating system. In this repository, we explore Linux system calls and commands implemented in C to gain a deeper understanding of how operating systems function at a low level.

Features

• Implemented Linux commands:

• ls: List directory contents.

• cp: Copy files

• rmdir: Remove empty directories.

• rm: Remove files

• cat: Concatenate files and print on the standard output.

• grep: Print lines matching a pattern.

• pwd: Print name of current/working directory.

• echo: Display a line of text.

• nano: Terminal-based text editor

• touch: Create new empty files.

• wc: Count words, lines, and characters in files

• mkdir: Creates a new directory.

• date: Display the current date and time

• sleep: Pause the execution of a program for a specified number of seconds.

• chmod: Changes the permissions of a file or directory to the specified mode.

• uname: Get basic information about the OS

• clear: Clear terminal
