Process-Hunter

A C program that retrieves detailed information about a running process in the operating system using the Process ID (PID). This program utilizes the Linux /proc filesystem to extract useful details such as process name, command-line arguments, state, parent process ID, memory usage, and executable path.

Features

• Process Name: Fetches the name of the process.
• Command-line Arguments: Retrieves the command-line arguments used to launch the process.
• Process State: Displays the current state of the process (e.g., running, sleeping).
• Parent Process ID (PPID): Fetches the parent process ID.
• Memory Usage: Displays the virtual memory size of the process.
• Number of Threads: Shows the number of threads used by the process.
• Executable Path: Gets the path to the executable of the running process.
• Error Handling: Gracefully handles errors such as invalid PID or file access issues.

Requirements

• C Compiler: gcc or compatible C compiler.
• Linux Operating System: This program is designed to work on Linux-based systems as it uses the /proc filesystem.

Installation

To build and run the project on a Linux-based system:

1. Clone the repository:

git clone https://github.com/0xAminED/Process-Hunter.git
cd Process-Hunter

2. Compile the code:

gcc -o Process_Hunter Process_Hunter.c

3. Run the process scanner:

./Process_Hunter

Usage

The program requires the Process ID (PID) of the process whose details you want to retrieve.

Example

Enter Process ID (PID): 1234
Fetching information for PID: 1234
Process Name: bash
Command-line: /bin/bash -c sleep 100
=== Status ===
State: S (sleeping)
PPid: 1000
Threads: 1
VmSize: 12456 kB
Executable Path: /usr/bin/bash

Explanation of Output

• Process Name: Displays the name of the process.
• Command-line: Shows the full command line used to start the process.
• State: The current state of the process (e.g., sleeping, running).
• Parent Process ID (PPid): The PID of the parent process that spawned the current process.
• Threads: Displays The number of threads associated with the process.
• VmSize: The virtual memory size allocated to the process.
• Executable Path: The full path to the executable file running the process.
