README for KillReg Script

Overview

killreg is a Bash script designed for Unix-like operating systems to terminate processes that match a given pattern. It allows for an optional signal specification to control how the processes are terminated.

Usage

• Basic Command: ./killreg <PATTERN>
• With Signal: ./killreg [-SIGNAL] <PATTERN>

Arguments

• -SIGNAL: An optional signal to send to the matching processes, e.g., -9 for SIGKILL, -TERM for SIGTERM. Default is -TERM.
• PATTERN: A required argument. The script will terminate all processes that match this pattern.

Examples

• To terminate processes matching myapp: ./killreg myapp
• To forcibly terminate processes matching myapp: ./killreg -9 myapp

Requirements

• Bash shell
• Unix-like operating system
• User must have necessary permissions to terminate the targeted processes.

Error Handling

The script checks for:

• Minimum requirement of one argument.
• Correct format when two arguments are provided (first argument should start with a hyphen).

Note

Use this script with caution as terminating critical system processes can lead to system instability.
