kill_app.sh

This script is used to quickly terminate running programs on Linux and macOS systems. Tested on FydeOS Linux Subsystem, macOS 10.15.7, and Debian 12. Current version v1.0

Features

• Allows users to input a process name and attempts to find and terminate that process
• If no exact match is found, displays potentially related processes
• Supports terminating processes directly by PID

Usage

CNB:

wget https://cnb.cool/SDCOM/shit/-/git/raw/main/script/kill_app.sh && sudo chmod +x ./kill_app.sh && sudo ./kill_app.sh

Github:

wget https://github.com/SDCOM-0415/shit/raw/refs/heads/main/script/kill_app.sh && sudo chmod +x ./kill_app.sh && sudo ./kill_app.sh

After running the script, follow the prompts to enter the process name to terminate. If no exact match is found, the script will list potentially related processes and allow you to enter a PID to terminate a specific process.

Notes

• This script uses the kill -9 command to force terminate processes, which may cause data loss or other issues
• Before terminating important processes, ensure all work has been saved
• When using this script on Linux systems, root privileges may be required to terminate certain system processes
