System hangs script

After spending too long trying to debug my Endeavour OS which had ramdom
system hangs I decide to write a script to get me out of the problem
when it occurred.

I have written this for beginners and hopefully it will be easy to

This script will give you a graceful shutdown during a system hang.

You need to create conf file in /etc/sysctl.d

Just press Ctrl+Alt+T to bring up a Terminal
Run the command below to create the conf file

echo kernel.sysrq=1 | sudo tee -a /etc/sysctl.d/99-sysctl.conf

Also in the Terminal run the following command below to reload the conf
files  without rebooting the computer** su -c "sysctl –system" **You maybe
ask for your password.

We now need to create the mail script file
In the Terminal type** sudo nano /usr/local/bin/
Add the following to the** **and safe it.

# cat /usr/local/bin/

for c in r s u o; do
  echo $c > /proc/sysrq-trigger
  sleep 2

We need to make the script executable
In the Terminal type** sudo chmod +x /usr/local/bin/
We need to add the following to the /.bashrc file
If you are the zsh you will need  add the following to the /.zshrc file
Open the .bashrc In the Terminal type** sudo nano ~/.bashrc scroll 
to the bottom of the file add the following and save the file.

# Sysrq key combo for system hang
alias sysh='sudo /usr/local/bin/'

Finely the Terminal type source** ~/.bashrc or ~/.zshrc
You can now test the script by Ctrl+Alt+F4 which Opens TTY 
You will need to login once login type sysh and the system will graceful 
shutdown after about 2 seconds.

This all so works on any Arch base system.
