How do I save myself from myself?
* `rm -rf *`
* `git reset --hard` Before hitting the enter key?
* `kubectl delete ns` Stop! you are going to delete a lot of resources
* And many more!
Do you want to learn from other people's mistakes?
`shellfirm` will intercept any risky patterns and immediately prompt a small challenge that will double verify your action, think of it as a captcha for your terminal.
```bash
rm -rf /
#######################
# RISKY COMMAND FOUND #
#######################
* You are going to delete everything in the path.
Solve the challenge: 8 + 0 = ? (^C to cancel)
```
## How does it work?
`shellfirm` will evaluate all the shell commands behind the scenes.
If a risky pattern is detected, you will immediately get a prompt with the relevant warning to verify your command.
## Example
