A safe alternative for
rm with minimum difference
Ports: See #ports
What is this?
rm-protection is a safe alternative for removing files. It works exactly the same as
rm (in fact it passes arguments to
rm almost untouched). The only difference is that it refuses to proceed if a
.*.rm-protection file is found and you failed to answer a question.
Why are you here?
I watched GitLab engineers trying to recover their production database live on YouTube.
Suddenly an idea struck me: What if
rm prompted to ask "Which server are you on?" or "Which database are you trying to delete?"?
The disaster could have been avoided.
Install from PyPi and make an alias for
pip install rm-protectionand optionally,
alias rm="rm-p"for your daily user and root (so that it works for
Protect your files using
protect. If you want to protect everything inside,
How does it work?
It consists of two utilities:
protect. The latter one is to help you protect files.
For example, you have a file called
important_file and it is
rm-p will recognize that
important_file is protected and prompt to ask you a question stored in
rm-p will only proceed if you get the answer right.
See it in action:
It will also prevent you from deleting a directory with
protected file(s) inside.

Comparison with alternative methods
|Methods||Can be used as "rm"?||Protect Specific Files||Flexibility||Additional Files|
|rm -i||Yes||No or Somehow||High|
|rm-protection||Yes||Yes||High||One for each|
Why don't you just use XXX?
rm-protection aims at providing maximum protection and flexibility while making minimum impact on daily operation.
rm -i can be very annoying,
trash-cli is a bit complex (imagine you have a habit of emptying the trash without a second thought, or imagine you are trying to free up spaces on a budget vm).
Safe-rm is inconvenient when you really need to delete something (you have to edit the configuration file).
rm-protection asks you a question set by you. You are fully covered when removing files (you won't accidentally empty the trash with
| yes with
rm -i), and you can quickly remove files (without editing any configuration files).
How to contribute?
Pull requests and issues are all welcome! Or tell others about this, so you can even
protect the files you send to others!
Actually I don't care if people are using my implementation at all. I just think this kind of mechanism can be great -- using a
.rm-protection file that asks questions.
If the community welcomes this mechanism, it will soon be ported/rewritten in every platform or languages, or even be implemented in the GNU coreutils. Then you can even get some default protections shipped with distributions and packages.
So if you agree on this mechanism, please share with others!
