Today, I probably did the most stupid thing I have ever done on a Linux machine.
But let's start from the beginning, how the story unfold:
How not to use rustup's filesystem layout
rustup (by default) installs toolchains under
~/.rustup and all the important binaries are available under
Because I am having some trouble with getting Android Studio to reach my Rust toolchain, I tried to symlink all binaries in
/usr/bin. I knew this was going to be bad practice, I did it anyway. Only to realize that this hack did not work and now I wanted to revert my changes. But how? Easy right: Just remove all files beginning with
rust and any other file (read: symlink) from
~/.cargo/bin. Now one can see how bad my decision was to just 'try it out' and symlink all those files.
How not to remove files
For my 'fix' to work, I would obviously have to use
sudo. Thus, extra caution is necessary. But now see what I did:
What I wanted to do:
sudo rm cargo*
What I did instead:
sudo rm cargo *
So, basically, I just deleted everything in
Seriously, that's how I just broke my system.
What we learned
- NEVER 'try this out' when you modify your system level filesystem
- ALWAYS backup your system
- ALWAYS read your command twice if it combines
- even better: use something like
