The author experiments with the command `rm -rf /` on a new Linux server, revealing what remains after executing it as root. To run this command without the safeguard that prevents it from deleting critical files, the author uses the `--no-preserve-root` flag. After the command executes, many core utilities like `/bin/ls` and `/bin/cat` are gone, but a connection over SSH and existing bash builtins such as `echo` remain functional. With only the basic shell builtins available, the author creatively navigates the stripped-down environment. They demonstrate how to use `echo` and file globs to list files in `/dev`, `/proc`, `/run`, and `/sys`. To recreate a minimal version of the `ls` command, they define a function in bash, overcoming initial obstacles like existing aliases. The process continues with attempts to recover lost functionality, including using `cat`, and eventually leads to the idea of downloading the BusyBox utility, known for its multiple built-in commands. Challenges arise in executing newly created binaries since all original executables have been deleted. The author explores ways to identify executables still accessible through `/proc` links but finds that these are not valid. They mention kernel-level access as a potential solution and describe using sysrq magic to restart the system. The article concludes with a summary of a Redditor's method for recovering BusyBox, showcasing a step-by-step approach that involves creating a shared object to change file permissions and make the binary executable.
