Every interface has undo except the terminal — where you can do the most damage. oops fixes that.
The installer handles everything — downloads the binary, adds the shell hook, and sets up the backup directory. Just answer y/n.
~ $ rm -rf src/ ▲ rm -r ~/project/src ~ $ oops ✓ Undid: rm -r ~/project/src ↩ restored ~/project/src
oops intercepts destructive commands before they run and silently backs up the affected files. Non-destructive commands pass through with zero overhead.
| Command | What oops does | Undo |
|---|---|---|
| rm / rm -rf | Copies files to trash before deletion | restore |
| mv a b | Backs up the overwrite target | restore b |
| > file.txt | Snapshots file before redirect overwrites it | restore |
| sed -i | Copies file before in-place edit | restore |
| chmod / chown | Records original permissions | restore |
| git reset --hard | Creates a stash before reset | stash apply |
| git checkout . | Creates a stash | stash apply |
| git branch -D | Logs the branch SHA before deletion | recreate |
| git clean -fd | Stashes untracked files | stash apply |
One command. The installer walks you through each step with y/n prompts — binary, shell hook, and backup directory.
