fair point, not in finance so didn't consider this.

However I find it extremely foolhardy that mistyping one character has an impact one thousand times greater, and that such an action can be performed without some kind of validation (whether explicitly via a confirmation, or implicitly in how the UX is designed).

Then again it is probably because of the typo risk that bankers get paid so much ...

`rm -rf` vs `rm -ri` could have that sort of impact. Or `sleep 1; shutdown -r now` vs `sleep 1h; shutdown -r now` to reboot the production server.

I once deleted all my source code instead of backing it up to my floppy by doing "del ." while command.com was in wrong drive. (Should have done "del a:\."; two letters cost me a night of running an undelete program)

I like my Bash tools as much as the next HNer, but always think it's faster, safer, and more accurate to use a windowed gui for moving or deleting important files and folders.
