    Warren Teitelman originally wrote DWIM to fix his typos and spelling errors, so it was somewhat idiosyncratic to his style, and would often make hash of anyone else’s typos if they were stylistically different. Some victims of DWIM thus claimed that the acronym stood for ‘Damn Warren’s Infernal Machine!’.

    In one notorious incident, Warren added a DWIM feature to the command interpreter used at Xerox PARC. One day another hacker there typed delete *$ to free up some disk space. (The editor there named backup files by appending $ to the original file name, so he was trying to delete any backup files left over from old editing sessions.) It happened that there weren’t any editor backup files, so DWIM helpfully reported *$ not found, assuming you meant ‘delete *’. It then started to delete all the files on the disk! The hacker managed to stop it with a Vulcan nerve pinch after only a half dozen or so files were lost.

    The disgruntled victim later said he had been sorely tempted to go to Warren’s office, tie Warren down in his chair in front of his workstation, and then type delete *$ twice.

      I had no idea git auto-correct existed, and now that I do I have zero plans to use it, for exactly this reason.

      Why can’t people leave a version control system alone to do its version control thing only?

      1. 1

        because it is easier to create well integrated and use friendly software like this :)

        This is, essentially, my primary use case for thefuck. I don’t think I’d like it to fire automatically, though.

          If the correction is ambiguous it aborts. Using it for years and never completed anything wrong.
