- alganet 2y agoKind of. It can be read as a single binary, some supported systems will do that. In others, the executable is first parsed as a shell script. There's definitely more to it than a single binary.

- bux93 2y agoReminds me of a cool tool I once used, uudecode.com, which was a DOS binary that only used 7-bit characters and could decode uuencoded (base64 predecessor) files. Was useful for getting attachments through e-mail in the face of all kinds of filters.
