The difference being that text editors are designed to show text, so non printing characters, new lines, control chars, invalid utf-8 code units and so on are not required to be handled safely. Generally speaking, then " binary" in binary editor doesn't refer to the base two, it actually is the antonym of " text editor". It is true that a binary editor should let you handle bytes in binary, but as you can see the base 2 is too small to give compact numerals. Your file should be returned to illegible gibberish, which you can save back out with :wq.Ī funny thing I just noticed: OS X binaries all start with the same 4 bytes which, in hex, spell out the phrase “cafe babe”. To do this, you run things through xxd again, but this time with the -r option: When you are done, you’ll want to convert things back into their binary format before saving. The ASCII representation is listed to the right, though editing this region will not affect the hex portion of the file. At this point, you can view or edit any of the hex data. This sends the entire contents of the opened document to xxd and loads in the result. To convert a file to hex dump representation, just load your file in vi and type the following: To do this, you just filter the file’s contents through the xxd hex dump utility, a trick that can be accomplished right within the vi/vim interface. If you’ve ever wanted to examine or edit a binary file in your favorite text editor, there’s an easy way to simulate a vi hex mode.
