They are very simple to construct and deconstruct, although they aren’t known for being small. The PPM format is part of a family of graphics formats from the 1980s. I’ll use t2b for the first job and xxd for the second. This shows off both tools since the first job is generating an image file from data and the second one is processing an image file and writing out a new one.

The other script takes a file in the same format and cuts the color values within it by half. So there is a benefit to using the binary format. That’s not strictly cheating because it does make a larger file, as you’d expect. And second I ignored the format that uses ASCII instead of binary. First, I picked the PPM (Portable Pix Map) format which is very simple to create. These aren’t production scripts so they won’t be as hardened as they could be, but there is no reason they couldn’t be made as robust as you were willing to make them. I decided to write a few test scripts using bash to show how it all works. On the other hand, if you are creating a binary file from scratch, the t2b program has some advantages, too. You can convert the file to text, process it, and then roll it back to binary using one program.

If you are editing a binary file in a scripting language, xxd makes perfect sense. You issue commands to it that causes it to write an original hex file.īoth of these approaches have some merit. The t2b tool takes a much different approach. What xxd can even reverse itself so that it can rebuild a binary file from a hex dump it creates (something other tools can’t do). The xxd tool can actually do the same thing - although it is not as flexible. You might be familiar with tools like od or hexdump for producing readable representations of binary files. These tools take very different approaches.

You should be able to install xxd from your system repository.

You can find the code for t2b on GitHub including prebuilt binaries for many platforms. One answer is to use a tool like xxd or t2b (text-to-binary) to handle the details. However, if you are using some type of scripting language, binary file support might be a bit more difficult. About the worst thing you might have to deal with is attempts to fake line endings across Windows and Linux, but there’s usually a way to turn that off if it is on by default. If you ever need to write a binary file from a traditional language like C, it isn’t all that hard to do.
