Make Self-Extracting Archives with makeself.sh

When making your custom scripts or software available to someone else, it’s a good idea to make that content as easy to extract and install as possible. You could just create a compressed archive, but then the end user has to manually extract the archive and decide where to place the files. Another option is creating packages (.deb, .rpm, etc) for the user to install, but then you’re more locked into a specific distribution. A solution that I like to use is to create a self-extracting archive file with the makeself.sh script. This type of archive can be treated as a shell script and will extract itself, running a scripted set of installation tasks when it’s executed. The reason this works is that the archive is essentially a binary payload with a script stub at the beginning. This stub handles the archive verification and extraction process and then runs any predefined commands via a script specified at the time the archive is created. This model offers you a lot of flexibility, and can be used not only for installing scripts and software but also for things like documentation.
