The Polyglot Scripts

Conventional scripting practices remain tethered to platform-specific interpreters, forcing developers to maintain redundant codebases like batch, PowerShell, and POSIX shell. This poses a significant problem when there is a requirement to unify all of them under a single common command especially seen in continuous integration (CI) implementations. Moreover, the situation worsens considerably for cross-platform implementations where the initializer must locate not only the correct interpreter but also OS-specific and architecture-specific executables before running them. Unlike programming languages, there are requirements where these scripts run first to initialize the environment, such as setting up a programming language interpreter. Therefore, there is a need for these initializer unifications. This research project introduces the Polyglot Scripts, a novel unification layer that enables a single unified script file to execute seamlessly across Windows OS, UNIX, and UNIX-like OSes without modification. It is done by exploiting the syntactic intersections and conditional parser directives among the shell scripts, achieving true write-once-run-anywhere semantics at the shell level. Beyond cross-platform utility, these scripts simplify the user command into a single launch file, permit on-site editing instead of compiling|cross-compiling every time, and remain adaptive across all operating systems' technological advancements. For automation engineers/developers, this project produces a set of usable Polyglot Scripts to quickly eliminate environment anxiety, shrink maintenance overhead, and deliver future-proof workflow portability without increasing the learning curve.
