Go as a scripting language in Linux
summary
Claim: Go can be a practical scripting language if specific problems are solved — go run refuses a shebang so exit codes and kernel-level execution break, ad‑hoc hacks like the Chism line (replace # with // and early shell exit) are brittle, and community tools such as go run (no space) fix exit status and interprocess execution but still prevent compiling the same source. The reliable solution registers an interpreter with binfmt_misc in Linux, which preserves argument passing, real exit codes and allows compilation to a regular Go binary.
