Batch .bat in 2026: Legacy Glue, Not a Personality
I still write .bat files in 2026. I also refuse to build an identity around them. That distinction— legacy glue vs personality —is the retrospective I wish someone had handed me earlier. Where .bat still appears (unironically) Vendor installers and unwrap scripts. Scheduled tasks authored a decade ago that still pay the bills. Tiny wrappers that set env vars and launch something else. Locked…
In 2026, <author> still writes .bat files and refuses to build an identity around them. These legacy scripts are often found in vendor installers, scheduled tasks, and tiny wrappers that set environment variables and launch other programs. <author> explains that using batch is unavoidable in Windows environments, ignoring aesthetics for operational requirements.
They emphasize that batch is no longer used for nontrivial logic like nested delayed expansion or JSON/HTTP workflows. It's also not ideal for team-shared automation when PowerShell is available. <author> advocates for writing clever batch only when it proves cleverness, not for personal amusement.
The author suggests that production should not be impressed by legacy glue patterns. Instead, they recommend using thin wrappers, explicit failures, and clear commenting. They advise against teaching batch as a first language for beginners and prefer PowerShell for new automation when possible.
When faced with a complex 400-line .bat file, the recommended approach is to identify entry points, track ERRORLEVEL, and extract the core functionality. The right move in 2026 often involves rewriting the core in PowerShell and creating a one-line .bat shim for legacy callers.
<author> concludes that legacy glue should be thin, labeled, and temporary-by-intent. Honoring this approach helps maintain Windows CLI practices without romanticizing the dialect. They emphasize that .bat in 2026 should be used like duct tape—proud when it holds and eager to replace when a better solution is available.
