@github-actions[bot] commented on GitHub (Nov 23, 2025):

This issue might be a duplicate of existing issues. Please check:

  • #4599: Bash tool executes bash commands with cmd.exe (similar Windows shell execution issue)
  • #4379: Specific bash commands fail on Windows in Git Bash due to path re-mapping (Windows path handling)
  • #631: Windows Support (umbrella issue tracking all Windows problems)
  • #3479: Opencode bash tool spawn user commands using /bin/sh instead of bash (shell execution configuration)

The core issue appears to be related to how OpenCode spawns shell commands on Windows. When the AI tries to run shell commands on Windows, the spawn mechanism doesn't properly handle bash execution, particularly in WSL environments. Issues #4599 and #4379 describe similar problems where bash-specific commands fail on Windows due to improper shell handling.

Feel free to ignore if none of these address your specific case.

Asking opencode to run "Get-Command bash" directly gives

# Attempting to run the PowerShell cmdlet Get-Command to locate bash
$ Get-Command bash

Maybe my logic is messed up, but it should only be using bash if you have it in your path, idk why it fails but ill look into it for you

@rekram1-node as soon as Ubuntu wsl is installed on Windows it adds bash to path, imo shell should be configurable via config and maybe default to bash.exe from Git? claude code does that

or do you think defaulting to pwsh.exe or cmd.exe is a better option on Windows?
