How to do something based on exit code of command? about just

[casey]

I suggest writing a bash recipe:

foo:
  #!/usr/bin/env bash
  some_command
  if [[ $? == 100 ]]; then
    do_something
  fi

@casey bash recipes aren't portable to Windows, and defeat the purpose of a justfile for me. Would you reconsider this issue?

@ajeetdsouza Can you use powershell? If you don't have bash, powershell is pretty reasonable.

set windows-shell := ["powershell.exe", "-NoLogo", "-Command"]

hello:
  Write-Host "Hello, world!"

I did consider using PowerShell / Python / Nushell, but that would mean yet another tool I have to reliably install in CI.

I'm currently using an xtask to avoid this, but I'd be willing to migrate if just provided a few more advanced features.

This is windows CI? I'm not familiar with what ships natively, but it might already have powershell.exe or pwsh.exe.

[ajeetdsouza]

I want CI to run on Windows / macOS / Linux uniformly, and PowerShell is not bundled with macOS / Linux.

Ahh, I see. Can you open a new issue with your specific use case? I'd have to see exactly what you're trying to do to see if there's a good way to do it.
