Windows Instructions to fix: `bash: gdu: command not found`

[Gabriel Staples]

In Windows, gdu must be run as gdu_windows_amd64.exe instead. Please make this obvious to others.

bash: ncdu: command not found

I figured it out, but this is to help:

1. Myself, later
2. Others

I am using gdu in Windows as a replacement for ncdu which I have used for years in Linux Ubuntu.

I installed gdu into Windows by running winget install gdu in the Git Bash terminal. I think you can also use the cmd prompt, but that's besides the point. It seems to have installed fine.

Problem

I closed and re-opened my Git Bash terminal, and when I run gdu I get this error:

$ gdu
bash: gdu: command not found

Solution

If you type gdu and press Tab to auto-complete the command, it expands out into gdu_windows_amd64.exe, meaning that is the command we should be running! Running that command (gdu_windows_amd64.exe) works fine.

Running which gdu_windows_amd64.exe shows that the executable is located in /c/Users/my_username/AppData/Local/Microsoft/WinGet/Packages/dundee.gdu_Microsoft.Winget.Source_8wekyb3d8bbwe/gdu_windows_amd64.exe.

So, create a ~/.bashrc file in Windows, at path /c/Users/my_username/.bashrc as specified in Git Bash in Windows, and add the following alias to the bottom of it:

alias gdu="gdu_windows_amd64.exe"

Now, close and re-open all Git Bash terminals, and you can now run either gdu or gdu_windows_amd64.exe!

Recommendation

In your main README, change this:

[Winget](https://github.com/microsoft/winget-pkgs/tree/master/manifests/d/dundee/gdu):

    winget install gdu

To this:

[Winget](https://github.com/microsoft/winget-pkgs/tree/master/manifests/d/dundee/gdu) (for Windows users):

    winget install gdu

Now, either run it as `gdu_windows_amd64.exe`, *or* add `alias gdu="gdu_windows_amd64.exe"` to the bottom of your `~/.bashrc` file when using the Git Bash terminal, and run it as `gdu`.
