Associate SH scripts to Windows bash

Question

How can I associate all .sh files to new BASH included in Windows 10 Anniversary update?

I have tried associating .sh file using default system prompt to C:\Windows\System32\bash.exe but it just flashes console window with no result.

Answer 1

The problem is that BASH uses Unix-like paths and Windows gives DOS paths. So you need to redirect DOS path to Unix path.

My solution

It is more like hack than a real solution. USE AT YOUR OWN RISK

Write tiny C# console app to redirect paths

string[] splt = args[0].Split(':');
string exe = Environment.GetFolderPath(Environment.SpecialFolder.System) + "\\bash.exe";
string arguments = "/mnt/" + splt[0].ToLower() + splt[1].Replace('\\', '/');

using (Process process = new Process())
{
    process.StartInfo.FileName = exe;
    process.StartInfo.Arguments = arguments;

    process.Start();
    process.WaitForExit();

    return process.ExitCode;
}

And then you associate .sh files with this C# app

Dirty but works

Answer 2

It's also possible to do with just a batch file:

@echo off

REM Get the full qualified path for the first argument
SET fullpath=%~f1

REM Get the drive letter and convert it to lowercase
SET drive=%fullpath:~0,1%
FOR %%i IN ("A=a" "B=b" "C=c" "D=d" "E=e" "F=f" "G=g" "H=h" "I=i" "J=j" "K=k" "L=l" "M=m" "N=n" "O=o" "P=p" "Q=q" "R=r" "S=s" "T=t" "U=u" "V=v" "W=w" "X=x" "Y=y" "Z=z") DO CALL SET drive=%%drive:%%~i%%

REM Replace \ with /
SET relpath=%fullpath:~3%
SET relpath=%relpath:\=/%

C:\Windows\System32\bash.exe --login "/mnt/%drive%/%relpath%"

Now just use Open with... (and remember to check Always use this app to open .sh files) to associate the sh files with this batch file.

EDIT: included --login argument for bash.exe to set all the appropriate linux specific environment variables (such as $PATH)

The equivalent Vbscript method (for PSSGCSim's C# code) would be:

If WScript.arguments.count <> 0 And LCase(Right(WScript.Arguments(0), 3)) = ".sh" Then
    Dim WshShell: Set WshShell = WScript.CreateObject("Wscript.Shell")
    strSHfile = WScript.Arguments(0)
    MyArr = Split(strSHfile, ":")
    strSHfile = "/mnt/" & LCase(MyArr(0)) & MyArr(1)
    strSHfile = Replace(strSHfile,"\","/")
    WshShell.Run "%systemroot%\system32\bash.exe " & """" & sSHfile  & """",,True
    Set WshShell = Nothing
End If

And the file association REG file is here:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.sh]
@="shfile"

[HKEY_CLASSES_ROOT\shfile]
@="SH Script File"

[HKEY_CLASSES_ROOT\shfile\shell\open\command]
@="wscript.exe \"D:\\Scripts\\bash.vbs\" \"%1\""

To make it run .SH files from network, you need to alter the script.

This works fine with MinGW (I personally prefer one bundled with a SmartGit):

    ftype bashfile="C:\Program Files\SmartGit\git\bin\bash.exe" "%1" %*
    assoc .sh=bashfile

If running from the batch script '%' -> '%%':

    ftype bashfile="C:\Program Files\SmartGit\git\bin\bash.exe" "%%1" %%*
    assoc .sh=bashfile

Answer 5

Since Windows 10 still didn't provide this feature (Nor drag-over to .sh) by default, I've decided to make a registry key that does just that;

You will be able to open an .sh file correctly after associating it to bash.exe; in addition, you can drag files to the .sh script to pass them as parameters.

You can download the key here:

http://www.mediafire.com/file/8lqd1v693uj1g6t/ShellBashScriptOpen_v7.rar

The key also enables the option to run the script in elevated mode (right click option - both windows admin and Linux superuser), while an extra (optional) key enables right click > edit with nano

Remember you have to have set bash.exe as default program to open .sh files to apply these changes (the executable path is C:/Windows/System32/bash.exe)

The main registry key executes the following script (being a reg key, remember \" becomes ", \$ becomes $, \\ becomes \ and %% becomes %):

#This makes bash.exe silently execute the command between quotes (whole code)
"%SYSTEMROOT%\System32\bash.exe" -c "

#Parses the dragged file paths from Windows paths to unix paths
path_param=\$(echo \"%*\" | sed 's/[[:space:]]\\([A-Z]:\\)/\\n\\1/g' | sed 's/[A-Z]:/\\/mnt\\/\\L&/g' | tr '\\\\' '\\/'\');
mapfile -t path_param <<< \"\$path_param\";
path_param=(\"\${path_param[@]//:}\");

#Same, but with the .sh script path
path_exec=\$(echo \"%l\" | sed 's/[[:space:]]\\([A-Z]:\\)/\\n\\1/g' | sed 's/[A-Z]:/\\/mnt\\/\\L&/g' | tr '\\\\' '\\/'\');
path_exec=\"\${path_exec//:}\";

#Removes the wole path (leaving only the file name) if the parameters are in the same directory of the script
if [[ \"\${path_param%%\\/*}\" -ef \"\${path_exec%%\\/*}\" ]];
    then path_param=(\"\${path_param[@]/#\${path_param%%\\/*}\\/}\");
fi;

#Sets working directory to the folder where the script is located
cd \"\${path_exec%%\\/*}\";

#Executes script with or without parameters
if [[ \$path_param == \"\" ]];
    then \"\$path_exec\";
    else \"\$path_exec\" \"\${path_param[@]/#\${path_exec%%\\/*}\\/}\";
fi;

#Leaves WSL console open after the .sh script finishes executing
cd ~; bash; "
