I would like to use a bash shell script from the SendTo folder. When I put a shortcut to a batch or exe into theSendTo folder it shows up in the shell Send To context submenu, but when the shortcut is pointing at a shell script it doesn't.

The OS I'm testing this on is Win7 Home Premium SP1. The extension is .sh which has been associated with MinGW's bash.exe.

My shell script has a .sh extension and I've tried disassociated the .sh extension (I think that MinGW set it up initially, but that didn't work) using this utility and tried to reassociate it to bash using:

ftype ShellScript=c:\MinGW\msys\1.0\bin\bash.exe -c "'%1' %2"
assoc .sh=ShellScript

in an admin cmd shell. Though this works at a command prompt and the Explorer shell (via double click), it won't show up in the Send To menu and it won't accept a parameter by dragging a file on top of the script directly.

Does anyone know how I would do this?

    Does Explorer run the bash shell script if you double click the shortcut to the shell script? Is the shortcut just for the shell script or for bash parameterized with the shell script? – Werner Henze Jun 18 '13 at 9:50
  • what is the file extension of the script? have you established a file type association for that type? windows cannot process the bang line if it is present. which bash-for-windows are you using? – Frank Thomas Jun 18 '13 at 12:05
  • @FrankThomas: I've added the additional info you requested to the question. – Adrian Jun 18 '13 at 13:31
  • @WernerHenze: An attempt to drag a file over a link to the script causes a red circle with cross to appear. Attempting to put it directly over the script doesn't work either (says Move to *dir*), so I'm thinking that it's not taking parameters for some reason even though it is executed if double clicked on. Any idea why this would be so? – Adrian Jun 18 '13 at 13:49
  • I don't find the answer to Werner Henze's second question, so in the similar direction: Did you try to use c:\MinGW\msys\1.0\bin\bash.exe -c C:\Path\To\Your\Script.sh as the target for the shortcut in SendTo? – mpy Jun 24 '13 at 7:04

This will enable Drag & Drop to any script. You can place one of them in SendTo folder and use it afterwards.

Registry Export:

Windows Registry Editor Version 5.00







The hex part actually is "C:\cygwin\bin\bash.exe -c "source $0;read" %1 %*" which gets encoded in the export.

You probably will want to remove the read after testing, so you can write scripts that just perform a task without leaving an open window. If you need this for single scripts, you can always add it add their end.

Use assoc .ext=ShellFile after importing to link any file extension you want with this functionality. The DropHandler in this example works for Windows XP and Windows 7 (probably others too) and basically means "run the command, with all dropped filenames as arguments".

Use this as a script (echotest.ext) to test basic functionality:

echo $0 $*;
  • +1 for using source eliminating invocation of another shell and answering my side question about drag and drop. Unfortunately it is not the main question, so unfortunately you won't get the bounty. But thanks. I tried to figure this out without success. (Y) – Adrian Jun 24 '13 at 19:28
  • This will allow you to directly use shellscripts in the SendTo folder, instead of creating a link to bash.exe with the parameter of the script. I actually believe this answers your question, while the accepted answer provides a workaround. Not going to argue though :P – Squeezy Jun 24 '13 at 19:32
  • Oh, good to know. Thanks. Hmmm, not sure who to give the bounty to then. :( – Adrian Jun 24 '13 at 19:38
  • mpy, he solved your problem first. I just worked this out, out of curiosity. Also I can't stop using SendTo and Drag & Drop to scripts ever since, so that shall be my prize! – Squeezy Jun 24 '13 at 19:40
  • +1 also from me for source, this is really a good point. @Adrian: Now you know, why SU didn't let you award the bounty too fast. IMHO Squeezy's answer deserves the bounty, because his answer is more elegant; if you feel bad about that ;) you still can accept my answer (as it solved your problem, too), but I would also be fine with upvote only. – mpy Jun 24 '13 at 20:28

Here is how to pass an argument to a bash shell function via SendTo (or via drag & drop). As an example I used the builtin echo. Set the target for your link in the SendTo folder as follows:

C:\cygwin\bin\bash.exe -c "echo Argument: $0; read"

Here $0 stands for the first argument after the given command linea), i.e. the full filename of the file on which the sendto action was executed. read keeps the window open, so that you can read the message. (I tested this with cygwin's bash, but I think mingw's bash should work, too.)

In your case, the target should be

c:\MinGW\msys\1.0\bin\bash.exe -c "/path/to/your/script.sh $0; read"

Now your script can process the filename. But note, that the filename is passed to the script as the first argument, so inside the script the filename is referenced as $1.

Last, but not least here are two screenshots as a summary:

enter image description here

enter image description here

a) You quoted man bash:

-c string If the -c option is present, then commands are read from string. If there are arguments after the string, they are assigned to the positional parameters, starting with $0.

To understand that, use e.g. the following target line:

C:\cygwin\bin\bash.exe -c "echo This is $0; read" Foo Bar Baz

This will print This is Foo, while

C:\cygwin\bin\bash.exe -c "echo This is $2; read" Foo Bar Baz

will print This is Baz. So the "string" is everything between the apostrophes, and Foo Bar Baz are the arguments.

    Ahhh, that's what that meant. Makes sense now. Thank you. I'll award you the bounty as soon as SO will let me. (says that I can do it in 11 hours for some reason shrug) – Adrian Jun 24 '13 at 17:54

If Windows refuses to link to a .sh file, you could maybe try using a .bat file that invokes the .sh script.

If that doesn't work, you could also try to compile the .bat into .exe.
A quick google found :

Batch Compiler

  • I know that I can use a proxy bat or exe. I would like to know if it can be done without such a proxy. – Adrian Jun 24 '13 at 17:28

Try this updated version of the REG file (note I use 64-bit Windows 7; use System32 instead of SysWOW64 if you have 32-bit Win7, Vista, or XP):

Windows Registry Editor Version 5.00

@="Shell Script"




@="C:\\Windows\\SysWOW64\\NOTEPAD.EXE %1"


@="C:\\MinGW\\msys\\1.0\\bin\\bash.exe -c \"source $0;\" \"%1 %*\""


@="C:\\Windows\\SysWOW64\\NOTEPAD.EXE /p %1"


@="C:\\MinGW\\msys\\1.0\\bin\\bash.exe -c \"source $0;\" \"%1 %*\""





This will allow your shell scripts to be also run as Administrator just as any .bat file does.  In other words, it makes all shell scripts UAC compatible when using Windows Vista and Windows 7 or 8.
