How to chmod +x a file in Windows, for use in Linux?

Question

I have a file that needs to be executable in Linux, which I'd do by using chmod +x when using Linux.

My problem is: this file is compiled in Windows, and it's a pain to have to open my Ubuntu VM to just chmod it.

Is there a tool, or a method in Windows to allow me to add the +x permission to the file, so it is executable upon receipt to a Linux machine?

I've tried searching SU and Google, but I'm only seeing irrelevant results about how chmod doesn't exist on Windows, and to use file permissions instead - but this isn't what I'm looking for.

Solution 1

The key phrase in your question is "executable upon receipt", and the answer depends on how it's being received. If you send a tarball, you can have some executable files in it. A single file could be mailed in uuencode format with begin 755 filename in the header. If you provide more details on what tools you have available on the sending side, we might be able to find a way to make it work.

Solution 2

chmod +x sets attribute in the filesystem and is not assiciated with the file itself. So, there is no way to do that you want.

Solution 3

git update-index --chmod=+x myfile.sh

prepending a script see here might be a workaround?

I thought of using a tar archive, but my problem is getting it to be +x in the first place. Basically, I do all of my development on a Windows machine. It's a project using Adobe AIR, and in that is a requirement to use the NativeProcess class. In doing so, an exe is launched on Windows, and the binary on Linux. It's that binary that needs to be +x.

Actually, it looks like an untar package is available for AIR. I could put the executable in a tar archive, then untar it on installation.

For tar, look at my old time favourite unxutils (Linux command as .exe's under Windows. No cygwin or similar required.)

That isn't entirely true as VCS (e.g. git) keeps track of execution rights.
