I have a Ubuntu machine that is running a windows 7 VM. I am using VMware workstation 15 pro. My home directory is shared with the VM and is mapped as a network drive on the Windows guest.

I have a script that I want to run using Cygwin on Windows guest. On Linux the permissions are rwxr-xr-x. However, in Cygwin on the Windows guest the permissions are rw-r--r--. I am loosing my execute permission. From Cygwin if I chmod the file to add execute permission (eg: chmod u+x foo.sh) there is no change. How can I add execute permission in the windows guest? Is this an issue with the VMWare share, or is it an issue with network shares in general?

The shell script starts with #!, so by default cygwin should treat it as executable if this were a local file. According to the cygwin manual if this were an NFS share it should just work. I am not sure if the issue is that this looks like SMB, or if it is a deeper issue with the way VMWare shares files.

  • Are you using VMware shared folders or are you actually mounting your home directory as a network share (i.e. CIFS/SMB)?

    It seems that the mount has the permission for execution disabled. Has Cygwin has no mount capabilities you should check the "security" settings/policy of Windows

  • @jamesdlin It is a VMware shared folder. But on a windows guest it looks like a Windows/SMB network share, and I ticked the box to make it look like a network drive that is mounted on boot. I didn't actually set up a network share on the host.
