Hi, Is unionfs a solution? https://en.wikipedia.org/wiki/UnionFS It layers filesystems. so you can create an upper layer, write the file and remove the layer. (So the modified file disappears). Regards Peter On Wed, Aug 26, 2015 at 2:12 AM, Sean Crosby <richardnixonshead@gmail.com> wrote:
I have a need for a way for a regular user (i.e. non root) to "override" a file on a filesystem with one of their own, but just for the lifetime of a script.
I'll give you an example.
One of my users runs a program which is distributed in a package (i.e. not changeable by them). That program is looking for a file, /path1/file1. My user would like to change this file to a different version of the file in different scripts.
I'm not aware of one, but is there a way to redirect file open calls for /path1/file1 to /path2/file2 in a script? It only has to be for file open/read calls, and not write. The /path1 filesystem is not writeable by the user.
Is there maybe a FUSE filesystem which will allow this, or something else?
Cheers, Sean
