Mount a directory to another location and alter permission bits.

bindfs is a FUSE filesystem for mounting a directory to another location, similarly to mount --bind. The permissions inside the mountpoint can be altered using various rules.


Here are some examples of what bindfs can do for you:


Downloads and source

bindfs is available through the software repositories of many Linux distributions, as well as MacPorts on OS X. Check there first unless there is a specific new feature that you need.

Download the latest source tarball here: bindfs-1.17.0.tar.gz.

Compile & install: ./configure && make && sudo make install.

There is an extensive HowTo on Ubuntu Forums.


bindfs is developed and tested primarily on Linux with FUSE 2 and 3, but it has been reported to work reasonably well on Mac OS X with osxfuse and on FreeBSD with fuse4bsd.

All FUSE filesystems necessarily incur a performance penalty in CPU time and memory consumption. If all you need is to make a directory read-only then mount --bind -r is more efficient.

bindfs was initially developed in 2006. I consider the program fairly feature-complete but I’ll still gladly fix bugs and add some small features as people suggest them.
