A FUSE mount that only permits safe characters in the file names

Project description

# safemount

We have to jump through multiple hoops in shell scripts to ensure that our scripts handle special characters such as space, hyphen etc. properly. A number of security vulnerabilities exist because of mishandling of these characters.

However, these special characters, while important for GUI are not a necessity for command line. The idea of this library is to provide a FUSE filesystem that mounts a given directory under a mount point such that all the special characters are URL encoded. We include - in the list of characters that are encoded. Further, we also remove . and .. from the directory listing.

With this, the shell scripts can assume that none of the directory or file names contain special characters.

The usage is as follows:

` python3 -m pip install fusepy python3 -m safemount ./mydir ./mntpoint `
