booze

FUSE bindings for bash.

If you, like me, have ever had the desire to create a FUSE filesystem from a shell script, this may be just the thing for you.

booze compiles to a shared library (booze.so) that you can load into bash via its enable -f feature. It adds a new builtin to bash, booze, that mounts a FUSE filesystem and shuffles data back and forth between libfuse and bash functions in your script.

Its help text gives a basic description of how to use it:

booze: booze [-df] FN_ASSOC MOUNTPOINT
    Mount a booze filesystem at MOUNTPOINT using functions in FN_ASSOC.

    Options:
      -d: debug mode (implies -f)
      -f: run in foreground

    FN_ASSOC must be an associative array.  Any keys it contains that match
    one of the following FUSE operation names will cause that FUSE operation
    to be implemented by the bash function named by the value corresponding
    to the key:

        getattr
        access
        readlink
        readdir
        mknod
        mkdir
        unlink
        rmdir
        symlink
        rename
        link
        chmod
        chown
        truncate
        utimens
        open
        read
        write
        statfs
        release
        fsync
        fallocate
        setxattr
        getxattr
        listxattr
        removexattr

    If for any reason this doesn't seem like a good idea, the user is
    encouraged to drink until it does.

The files hello.sh (a simple "hello world"), passthrough.sh (sort of like a bind mount), and cowsayfs.sh (filenames through cowsay!) provide examples of functioning booze filesystems.
