README

        
execfuse is a implement FUSE filesystems using a bunch of scripts.

Consider it as a "shell FUSE binding".

For each FUSE call (except of ones that deals with file descriptors)

execfuse calls your script. For opening files it provides a bit higher

level abstraction: "read_file" script is called when file should be read

and "write_file" is called when file should be saved.

Example:

    $ mkdir -p m

    $ ./execfuse examples/xmp m

    $ ls -l m/bin/sh

    lrwxrwxrwx 1 root root 4 Mar 26 00:26 m/bin/sh -> bash

    (executes "examples/xmp/readlink /bin/bash" for this)

    $ ls m/etc/iproute2/

    ematch_map  group  rt_dsfield  rt_protos  rt_realms  rt_scopes	rt_tables

    (executes "exampels/xmp/readdir /etc/iproute" for this)

    $ m/bin/echo qqq

    qqq

    $ mkdir -p m/tmp/1/2/3

    $ echo 12345 > m/tmp/12345

    (executes "exampels/xmp/write_file /tmp/12345" with content piped to stdin)

    $ rm -Rf m/tmp/1*

    $ fusermount -u m

Limitations:

* Each file must fit in memory, can't write/read part of file

* Slow by design

* Limited error handling, especially for writing files

* Modifications to files are visible only after file closing

Filesystem examples:

* `examples/xmp` - try to be fusexmp_fh

* `examples/hello` - very simple demo filesystem

* `examples/video_frames` - extract frames from video as `*.ppm` files and enumerate keyframes (using ffmpeg)
