This allow standard utilities (grep, sed, etc) to work directly on remote files. Since then, several implementations of ftpfs and <a href="SSHFS" title="SSHFS">sshfs</a> have appeared.

</p><p>The FUSE system was originally part of <i>AVFS</i> (<i>A Virtual Filesystem</i>), a filesystem implementation heavily influenced by the translator concept of the <a href="GNU_Hurd" title="GNU Hurd">GNU Hurd</a>.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> It superseded Linux Userland Filesystem, and provided a translational interface using <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">lufis</code> in libfuse1.

</p><p>FUSE was originally released under the terms of the <a href="GNU_General_Public_License" title="GNU General Public License">GNU General Public License</a> and the <a href="GNU_Lesser_General_Public_License" title="GNU Lesser General Public License">GNU Lesser General Public License</a>, later also reimplemented as part of the <a href="FreeBSD" title="FreeBSD">FreeBSD</a> base system<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> and released under the terms of <a href="BSD_licenses#2-clause" title="BSD licenses">Simplified BSD</a> license. An <a href="ISC_license" title="ISC license">ISC</a>-licensed re-implementation by Sylvestre Gallon was released in March 2013,<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> and incorporated into <a href="OpenBSD" title="OpenBSD">OpenBSD</a> in June 2013.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>

</p><p>The userspace side of FUSE, the <style data-mw-deduplicate="TemplateStyles:r886049734">

/* start https://en.wikipedia.org/ */

.mw-parser-output .monospaced{font-family:monospace,monospace}

/* end https://en.wikipedia.org/ */

</style><span class="monospaced">libfuse</span> library, generally followed the pace of Linux kernel development while maintaining "best effort" compatibility with BSD descendants. This is possible because the kernel FUSE reports its own "feature levels", or versions. The exception is the FUSE fork for macOS, OSXFUSE, which has too many differences for sharing a library.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> A break in libfuse history is libfuse3, which includes some incompatible improvements in the interface and performance, compared to the older libfuse2 now under maintenance mode.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup>

</p><p>As the kernel-userspace protocol of FUSE is versioned and public, a programmer can choose to use a different piece of code in place of <span class="monospaced">libfuse</span> and still communicate with the kernel's FUSE facilities. On the other hand, <span class="monospaced">libfuse</span> and its many ports provide a portable high-level interface that may be implemented on a system without a "FUSE" facility.

</p>

<div class="mw-heading mw-heading2"><h2 id="Operation_and_usage">Operation and usage</h2></div>

<p>To implement a new file system, a handler program linked to the supplied <code>libfuse</code> library needs to be written. The main purpose of this program is to specify how the file system is to respond to read/write/stat requests. The program is also used to <a href="Mount_(computing)" title="Mount (computing)">mount</a> the new file system. At the time the file system is mounted, the handler is registered with the kernel. If a user now issues read/write/stat requests for this newly mounted file system, the kernel forwards these IO-requests to the handler and then sends the handler's response back to the user.

</p>

<p>FUSE is particularly useful for writing <a href="Virtual_file_system" title="Virtual file system">virtual file systems</a>. Unlike traditional file systems that essentially work with data on mass storage, virtual filesystems don't actually store data themselves. They act as a view or translation of an existing file system or storage device.

</p><p>In principle, any resource available to a FUSE implementation can be exported as a file system.
