/dev/full

In Linux /dev/full or the always full device is a special file that always returns the error code <a href="/mediawiki/index.php?title=ENOSPC" class="mw-redirect" title="ENOSPC">ENOSPC</a> (meaning "No space left on device") on writing, and provides an infinite number of null characters to any process that reads from it (similar to /dev/zero). This device is usually used when testing the behaviour of a program when it encounters a "disk full" error. $ echo "Hello world" > /dev/full bash: echo: write error: No space left on device
