.SH DESCRIPTION
SSHFS (Secure SHell FileSystem) is a file system for Linux (and other
operating systems with a FUSE implementation, such as Mac OS X or FreeBSD)
capable of operating on files on a remote computer using just a secure
shell login on the remote computer. On the local computer where the SSHFS
is mounted, the implementation makes use of the FUSE (Filesystem in
Userspace) kernel module. The practical effect of this is that the end user
can seamlessly interact with remote files being securely served over SSH
just as if they were local files on his/her computer. On the remote
computer the SFTP subsystem of SSH is used.
.PP
If \fIhost\fP is a numeric IPv6 address, it needs to be enclosed in
square brackets.
