NAME         top

       SSHFS - filesystem client based on ssh

SYNOPSIS         top

       sshfs [user@]host:[dir] mountpoint [options]

       @UNMOUNT_COMMAND@ mountpoint

DESCRIPTION         top

       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.

       If host is a numeric IPv6 address, it needs to be enclosed in
       square brackets.

              file containing username:uid mappings for idmap=file

              don't currently work perfectly on sshfs, and this confuses
              some programs.  If that happens try disabling hard links
              with this option.
