I think sshfs is a command line ftp XDDD

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

usually I will log in with option -0 sshfs_sync to make the write option will be process immediately remotely

eg.  sshfs wahaha@kclin.com:/ test_point -o sshfs_sync

will mount the root file system in kclin.com to local test_point folder

To unmount the folder, we could use

fusermount -u test_point
