fusermount -u mountpoint


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.


general options

-o opt,[opt...]

mount options

-h   --help

print help

-V   --version

print version

SSHFS options


equivalent to '-o port=PORT'


equivalent to '-o compression=yes'

-F ssh_configfile

specifies alternative ssh configuration file


equivalent to '-o ssh_protocol=1'

-o reconnect

reconnect to server

-o delay_connect

delay connection to server

-o sshfs_sync

synchronous writes

-o no_readahead

synchronous reads (no speculative readahead)

-o sync_readdir

synchronous readdir

-o sshfs_debug

print some debugging information

-o cache=BOOL

enable caching {yes,no} (default: yes)

-o cache_timeout=N

sets timeout for caches in seconds (default: 20)

-o cache_X_timeout=N

sets timeout for {stat,dir,link} cache

-o workaround=LIST

colon separated list of workarounds


no workarounds enabled


all workarounds enabled


fix renaming to existing file (default: off)


set nodelay tcp flag in ssh (default: off)


fix truncate for old servers (default: off)


fix buffer fillup bug in server (default: on)

-o idmap=TYPE

user/group ID mapping (default: none)


no translation of the ID space


only translate UID/GID of connecting user


translate UIDs/GIDs based upon the contents of uidfile and gidfile

-o uidfile=FILE

file containing username:uid mappings for idmap=file

-o gidfile=FILE

file containing groupname:gid mappings for idmap=file

-o nomap=TYPE

with idmap=file, how to handle missing mappings


don't do any re-mapping


return an error (default)

-o ssh_command=CMD

execute CMD instead of 'ssh'

-o ssh_protocol=N

ssh protocol to use (default: 2)

-o sftp_server=SERV

path to sftp server or subsystem (default: sftp)

-o directport=PORT

directly connect to PORT bypassing ssh -o slave communicate over stdin and stdout bypassing network

-o slave

communicate over stdin and stdout bypassing network

-o disable_hardlink

link(2) will return with errno set to ENOSYS.  Hard links don't currently work perfectly on sshfs, and this confuses some programs.  If that happens try disabling hard links with this option.

-o transform_symlinks

transform absolute symlinks to relative

-o follow_symlinks

follow symlinks on the server

-o no_check_root

don't check for existence of 'dir' on server

-o password_stdin

read password from stdin (only for pam_mount!)
