sftp - secure file transfer program
sftp [options] [user@]host[:dir[/]]
sftp [options] [user@]host[:file1 [file1 [file | dir2]]
The sftp utility is an interactive file transfer program with a user interface similar to ftp(1) that uses the ssh(1) command to create a secure connection to the server.
sftp implements the SSH File Transfer Protocol as defined in IETF draft-ietf-secsh-filexfer. There is no relationship between the protocol used by sftp and the FTP protocol (RFC959) provided by ftp(1).
The first usage format causes sftp to connect to the specified host and enter an interactive mode. If a username was provided then sftp tries to log in as the specified user. If a directory is provided then sftp tries to change the current directory on the server to the specified directory before entering the interactive mode.
The second usage format retrieves the specified file from the server and copies it to the specified target file or directory on the client. If a username is specified sftp tries to log in as the specified user.
The following options are supported:
Batch mode reads a series of commands from an input batchfile instead of stdin. Since it lacks user interaction, it should be used in conjunction with non-interactive authentication. sftp aborts if any of the following commands fail: get, rm, and lmkdir.
Specifies the size of the buffer that sftp uses when transferring files. Larger buffers require fewer round trips at the cost of higher memory consumption. The default is 32768 bytes.
Enables compression, using the -C flag in ssh(1).
Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).
Specifies an option to be directly passed to ssh(1).
-P sftp_server path
Executes the specified path as an sftp-server and uses a pipe, rather than an ssh connection, to communicate with it. This option can be useful in debugging the sftp client and server. The -P and -S options are mutually exclusive.
Specifies how many requests can be outstanding at any one time. Increasing this can slightly improve file transfer speed but increases memory usage. The default is 16 outstanding requests.
-s subsystem | sftp_server
Specifies the SSH2 subsystem or the path for an sftp server on the remote host. A path is useful for using sftp over protocol version 1, or when the remote sshd does not have an sftp subsystem configured.
-S ssh_program path
Uses the specified program instead of ssh(1) to connect to the sftp server. The -P and -S options are mutually exclusive.
Raises logging level. This option is also passed to ssh(1).
Specifies the use of protocol version 1.
The following operands are supported:
hostname | [email protected]
The name of the host to which sftp connects and logs into.
Once in interactive mode, sftp understands a set of commands similar to those of ftp(1). Commands are case insensitive and path names can be enclosed in quotes if they contain spaces.
Changes remote directory to path.
chgrp grp path
Changes group of file path to grp. grp must be a numeric GID.
chmod mode path
Changes permissions of file path to mode.
chown own path
Changes owner of file path to own. own must be a numeric UID.
get [flags] remote-path [local-path]
Retrieves the remote-path and stores it on the local machine. If the local path name is not specified, it is specified the same name it has on the remote machine. If the -P flag is specified, then the file's full permission and access time are copied too.
Displays help text.
Identical to the ? command.
Changes local directory to path.
lls [ls-options [path]]
Displays local directory listing of either path or current directory if path is not specified.
Creates local directory specified by path.
ln oldpath newpath
Creates a link from oldpath to newpath.
Prints local working directory.
ls [flags] [path]
Displays remote directory listing of either path or current directory if path is not specified.
Sets local umask to umask.
Creates remote directory specified by path.
put [flags] local-path [local-path]
Uploads local-path and stores it on the remote machine. If the remote path name is not specified, it is specified the same name it has on the local machine. If the -P flag is specified, then the file's full permission and access time are copied too.
Displays remote working directory.
rename oldpath newpath
Renames remote file from oldpath to newpath.
Deletes remote file specified by path.
Removes remote directory specified by path.
symlink oldpath newpath
Creates a symbolic link from oldpath to newpath.
Displays the sftp protocol version.
Include a comment. This is useful in batch files.
If command is not specified, escapes to the local shell.
If command is specified, executes command in the local shell.
Displays help text.
Identical to the help command.
The following exit values are returned:
An error occurred.
