sftp(1) User Commands sftp(1) NAME
sftp - secure file transfer program SYNOPSIS
sftp [options] [user@]host[:dir[/]] sftp [options] [user@]host[:file1 [file1 [file | dir2]] DESCRIPTION
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 given host and enter an interactive mode. If a username was provided then sftp tries to log in as the given user. If a directory is provided then sftp tries to change the current directory on the server to the given direc- tory before entering the interactive mode. The second usage format retrieves the given file from the server and copies it to the given target file or directory on the client. If a username is given sftp tries to log in as the given user. OPTIONS
The following options are supported: -1 Specifies the use of protocol version 1. -b batchfile 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. -B buffer_size 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. -C Enables compression, using the -C flag in ssh(1). -F ssh_config Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1). -o ssh_option Specifies an option to be directly passed to ssh(1). -P sftp_server path Executes the given 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. -R num_requests 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 ssh program path Uses the given program instead of ssh(1) to connect to the sftp server. The -P and -S options are mutually exclusive. -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. -v Raises logging level. This option is also passed to ssh(1). OPERANDS
The following operands are supported: hostname | user@hostname The name of the host to which sftp connects and logs into. INTERACTIVE COMMANDS
Once in interactive mode, sftp understands a set of commands similar to those of ftp(1). Commands are case insensitive and pathnames can be enclosed in quotes if they contain spaces. bye Quits sftp. cd path Changes remote directory to path. lcd path Changes local 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. help Displays help text. 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 given 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. lls [ls-options [path]] Displays local directory listing of either path or current directory if path is not specified. lmkdir path Creates local directory specified by path. ln oldpath newpath Creates a link from oldpath to newpath. lpwd Prints local working directory. ls [flags] [path] Displays remote directory listing of either path or current directory if path is not specified. lumask umask Sets local umask to umask. mkdir path 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 given 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. pwd Displays remote working directory. exit Quits sftp. quit Quits sftp. rename oldpath newpath Renames remote file from oldpath to newpath. rmdir path Removes remote directory specified by path. rm path Deletes remote file specified by path. symlink oldpath newpath Creates a symbolic link from oldpath to newpath. ! command Executes command in local shell. ! Escapes to local shell. ? Synonym for help. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error occurred. ATTRIBUTES
