1SFTP(1) General Commands Manual SFTP(1) 2 3NAME 4 sftp M-bM-^@M-^S secure file transfer program 5 6SYNOPSIS 7 sftp [-1246aCfpqrv] [-B buffer_size] [-b batchfile] [-c cipher] 8 [-D sftp_server_path] [-F ssh_config] [-i identity_file] [-l limit] 9 [-o ssh_option] [-P port] [-R num_requests] [-S program] 10 [-s subsystem | sftp_server] host 11 sftp [user@]host[:file ...] 12 sftp [user@]host[:dir[/]] 13 sftp -b batchfile [user@]host 14 15DESCRIPTION 16 sftp is an interactive file transfer program, similar to ftp(1), which 17 performs all operations over an encrypted ssh(1) transport. It may also 18 use many features of ssh, such as public key authentication and 19 compression. sftp connects and logs into the specified host, then enters 20 an interactive command mode. 21 22 The second usage format will retrieve files automatically if a non- 23 interactive authentication method is used; otherwise it will do so after 24 successful interactive authentication. 25 26 The third usage format allows sftp to start in a remote directory. 27 28 The final usage format allows for automated sessions using the -b option. 29 In such cases, it is necessary to configure non-interactive 30 authentication to obviate the need to enter a password at connection time 31 (see sshd(8) and ssh-keygen(1) for details). 32 33 Since some usage formats use colon characters to delimit host names from 34 path names, IPv6 addresses must be enclosed in square brackets to avoid 35 ambiguity. 36 37 The options are as follows: 38 39 -1 Specify the use of protocol version 1. 40 41 -2 Specify the use of protocol version 2. 42 43 -4 Forces sftp to use IPv4 addresses only. 44 45 -6 Forces sftp to use IPv6 addresses only. 46 47 -a Attempt to continue interrupted transfers rather than overwriting 48 existing partial or complete copies of files. If the partial 49 contents differ from those being transferred, then the resultant 50 file is likely to be corrupt. 51 52 -B buffer_size 53 Specify the size of the buffer that sftp uses when transferring 54 files. Larger buffers require fewer round trips at the cost of 55 higher memory consumption. The default is 32768 bytes. 56 57 -b batchfile 58 Batch mode reads a series of commands from an input batchfile 59 instead of stdin. Since it lacks user interaction it should be 60 used in conjunction with non-interactive authentication. A 61 batchfile of M-bM-^@M-^X-M-bM-^@M-^Y may be used to indicate standard input. sftp 62 will abort if any of the following commands fail: get, put, 63 reget, reput, rename, ln, rm, mkdir, chdir, ls, lchdir, chmod, 64 chown, chgrp, lpwd, df, symlink, and lmkdir. Termination on 65 error can be suppressed on a command by command basis by 66 prefixing the command with a M-bM-^@M-^X-M-bM-^@M-^Y character (for example, -rm 67 /tmp/blah*). 68 69 -C Enables compression (via ssh's -C flag). 70 71 -c cipher 72 Selects the cipher to use for encrypting the data transfers. 73 This option is directly passed to ssh(1). 74 75 -D sftp_server_path 76 Connect directly to a local sftp server (rather than via ssh(1)). 77 This option may be useful in debugging the client and server. 78 79 -F ssh_config 80 Specifies an alternative per-user configuration file for ssh(1). 81 This option is directly passed to ssh(1). 82 83 -f Requests that files be flushed to disk immediately after 84 transfer. When uploading files, this feature is only enabled if 85 the server implements the "fsync@openssh.com" extension. 86 87 -i identity_file 88 Selects the file from which the identity (private key) for public 89 key authentication is read. This option is directly passed to 90 ssh(1). 91 92 -l limit 93 Limits the used bandwidth, specified in Kbit/s. 94 95 -o ssh_option 96 Can be used to pass options to ssh in the format used in 97 ssh_config(5). This is useful for specifying options for which 98 there is no separate sftp command-line flag. For example, to 99 specify an alternate port use: sftp -oPort=24. For full details 100 of the options listed below, and their possible values, see 101 ssh_config(5). 102 103 AddressFamily 104 BatchMode 105 BindAddress 106 CanonicalDomains 107 CanonicalizeFallbackLocal 108 CanonicalizeHostname 109 CanonicalizeMaxDots 110 CanonicalizePermittedCNAMEs 111 ChallengeResponseAuthentication 112 CheckHostIP 113 Cipher 114 Ciphers 115 Compression 116 CompressionLevel 117 ConnectionAttempts 118 ConnectTimeout 119 ControlMaster 120 ControlPath 121 ControlPersist 122 GlobalKnownHostsFile 123 GSSAPIAuthentication 124 GSSAPIDelegateCredentials 125 HashKnownHosts 126 Host 127 HostbasedAuthentication 128 HostbasedKeyTypes 129 HostKeyAlgorithms 130 HostKeyAlias 131 HostName 132 IdentityFile 133 IdentitiesOnly 134 IPQoS 135 KbdInteractiveAuthentication 136 KbdInteractiveDevices 137 KexAlgorithms 138 LogLevel 139 MACs 140 NoHostAuthenticationForLocalhost 141 NumberOfPasswordPrompts 142 PasswordAuthentication 143 PKCS11Provider 144 Port 145 PreferredAuthentications 146 Protocol 147 ProxyCommand 148 PubkeyAuthentication 149 RekeyLimit 150 RhostsRSAAuthentication 151 RSAAuthentication 152 SendEnv 153 ServerAliveInterval 154 ServerAliveCountMax 155 StrictHostKeyChecking 156 TCPKeepAlive 157 UpdateHostKeys 158 UsePrivilegedPort 159 User 160 UserKnownHostsFile 161 VerifyHostKeyDNS 162 163 -P port 164 Specifies the port to connect to on the remote host. 165 166 -p Preserves modification times, access times, and modes from the 167 original files transferred. 168 169 -q Quiet mode: disables the progress meter as well as warning and 170 diagnostic messages from ssh(1). 171 172 -R num_requests 173 Specify how many requests may be outstanding at any one time. 174 Increasing this may slightly improve file transfer speed but will 175 increase memory usage. The default is 64 outstanding requests. 176 177 -r Recursively copy entire directories when uploading and 178 downloading. Note that sftp does not follow symbolic links 179 encountered in the tree traversal. 180 181 -S program 182 Name of the program to use for the encrypted connection. The 183 program must understand ssh(1) options. 184 185 -s subsystem | sftp_server 186 Specifies the SSH2 subsystem or the path for an sftp server on 187 the remote host. A path is useful for using sftp over protocol 188 version 1, or when the remote sshd(8) does not have an sftp 189 subsystem configured. 190 191 -v Raise logging level. This option is also passed to ssh. 192 193INTERACTIVE COMMANDS 194 Once in interactive mode, sftp understands a set of commands similar to 195 those of ftp(1). Commands are case insensitive. Pathnames that contain 196 spaces must be enclosed in quotes. Any special characters contained 197 within pathnames that are recognized by glob(3) must be escaped with 198 backslashes (M-bM-^@M-^X\M-bM-^@M-^Y). 199 200 bye Quit sftp. 201 202 cd path 203 Change remote directory to path. 204 205 chgrp grp path 206 Change group of file path to grp. path may contain glob(3) 207 characters and may match multiple files. grp must be a numeric 208 GID. 209 210 chmod mode path 211 Change permissions of file path to mode. path may contain 212 glob(3) characters and may match multiple files. 213 214 chown own path 215 Change owner of file path to own. path may contain glob(3) 216 characters and may match multiple files. own must be a numeric 217 UID. 218 219 df [-hi] [path] 220 Display usage information for the filesystem holding the current 221 directory (or path if specified). If the -h flag is specified, 222 the capacity information will be displayed using "human-readable" 223 suffixes. The -i flag requests display of inode information in 224 addition to capacity information. This command is only supported 225 on servers that implement the M-bM-^@M-^\statvfs@openssh.comM-bM-^@M-^] extension. 226 227 exit Quit sftp. 228 229 get [-afPpr] remote-path [local-path] 230 Retrieve the remote-path and store it on the local machine. If 231 the local path name is not specified, it is given the same name 232 it has on the remote machine. remote-path may contain glob(3) 233 characters and may match multiple files. If it does and 234 local-path is specified, then local-path must specify a 235 directory. 236 237 If the -a flag is specified, then attempt to resume partial 238 transfers of existing files. Note that resumption assumes that 239 any partial copy of the local file matches the remote copy. If 240 the remote file contents differ from the partial local copy then 241 the resultant file is likely to be corrupt. 242 243 If the -f flag is specified, then fsync(2) will be called after 244 the file transfer has completed to flush the file to disk. 245 246 If either the -P or -p flag is specified, then full file 247 permissions and access times are copied too. 248 249 If the -r flag is specified then directories will be copied 250 recursively. Note that sftp does not follow symbolic links when 251 performing recursive transfers. 252 253 help Display help text. 254 255 lcd path 256 Change local directory to path. 257 258 lls [ls-options [path]] 259 Display local directory listing of either path or current 260 directory if path is not specified. ls-options may contain any 261 flags supported by the local system's ls(1) command. path may 262 contain glob(3) characters and may match multiple files. 263 264 lmkdir path 265 Create local directory specified by path. 266 267 ln [-s] oldpath newpath 268 Create a link from oldpath to newpath. If the -s flag is 269 specified the created link is a symbolic link, otherwise it is a 270 hard link. 271 272 lpwd Print local working directory. 273 274 ls [-1afhlnrSt] [path] 275 Display a remote directory listing of either path or the current 276 directory if path is not specified. path may contain glob(3) 277 characters and may match multiple files. 278 279 The following flags are recognized and alter the behaviour of ls 280 accordingly: 281 282 -1 Produce single columnar output. 283 284 -a List files beginning with a dot (M-bM-^@M-^X.M-bM-^@M-^Y). 285 286 -f Do not sort the listing. The default sort order is 287 lexicographical. 288 289 -h When used with a long format option, use unit suffixes: 290 Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte, 291 and Exabyte in order to reduce the number of digits to 292 four or fewer using powers of 2 for sizes (K=1024, 293 M=1048576, etc.). 294 295 -l Display additional details including permissions and 296 ownership information. 297 298 -n Produce a long listing with user and group information 299 presented numerically. 300 301 -r Reverse the sort order of the listing. 302 303 -S Sort the listing by file size. 304 305 -t Sort the listing by last modification time. 306 307 lumask umask 308 Set local umask to umask. 309 310 mkdir path 311 Create remote directory specified by path. 312 313 progress 314 Toggle display of progress meter. 315 316 put [-afPpr] local-path [remote-path] 317 Upload local-path and store it on the remote machine. If the 318 remote path name is not specified, it is given the same name it 319 has on the local machine. local-path may contain glob(3) 320 characters and may match multiple files. If it does and 321 remote-path is specified, then remote-path must specify a 322 directory. 323 324 If the -a flag is specified, then attempt to resume partial 325 transfers of existing files. Note that resumption assumes that 326 any partial copy of the remote file matches the local copy. If 327 the local file contents differ from the remote local copy then 328 the resultant file is likely to be corrupt. 329 330 If the -f flag is specified, then a request will be sent to the 331 server to call fsync(2) after the file has been transferred. 332 Note that this is only supported by servers that implement the 333 "fsync@openssh.com" extension. 334 335 If either the -P or -p flag is specified, then full file 336 permissions and access times are copied too. 337 338 If the -r flag is specified then directories will be copied 339 recursively. Note that sftp does not follow symbolic links when 340 performing recursive transfers. 341 342 pwd Display remote working directory. 343 344 quit Quit sftp. 345 346 reget [-Ppr] remote-path [local-path] 347 Resume download of remote-path. Equivalent to get with the -a 348 flag set. 349 350 reput [-Ppr] [local-path] remote-path 351 Resume upload of [local-path]. Equivalent to put with the -a 352 flag set. 353 354 rename oldpath newpath 355 Rename remote file from oldpath to newpath. 356 357 rm path 358 Delete remote file specified by path. 359 360 rmdir path 361 Remove remote directory specified by path. 362 363 symlink oldpath newpath 364 Create a symbolic link from oldpath to newpath. 365 366 version 367 Display the sftp protocol version. 368 369 !command 370 Execute command in local shell. 371 372 ! Escape to local shell. 373 374 ? Synonym for help. 375 376SEE ALSO 377 ftp(1), ls(1), scp(1), ssh(1), ssh-add(1), ssh-keygen(1), glob(3), 378 ssh_config(5), sftp-server(8), sshd(8) 379 380 T.
