61e96248 | 56 | .Sh DESCRIPTION |
57 | .Nm | |
58 | is an interactive file transfer program, similar to | |
59 | .Xr ftp 1 , | |
60 | which performs all operations over an encrypted | |
61 | .Xr ssh 1 | |
62 | transport. | |
63 | It may also use many features of ssh, such as public key authentication and | |
64 | compression. | |
65 | .Nm | |
66 | connects and logs into the specified | |
cf7ff074 | 67 | .Ar host , |
61e96248 | 68 | then enters an interactive command mode. |
69 | .Pp | |
3730bb22 | 70 | The second usage format will retrieve files automatically if a non-interactive |
cf7ff074 | 71 | authentication method is used; otherwise it will do so after |
72 | successful interactive authentication. | |
edeeab1e | 73 | .Pp |
81466908 | 74 | The third usage format allows the sftp client to start in a remote directory. |
edeeab1e | 75 | .Pp |
bd47824b | 76 | The final usage format allows for automated sessions using the |
81466908 | 77 | .Fl b |
bd47824b | 78 | option. |
79 | In such cases, it is usually necessary to configure public key authentication | |
80 | to obviate the need to enter a password at connection time (see | |
81466908 | 81 | .Xr sshd 8 |
72c5fe79 | 82 | and |
81466908 | 83 | .Xr ssh-keygen 1 |
bd47824b | 84 | for details). |
61e96248 | 85 | The options are as follows: |
86 | .Bl -tag -width Ds | |
433e60ac | 87 | .It Fl 1 |
88 | Specify the use of protocol version 1. | |
89 | .It Fl B Ar buffer_size | |
90 | Specify the size of the buffer that | |
91 | .Nm | |
92 | uses when transferring files. | |
93 | Larger buffers require fewer round trips at the cost of higher | |
94 | memory consumption. | |
95 | The default is 32768 bytes. | |
a5ec8a3d | 96 | .It Fl b Ar batchfile |
97 | Batch mode reads a series of commands from an input | |
acf06a60 | 98 | .Ar batchfile |
a5ec8a3d | 99 | instead of |
acf06a60 | 100 | .Em stdin . |
101 | Since it lacks user interaction it should be used in conjunction with | |
f74de0d7 | 102 | non-interactive authentication. |
a8b64bb8 | 103 | A |
f74de0d7 | 104 | .Ar batchfile |
105 | of | |
106 | .Sq \- | |
a8b64bb8 | 107 | may be used to indicate standard input. |
acf06a60 | 108 | .Nm |
3730bb22 | 109 | will abort if any of the following |
110 | commands fail: | |
7e35f994 | 111 | .Ic get , put , rename , ln , |
a4e5acef | 112 | .Ic rm , mkdir , chdir , ls , |
9a36208d | 113 | .Ic lchdir , chmod , chown , chgrp , lpwd |
a5ec8a3d | 114 | and |
acf06a60 | 115 | .Ic lmkdir . |
a4e5acef | 116 | Termination on error can be suppressed on a command by command basis by |
117 | prefixing the command with a | |
f74de0d7 | 118 | .Sq \- |
bd47824b | 119 | character (for example, |
120 | .Ic -rm /tmp/blah* ) . | |
433e60ac | 121 | .It Fl C |
122 | Enables compression (via ssh's | |
123 | .Fl C | |
124 | flag). | |
125 | .It Fl F Ar ssh_config | |
126 | Specifies an alternative | |
127 | per-user configuration file for | |
128 | .Xr ssh 1 . | |
129 | This option is directly passed to | |
130 | .Xr ssh 1 . | |
61e96248 | 131 | .It Fl o Ar ssh_option |
38539909 | 132 | Can be used to pass options to |
133 | .Nm ssh | |
c21a7c4a | 134 | in the format used in |
135 | .Xr ssh_config 5 . | |
136 | This is useful for specifying options | |
38539909 | 137 | for which there is no separate |
138 | .Nm sftp | |
bd47824b | 139 | command-line flag. |
140 | For example, to specify an alternate port use: | |
e3c1c3e6 | 141 | .Ic sftp -oPort=24 . |
433e60ac | 142 | For full details of the options listed below, and their possible values, see |

7d5e8c46 | 195 | (rather than via |
281cf948 | 196 | .Xr ssh 1 ) . |
7d5e8c46 | 197 | This option may be useful in debugging the client and server. |
c25d3df7 | 198 | .It Fl R Ar num_requests |
bd47824b | 199 | Specify how many requests may be outstanding at any one time. |
200 | Increasing this may slightly improve file transfer speed | |
201 | but will increase memory usage. | |
202 | The default is 16 outstanding requests. | |
e3c1c3e6 | 203 | .It Fl S Ar program |
204 | Name of the | |
205 | .Ar program | |
206 | to use for the encrypted connection. | |

208 | .Xr ssh 1 | |
209 | options. | |
433e60ac | 210 | .It Fl s Ar subsystem | sftp_server |
211 | Specifies the SSH2 subsystem or the path for an sftp server | |
212 | on the remote host. | |
213 | A path is useful for using | |
214 | .Nm | |
215 | over protocol version 1, or when the remote | |
216 | .Xr sshd 8 | |
217 | does not have an sftp subsystem configured. | |
218 | .It Fl v | |
219 | Raise logging level. | |
220 | This option is also passed to ssh. | |
