6 netrc - file for ftp remote login data
7
9 The .netrc file contains data for logging in to a remote host over the
10 network for file transfers by ftp(1). This file resides in the user's
11 home directory on the machine initiating the file transfer. Its permis‐
12 sions should be set to disallow read access by group and others. See
13 chmod(1).
14 Tokens can be separated by SPACE, TAB, or NEWLINE characters. The fol‐
17 lowing tokens are supported:
18 account string Supply an additional account password. If this token
20 is present, the auto-login process supplies the
21 specified string if the remote server requires an
22 additional account password. If the remote server
23 does not require an additional account password, the
24 auto-login process initiates an ACCT command.
25 default Same as machine name, except that default matches
28 any name. There can be only one default token, and
29 it must be after all machine tokens. The default
30 token is normally used as follows:
31 default login anonymous password user@site
33 Such an entry gives the user automatic anonymous ftp
36 login to machines not specified in .netrc.
37 login name Identify a user on the remote machine. If this token
40 is present, the auto-login process initiates a login
41 using the specified name.
42 machine name Identify a remote machine name. The auto-login
45 process searches the .netrc file for a machine token
46 that matches the remote machine specified on the ftp
47 command line or as an open command argument. Once a
48 match is made, the subsequent .netrc tokens are pro‐
49 cessed, stopping when the EOF is reached or another
50 machine token is encountered.
51 macdef name Define a macro. This token functions the same as ftp
54 macdef. A macro is defined with the specified name;
55 its contents begin with the next .netrc line and
56 continue until a null line (consecutive NEWLINE
57 characters) is encountered. If a macro named init is
58 defined, it is automatically executed as the last
59 step in the auto-login process.
60 password string Supply a password. If this token is present, the
63 auto-login process supplies the specified string if
64 the remote server requires a password as part of the
65 login process. If this token is present in the
66 .netrc file, ftp aborts the auto-login process if
67 the .netrc is readable by anyone besides the user.
68 skipsyst Skip the SYST command that is sent by default to all
71 remote servers upon connection. The system command
72 is what enables the automatic use of binary mode
73 rather than the protocol default ascii mode.
74 As some older servers cannot handle the ftp command,
76 this directive is provided to allow inter-operabil‐
77 ity with these servers.

85 machine ray login demo password mypassword
88 allows an autologin to the machine ray using the login name demo with
92 password mypassword.
