netrc(5) File Formats Manual netrc(5) Name netrc - file used by ftp auto-login procedure (.netrc) Description The file contains frequently needed options for transfers. The file resides in the owner's home directory on the machine from which the owner initiates the file transfer. If the file includes passwords, set permissions on the file with so that only the owner has read per- mission. The file uses the following format: o Each line of the file defines options for a specific machine. o A line in the file can be either a machine line or a default line. o The default line must be the first line in the file if it is present. o Fields in a default line appear in this order: default, default machine name. o Fields in a machine line appear in this order: machine, machine name, options. o Fields on each line are separated by spaces or tabs. The following are valid options for a machine line: ------------------------------------------------------------------- Option Parameter Default Description ------------------------------------------------------------------- machine machine name none Identifies a remote machine name login name local name Identifies user on the remote machine password password none Password for remote login name account password none Additional account password macdef macro name none Defines a macro like the ftp macdef command ------------------------------------------------------------------- Example This is an example of a file: machine cactus login smith machine nic.ddn.mil login anonymous password anonymous machine palm.stateu.edu login smith password ualonerwelcome macdef byenow quit macdef ls dir The first line allows to log Smith into the machine after prompting for and receiving Smith's password, as shown in this example: $ ftp cactus Connected to cactus.tech.edu FTP server ready. Password required for SMITH. User logged in ftp> The second line of the file allows the user to perform an anonymous transfer after typing this command: $ ftp nic.ddn.mil See for a description of anonymous FTP transfers. The third line allows Smith to log into the machine Smith will not be prompted for a password because this machine line includes password information. Because the file includes password information, the file must not have read permission set for world and group. The lines are macro definitions, which operate much like shell aliases. A blank line must follow each macro definition to signal the end of the macro. The first macro definition defines as an alias for the command. See Also ftp(1c) netrc(5)
