+If arguments are specified, local filenames are mapped during

+This command is useful when connecting to a non-UNIX remote computer
+with different file naming conventions or practices.
+The mapping follows the pattern set by
+.I inpattern
+and
+.IR outpattern .
+.I Inpattern
+is a template for incoming filenames (which may have already been
+processed according to the
+.B ntrans
+and
+.B case
+settings).
+Variable templating is accomplished by including the sequences '$1', '$2', ..., '$9' in
+.IR inpattern .
+Use '\\' to prevent this special treatment of the '$' character.
+All other characters are treated literally, and are used to determine the
+.B nmap
+.I inpattern
+variable values.
+For exmaple, given
+.I inpattern
+$1.$2 and the remote file name "mydata.data", $1 would have the value
+"mydata", and $2 would have the value "data".
+The
+.I outpattern
+determines the resulting mapped filename.
+The sequences '$1', '$2', ...., '$9' are replaced by any value resulting
+from the
+.I inpattern
+template.
+The sequence '$0' is replace by the original filename.
+Additionally, the sequence '[\fIseq1\fP,\fIseq2\f\P]' is replaced by
+.I seq1
+if
+.I seq1
+is not a null string; otherwise it is replaced by
+.IR seq2 .
+For example, the command "nmap $1.$2.$3 [$1,$2].[$2,file]" would yield
+the output filename "myfile.data" for input filenames "myfile.data" and
+"myfile.data.old", "myfile.file" for the input filename "myfile", and
+"myfile.myfile" for the input filename ".myfile".
+Spaces may be included in
+.IR outpattern ,

+If this token is present, the auto-login process will supply the
+specified string if the remote server requires a password as part
+of the login process.

+.I ftp
+will abort the auto-login process if the .netrc is readable by
+anyone besides the user.
+.TP
+\fBaccount\fP \fIstring\fP
+Supply an additional account password.
+If this token is present, the auto-login process will supply the

+ACCT command if it does not.
+.TP
+\fBmacdef\fP \fIname\fP
+Define a macro.
+This token functions like the

+.B macdef
+command functions.
+A macro is defined with the specified name; its contents begin with the
+next .netrc line and continue until a null line (consecutive new-line
+characters) is encountered.
+If a macro named
+.I init
+is defined, it is automatically executed as the last step in the
+auto-login process.

+An error in the treatment of carriage returns
+in the 4.2BSD UNIX ascii-mode transfer code
+has been corrected.
+This correction may result in incorrect transfers of binary files
+to and from 4.2BSD servers using the ascii type.
+Avoid this problem by using the binary image type.
