1.1 deraadt 88: .Sh DESCRIPTION
1.27 aaron 89: .Nm
1.86 lteo 90: is the user interface to the Internet standard File Transfer
91: Protocol (FTP).
1.1 deraadt 92: The program allows a user to transfer files to and from a
93: remote network site.
1.3 deraadt 94: .Pp
1.115 florian 95: The latter four usage formats will fetch a file using either the
96: FTP, HTTP, or HTTPS protocols into the current directory.
1.29 aaron 97: This is ideal for scripts.
98: Refer to
1.9 millert 99: .Sx AUTO-FETCHING FILES
100: below for more information.
1.7 millert 101: .Pp
1.28 aaron 102: The options are as follows:
1.32 aaron 103: .Bl -tag -width Ds
1.42 jmc 104: .It Fl 4
105: Forces
106: .Nm
107: to use IPv4 addresses only.
108: .It Fl 6
109: Forces
110: .Nm
1.115 florian 111: to use IPv6 addresses only.
1.16 millert 112: .It Fl A
1.48 jmc 113: Force active mode FTP.
1.29 aaron 114: By default,
1.16 millert 115: .Nm
1.48 jmc 116: will try to use passive mode FTP and fall back to active mode
1.29 aaron 117: if passive is not supported by the server.
118: This option causes
1.16 millert 119: .Nm
1.29 aaron 120: to always use an active connection.
121: It is only useful for connecting
1.16 millert 122: to very old servers that do not implement passive mode properly.
1.115 florian 123: .It Fl a
124: Causes
125: .Nm
126: to bypass the normal login procedure and use an anonymous login instead.
1.63 martynas 127: .It Fl C
1.65 jmc 128: Continue a previously interrupted file transfer.
1.64 jmc 129: .Nm
1.115 florian 130: will continue transferring from an offset equal to the length of
131: .Ar file .
1.65 jmc 132: .Pp
1.115 florian 133: Resuming HTTP(S) transfers are only supported
134: if the remote server supports the
1.64 jmc 135: .Dq Range
136: header.
1.115 florian 137: .It Fl c Ar cookie
138: Load a Netscape-like cookiejar file
139: for HTTP and HTTPS transfers.
140: With this option relevant cookies from the jar are sent with each HTTP(S)
141: request.
142: Setting the
143: .Ev http_cookies
144: environment variable has the same effect.
145: If both the
146: .Ev http_cookies
147: environment variable is set and the
148: .Fl c
149: argument is given, the latter takes precedence.
1.91 jmc 150: .It Fl D Ar title
1.115 florian 151: Specify a short
152: .Ar title
153: for the start of the progress bar.
154: .It Fl d
155: Enables debugging.
156: .It Fl E
157: Disables EPSV/EPRT command on IPv4 connections.
158: .It Fl e
159: Disables command line editing.
160: Useful for Emacs ange-ftp.
161: .It Fl g
162: Disables file name globbing.
163: .It Fl i
164: Turns off interactive prompting during
165: multiple file transfers.
166: .It Fl k Ar seconds
167: When greater than zero,
168: sends a byte after each
169: .Ar seconds
170: period over the control connection during long transfers,
171: so that incorrectly configured network equipment won't
172: aggressively drop it.
173: The FTP protocol supports a
174: .Dv NOOP
175: command that can be used for that purpose.
176: This assumes the FTP server can deal with extra commands coming over
177: the control connection during a transfer.
178: Well-behaved servers queue those commands, and process them after the
179: transfer.
180: By default,
181: .Nm
182: will send a byte every 60 seconds.
1.97 tedu 183: .It Fl M
184: Causes
185: .Nm
1.115 florian 186: to never display the progress meter in cases where it would do
187: so by default.
1.114 kmos 188: .It Fl m
189: Causes
190: .Nm
1.115 florian 191: to always display the progress meter in cases where it would not do
192: so by default.
1.117 jmc 193: .It Fl N Ar name
194: Use this alternative name instead of
195: .Nm
196: in some error reports.
1.115 florian 197: .It Fl n
198: Restrains
199: .Nm
200: from attempting
201: .Dq auto-login
202: upon initial connection.
203: If auto-login is enabled,
204: .Nm
205: will check the
206: .Pa .netrc
207: file (see below) in the user's home directory for an entry describing
208: an account on the remote machine.
209: If no entry exists,
210: .Nm
211: will prompt for the remote machine login name (default is the user
212: identity on the local machine) and, if necessary, prompt for a password
213: and an account with which to log in.
1.17 millert 214: .It Fl o Ar output
1.115 florian 215: When fetching a single file or URL, save the contents in
1.17 millert 216: .Ar output .
1.115 florian 217: To make the contents go to stdout,
218: use
219: .Sq -
220: for
1.17 millert 221: .Ar output .
1.115 florian 222: .It Fl P Ar port
223: Sets the port number to
224: .Ar port .
225: .It Fl p
226: Enable passive mode operation for use behind connection filtering firewalls.
227: This option has been deprecated as
228: .Nm
229: now tries to use passive mode by default, falling back to active mode
230: if the server does not support passive connections.
231: .It Fl r Ar seconds
232: Retry to connect if failed, pausing for number of
233: .Ar seconds .
234: .It Fl S Ar ssl_options
235: SSL/TLS options to use with HTTPS transfers.
1.89 jca 236: The following settings are available:
237: .Bl -tag -width Ds

1.107 jmc 263: Disable validation of certificate times and OCSP validation.
1.108 jsing 264: .It Cm session Ns = Ns Ar /path/to/session
265: Specify a file to use for TLS session data.
266: If this file has a non-zero length, the session data will be read from this file
267: and the client will attempt to resume the TLS session with the server.
1.115 florian 268: Upon completion of a successful TLS handshake this file will be updated
269: with new session data, if available.
1.108 jsing 270: This file will be created if it does not already exist.
1.89 jca 271: .El
272: .Pp

1.6 millert 320: .Nm
1.1 deraadt 321: will enter its command interpreter and await instructions
322: from the user.
323: When
1.6 millert 324: .Nm
1.42 jmc 325: is awaiting commands, the prompt
1.51 jmc 326: .Dq ftp\*(Gt
1.1 deraadt 327: is provided to the user.
328: The following commands are recognized
329: by
1.48 jmc 330: .Nm :
1.118 ! schwarze 331: .Bl -tag -width Ds
1.115 florian 332: .It Ic \&! Oo Ar command

353: .It Ic append Ar local-file Op Ar remote-file
354: Append a local file to a file on the remote machine.
355: If
356: .Ar remote-file
357: is left unspecified, the local file name is used in naming the
358: remote file after being altered by any
359: .Ic ntrans
360: or
361: .Ic nmap
362: setting.
363: File transfer uses the current settings for
364: .Ic type ,
365: .Ic format ,
366: .Ic mode ,
367: and
368: .Ic structure .
369: .It Ic ascii

414: Records are denoted by a carriage return/linefeed sequence
415: during ASCII type file transfer.
416: When
417: .Ic cr
418: is on (the default), carriage returns are stripped from this
419: sequence to conform with the
420: .Ux
421: single linefeed record delimiter.
422: Records on non-UNIX
423: remote systems may contain single linefeeds;
424: when an ASCII type transfer is made, these linefeeds may be
425: distinguished from a record delimiter only when
426: .Ic cr
427: is off.
428: .It Ic debug Oo Ic on | off |
429: .Ar debuglevel
430: .Oc
431: Toggle debugging mode.

469: .Ic open .
470: .It Ic gate Oo Ic on | off |
471: .Ar host Op Ar port
472: .Oc
473: Toggle gate-ftp mode.
474: This will not be permitted if the gate-ftp server hasn't been set
475: (either explicitly by the user, or from the
476: .Ev FTPSERVER
477: environment variable).
478: If
479: .Ar host
480: is given,
481: then gate-ftp mode will be enabled, and the gate-ftp server will be set to
482: .Ar host .
483: If
484: .Ar port
485: is also given, that will be used as the port to connect to on the
486: gate-ftp server.
487: .It Ic get Ar remote-file Op Ar local-file
488: Retrieve the
489: .Ar remote-file
490: and store it on the local machine.
491: If the local
492: file name is not specified, it is given the same
493: name it has on the remote machine, subject to
494: alteration by the current
495: .Ic case ,
496: .Ic ntrans ,
497: and
498: .Ic nmap
499: settings.
500: The current settings for
501: .Ic type ,
502: .Ic form ,

504: and
505: .Ic structure
506: are used while transferring the file.
507: .It Ic glob Op Ic on | off
508: Toggle filename expansion for
509: .Ic mdelete ,
510: .Ic mget
511: and
512: .Ic mput .
513: If globbing is turned off with
514: .Ic glob ,
515: the file name arguments
516: are taken literally and not expanded.
517: Globbing for
518: .Ic mput
519: is done as in
520: .Xr csh 1 .
521: For
522: .Ic mdelete
523: and
524: .Ic mget ,
525: each remote file name is expanded
526: separately on the remote machine and the lists are not merged.
527: Expansion of a directory name is likely to be
528: different from expansion of the name of an ordinary file:
529: the exact result depends on the foreign operating system and FTP server,
530: and can be previewed by doing
531: .Dq mls remote-files - .
532: Note:
533: .Ic mget
534: and
535: .Ic mput
536: are not meant to transfer
537: entire directory subtrees of files.
538: That can be done by
539: transferring a
540: .Xr tar 1
541: archive of the subtree (in binary mode).
542: .It Ic hash Oo Ic on | off |
543: .Ar size
544: .Oc
545: Toggle hash mark
546: .Pq Ql #

614: To invoke a macro,
615: use the
616: .Ic $
617: command (see above).
618: .Pp
619: The macro processor interprets
620: .Ql $

777: Otherwise, this command is identical to
778: .Ar get .
1.6 millert 779: .It Ic nlist Op Ar remote-directory Op Ar local-file
1.30 millert 780: Print a list of the files in a

1.38 jmc 795: the output is sent to the terminal.
796: Note that on some servers, the
1.30 millert 797: .Ic nlist
798: command will only return information on normal files (not directories
799: or special files).
1.115 florian 800: .It Ic nmap Op Ar inpattern outpattern
801: Set or unset the filename mapping mechanism.
802: If no arguments are specified, the filename mapping mechanism is unset.
803: If arguments are specified, remote filenames are mapped during
804: .Ic mput
805: commands and
806: .Ic put
807: commands issued without a specified remote target filename.
808: If arguments are specified, local filenames are mapped during
809: .Ic mget
810: commands and
811: .Ic get
812: commands issued without a specified local target filename.
813: This command is useful when connecting to a non-UNIX remote computer
814: with different file naming conventions or practices.
815: .Pp
816: The mapping follows the pattern set by
817: .Ar inpattern
818: and
819: .Ar outpattern .
820: .Ar inpattern
821: is a template for incoming filenames (which may have already been
822: processed according to the
823: .Ic ntrans
824: and
825: .Ic case
826: settings).
827: Variable templating is accomplished by including the
828: sequences
829: .Ql $1 ,
830: .Ql $2 ,
831: \&...,
832: .Ql $9
833: in
834: .Ar inpattern .
835: Use
836: .Ql \e
837: to prevent this special treatment of the
838: .Ql $
839: character.
840: All other characters are treated literally, and are used to determine the
841: .Ic nmap
842: .Ar inpattern
843: variable values.
844: .Pp
845: For example, given
846: .Ar inpattern
847: $1.$2 and the remote file name "mydata.data", $1 would have the value
848: "mydata", and $2 would have the value "data".
849: The
850: .Ar outpattern
851: determines the resulting mapped filename.
852: The sequences
853: .Ql $1 ,
854: .Ql $2 ,
855: \&...,
856: .Ql $9
857: are replaced by any value resulting from the
858: .Ar inpattern
859: template.
860: The sequence
861: .Ql $0
862: is replaced by the original filename.
863: Additionally, the sequence
864: .Sq Op Ar seq1 , Ar seq2
865: is replaced by
866: .Ar seq1
867: if
868: .Ar seq1
869: is not a null string; otherwise it is replaced by
870: .Ar seq2 .
871: For example:
872: .Pp
873: .Dl nmap $1.$2.$3 [$1,$2].[$2,file]
874: .Pp
875: This command would yield the output filename
876: .Pa myfile.data
877: for input filenames
878: .Pa myfile.data
879: and
880: .Pa myfile.data.old ;
881: .Pa myfile.file
882: for the input filename
883: .Pa myfile ;
884: and
885: .Pa myfile.myfile
886: for the input filename
887: .Pa .myfile .
888: Spaces may be included in
889: .Ar outpattern
890: by quoting them,
891: as in the following example:
892: .Bd -literal -offset indent
893: nmap $1.$2 "$1 $2"
894: .Ed
895: .Pp
896: Use the
897: .Ql \e
898: character to prevent special treatment
899: of the
900: .Ql $ ,
901: .Ql \&[ ,
902: .Ql \&] ,
903: and
904: .Ql \&,
905: characters.
906: .It Ic ntrans Op Ar inchars Op Ar outchars
907: Set or unset the filename character translation mechanism.
908: If no arguments are specified, the filename character
909: translation mechanism is unset.
910: If arguments are specified, characters in
911: remote filenames are translated during
912: .Ic mput
913: commands and
914: .Ic put
915: commands issued without a specified remote target filename.
916: If arguments are specified, characters in
917: local filenames are translated during
918: .Ic mget
919: commands and
920: .Ic get
921: commands issued without a specified local target filename.
922: This command is useful when connecting to a non-UNIX remote computer
923: with different file naming conventions or practices.
924: Characters in a filename matching a character in
925: .Ar inchars
926: are replaced with the corresponding character in
927: .Ar outchars .
928: If the character's position in
929: .Ar inchars
930: is longer than the length of
931: .Ar outchars ,
932: the character is deleted from the file name.
933: .It Ic open Ar host Op Ar port
934: Establish a connection to the specified
935: .Ar host
936: FTP server.
937: An optional port number may be supplied,
938: in which case
939: .Nm
940: will attempt to contact an FTP server at that port.
941: If the
942: .Ic auto-login
943: option is on (default),
944: .Nm
945: will also attempt to automatically log the user in to
946: the FTP server (see below).
947: .It Ic page Ar file
948: Retrieve
949: .Ic file
950: and display with the program defined in
951: .Ev PAGER
952: (defaulting to
953: .Xr more 1
954: if
955: .Ev PAGER
956: is null or not defined).
1.73 sobrado 957: .It Ic passive Op Ic on | off
1.29 aaron 958: Toggle passive mode.
1.48 jmc 959: If passive mode is turned on (default is on),
960: .Nm
961: will send a
1.57 jmc 962: .Dv EPSV
1.1 deraadt 963: command for all data connections instead of the usual
1.115 florian 964: .Dv PORT
1.29 aaron 965: command.
966: The
1.115 florian 967: .Dv PASV
1.1 deraadt 968: command requests that the remote server open a port for the data connection
1.29 aaron 969: and return the address of that port.
970: The remote server listens on that port and the client connects to it.
971: When using the more traditional
1.115 florian 972: .Dv PORT
1.1 deraadt 973: command, the client listens on a port and sends that address to the remote
1.29 aaron 974: server, who connects back to it.
975: Passive mode is useful when using
1.6 millert 976: .Nm
1.1 deraadt 977: through a gateway router or host that controls the directionality of
978: traffic.
1.115 florian 979: (Note that though FTP servers are required to support the
980: .Dv PASV
981: command by RFC 1123, some do not.)
982: .It Ic preserve Op Ic on | off
983: Toggle preservation of modification times on retrieved files.
984: .It Ic progress Op Ic on | off
985: Toggle display of transfer progress bar.
986: The progress bar will be disabled for a transfer that has
987: .Ar local-file

989: .Sq -
990: or a command that starts with
991: .Sq \&| .
992: Refer to

995: .It Ic prompt Op Ic on | off
996: Toggle interactive prompting.
997: Interactive prompting
998: occurs during multiple file transfers to allow the
999: user to selectively retrieve or store files.
1000: If prompting is turned off (default is on), any
1001: .Ic mget
1002: or
1003: .Ic mput
1004: will transfer all files, and any
1005: .Ic mdelete
1006: will delete all files.
1007: .Pp
1008: When prompting is on, the following commands are available at a prompt:

1032: to any remaining files for the current command.
1033: .It Ic y
1034: Transfer the file.
1035: .El
1036: .It Ic proxy Ar command
1037: Execute an FTP command on a secondary control connection.
1038: This command allows simultaneous connection to two remote FTP
1039: servers for transferring files between the two servers.
1040: The first
1041: .Ic proxy
1042: command should be an
1043: .Ic open ,
1044: to establish the secondary control connection.
1045: Enter the command
1046: .Ic proxy ?\&
1047: to see other FTP commands executable on the
1048: secondary connection.
1049: The following commands behave differently when prefaced by
1050: .Ic proxy :
1051: .Ic open
1052: will not define new macros during the auto-login process;
1053: .Ic close
1054: will not erase existing macro definitions;
1055: .Ic get
1056: and
1057: .Ic mget
1058: transfer files from the host on the primary control connection
1059: to the host on the secondary control connection; and
1060: .Ic put ,
1061: .Ic mput ,
1062: and
1063: .Ic append
1064: transfer files from the host on the secondary control connection
1065: to the host on the primary control connection.
1066: Third party file transfers depend upon support of the FTP protocol
1067: .Dv PASV
1068: command by the server on the secondary control connection.
1.1 deraadt 1069: .It Ic put Ar local-file Op Ar remote-file
1070: Store a local file on the remote machine.
1071: If

1.115 florian 1073: is left unspecified, the local file name is used
1074: after processing according to any
1075: .Ic ntrans
1076: or
1077: .Ic nmap
1078: settings
1079: in naming the remote file.
1080: File transfer uses the
1081: current settings for
1082: .Ic type ,

1084: .Ic mode ,
1085: and
1086: .Ic structure .

1101: exists and is
1102: smaller than
1103: .Ar remote-file ,
1104: .Ar local-file
1105: is presumed to be
1106: a partially transferred copy of
1107: .Ar remote-file
1108: and the transfer
1109: is continued from the apparent point of failure.
1110: This command
1111: is useful when transferring very large files over networks that
1112: are prone to dropping connections.
1113: .It Ic rename Ar from-name to-name
1114: Rename the file

1130: This command
1131: is useful when transferring very large files over networks that
1132: are prone to dropping connections.
1133: .It Ic reset
1134: Clear reply queue.
1135: This command re-synchronizes command/reply sequencing with the remote
1136: FTP server.
1137: Resynchronization may be necessary following a violation of the FTP protocol
1138: by the remote server.
1139: .It Ic restart Ar marker
1140: Restart the immediately following
1.1 deraadt 1141: .Ic get

1150: .Ar marker
1151: is usually a byte
1152: offset into the file.
1153: .It Ic rhelp Op Ar command-name
1154: Request help from the remote FTP server.

1449: .Sh ABORTING A FILE TRANSFER
1450: To abort a file transfer, use the terminal interrupt key
1451: (usually Ctrl-C).
1452: Sending transfers will be immediately halted.
1453: Receiving transfers will be halted by sending an FTP protocol
1454: .Dv ABOR
1455: command to the remote server, and discarding any further data received.
1456: The speed at which this is accomplished depends upon the remote
1457: server's support for

1467: The terminal interrupt key sequence will be ignored when
1468: .Nm
1469: has completed any local processing and is awaiting a reply
1470: from the remote server.
1471: A long delay in this mode may result from the ABOR processing described
1472: above, or from unexpected behavior by the remote server, including
1473: violations of the FTP protocol.
1474: If the delay results from unexpected remote server behavior, the local
1475: .Nm
1476: program must be killed by hand.
1477: .Sh FILE NAMING CONVENTIONS
1478: Files specified as arguments to

1481: .Bl -enum
1482: .It
1483: If
1484: .Sq -
1485: is specified as a local file name, the standard input (for reading)
1486: or standard output (for writing)
1487: is used.
1488: .It
1489: If the first character of a local file name is
1490: .Sq \&| ,
1491: the
1492: remainder of the argument is interpreted as a shell command.
1493: .Nm
1494: then forks a shell, using
1495: .Xr popen 3
1496: with the argument supplied, and reads (writes) from the standard output
1497: (standard input).
1498: If the shell command includes spaces, the argument
1499: must be quoted; e.g.,
1500: .Qq ls -lt .
1501: A particularly
1502: useful example of this mechanism is:
1503: .Qq ls \&. |more .
1504: .It
1505: Failing the above checks, if
1506: .Dq globbing
1507: is enabled,
1508: local file names are expanded
1509: according to the rules used in the
1510: .Xr csh 1
1511: .Ic glob
1512: command.
1513: If the
1514: .Nm
1515: command expects a single local file (e.g.,
1516: .Ic put ) ,
1517: only the first filename generated by the
1518: .Dq globbing
1519: operation is used.
1520: .It
1521: For
1522: .Ic mget
1523: commands and
1524: .Ic get
1525: commands with unspecified local file names, the local filename is

1527: .Ic case ,
1528: .Ic ntrans ,
1529: or
1530: .Ic nmap

1542: .Ic ntrans
1543: or
1544: .Ic nmap
1545: setting.
1546: The resulting filename may then be altered by the remote server if
1547: .Ic sunique
1548: is on.
1549: .El
1550: .Sh FILE TRANSFER PARAMETERS
1551: The FTP specification specifies many parameters which may
1552: affect a file transfer.
1553: The
1554: .Ic type
1555: may be one of
1556: .Dq ascii ,
1557: .Dq binary ,
1558: or
1559: .Dq image .
1560: .Nm
1561: supports the ASCII and image types of file transfer.
1562: .Pp
1563: .Nm
1564: supports only the default values for the remaining
1565: file transfer parameters:
1566: .Ic mode ,
1567: .Ic form ,
1568: and
1569: .Ic struct .
1570: .Sh THE .netrc FILE
1571: The
1572: .Pa .netrc
1573: file contains login and initialization information
1574: used by the auto-login process.
1575: It resides in the user's home directory.
1576: The following tokens are recognized; they may be separated by spaces,
1577: tabs, or new-lines:
1578: .Bl -tag -width password
1579: .It Ic machine Ar name
1580: Identify a remote machine
1581: .Ar name .
1582: The auto-login process searches the
1583: .Pa .netrc
1584: file for a
1585: .Ic machine
1586: token that matches the remote machine specified on the
1587: .Nm
1588: command line or as an
1589: .Ic open
1590: command argument.
1591: Once a match is made, the subsequent
1592: .Pa .netrc
1593: tokens are processed,
1594: stopping when the end of file is reached or another
1595: .Ic machine
1596: or a
1597: .Ic default
1598: token is encountered.
1599: .It Ic default
1600: This is the same as
1601: .Ic machine
1602: .Ar name
1603: except that
1604: .Ic default
1605: matches any name.
1606: There can be only one
1607: .Ic default
1608: token, and it must be after all
1609: .Ic machine
1610: tokens.
1611: This is normally used as:
1612: .Pp
1613: .Dl default login anonymous password user@site
1614: .Pp
1615: thereby giving the user
1616: .Ar automatic
1617: anonymous FTP login to
1618: machines not specified in
1619: .Pa .netrc .
1620: This can be overridden
1621: by using the
1622: .Fl n
1623: flag to disable auto-login.
1624: .It Ic login Ar name
1625: Identify a user on the remote machine.
1626: If this token is present, the auto-login process will initiate
1627: a login using the specified
1628: .Ar name .
1629: .It Ic password Ar string
1630: Supply a password.
1631: If this token is present, the auto-login process will supply the
1632: specified string if the remote server requires a password as part
1633: of the login process.
1634: Note that if this token is present in the
1635: .Pa .netrc
1636: file for any user other
1637: than
1638: .Ar anonymous ,
1639: .Nm
1640: will abort the auto-login process if the
1641: .Pa .netrc
1642: is readable by
1643: anyone besides the user.
1644: .It Ic account Ar string
1645: Supply an additional account password.
1646: If this token is present, the auto-login process will supply the
1647: specified string if the remote server requires an additional
1648: account password, or the auto-login process will initiate an
1649: .Dv ACCT
1650: command if it does not.
1651: .It Ic macdef Ar name
1652: Define a macro.
1653: This token functions like the
1654: .Nm
1655: .Ic macdef
1656: command functions.
1657: A macro is defined with the specified name; its contents begin with the
1658: next
1659: .Pa .netrc
1660: line and continue until a null line (consecutive new-line
1661: characters) is encountered.
1662: Like the other tokens in the
1663: .Pa .netrc
1664: file, a
1665: .Ic macdef
1666: is applicable only to the
1667: .Ic machine
1668: definition preceding it.
1669: A
1670: .Ic macdef
1671: entry cannot be utilized by multiple
1672: .Ic machine
1673: definitions; rather, it must be defined following each
1674: .Ic machine
1675: it is intended to be used with.
1676: If a macro named
1677: .Ic init
1678: is defined, it is automatically executed as the last step in the
1679: auto-login process.
1680: .El
1681: .Sh COMMAND LINE EDITING

1689: Previous lines can be recalled and edited with the arrow keys,
1690: and other GNU Emacs-style editing keys may be used as well.
1691: .Pp
1692: The
