\bt, each remote file name is
154 expanded separately on the remote machine and the lists are
155 not merged. Expansion of a directory name is likely to be
156 different from expansion of the name of an ordinary file: the
157 exact result depends on the foreign operating system and ftp
158 server, and can be previewed by doing `mls remote-files -'.
159 As a security measure, remotely globbed files that starts
160 with `/' or contains `../', will not be automatically re-
161 ceived. If you have interactive prompting turned off, these
162 filenames will be ignored. Note: m

206 `i' signals that macro processor that the executing macro is
207 to be looped. On the first pass `$i' is replaced by the

337 connection and return the address of that port. The remote
338 server listens on that port and the client connects to it.
339 When using the more traditional PORT command, the client lis-
340 tens on a port and sends that address to the remote server,

518 To abort a file transfer, use the terminal interrupt key (usually Ctrl-
519 C). Sending transfers will be immediately halted. Receiving transfers
520 will be halted by sending a ftp protocol ABOR command to the remote serv-
521 er, and discarding any further data received. The speed at which this is
522 accomplished depends upon the remote server's support for ABOR process-
523 ing. If the remote server does not support the ABOR command, an `ftp>'
524 prompt will not appear until the remote server has completed sending the
528 The terminal interrupt key sequence will be ignored when f
\bft
\btp
\bp has complet-
529 ed any local processing and is awaiting a reply from the remote server.
530 A long delay in this mode may result from the ABOR processing described
531 above, or from unexpected behavior by the remote server, including viola-
532 tions of the ftp protocol. If the delay results from unexpected remote
533 server behavior, the local f
\bft
\btp
\bp program must be killed by hand.

536 Files specified as arguments to f

\btp
\bp commands are processed according to
539 1. If the file name `-
\b-' is specified, the _

\bt_
\bd_
\bi_
\bn (for reading) or _
\bs_
\bt_
\bd_
\bo_

\bt
540 (for writing) is used.
542 2. If the first character of the file name is `|', the remainder of the
543 argument is interpreted as a shell command. F
\bFt
\btp
\bp then forks a shell,
544 using popen(3) with the argument supplied, and reads (writes) from
545 the stdout (stdin). If the shell command includes spaces, the argu-
546 ment must be quoted; e.g. ``" ls -lt"''. A particularly useful ex-
547 ample of this mechanism is: ``dir more''.
549 3. Failing the above checks, if ``globbing'' is enabled, local file
550 names are expanded according to the rules used in the csh(1); c.f.
551 the g
