.IP
The
.BR "-W" ", " "-X" ", and " "-Y"
options are useful for advanced users who need to tweak
behavior on some servers.
For example, users accessing mainframes might need to send
some special SITE commands to set blocksize and record format information.
.IP
For these options, you can use them multiple times each if you need
to send multiple commands.
For the
.B "-X"
option, you can use the cookie
.B %s
to expand into the name of the file that was transferred.

.SH "DESCRIPTION"
.\"-------
.PP
The
purpose of
.I ncftpls
is to do remote directory listings using
the File Transfer Protocol without entering an interactive shell.
This lets you write shell scripts or other unattended
processes that can do FTP.
.PP
The default behavior is to print the directory listing in columnized
format (i.e. ls\ \-CF), but that is not very useful for scripting.
This example uses the
.B \-1
flag, to print one file per line:
.RS 4
.br
.sp
$ ncftpls -1 ftp://ftp.ncftp.com/pub/ncftp/
.RE
.PP
You can also do a remote "ls\ \-l", by using "ncftpls\ \-l".
If you want to try other flags, you have to use them with the
.B \-x
flag.
For example, if you wanted to do a remote "ls\ \-lrt", you could
do this:
.RS 4
.br
.sp
$ ncftpls -x "-lrt" ftp://ftp.ncftp.com/pub/ncftp/
.RE
.PP
By default the program tries to open the remote host
and login anonymously, but you can specify a username
and password information like you can with
.I ncftpget
or
.IR ncftpput "."
