FTP Options
===========

`-nr'
`--dont-remove-listing'
     Don't remove the temporary `.listing' files generated by FTP
     retrievals.  Normally, these files contain the raw directory
     listings received from FTP servers.  Not removing them can be
     useful for debugging purposes, or when you want to be able to
     easily check on the contents of remote server directories (e.g. to
     verify that a mirror you're running is complete).

     Note that even though Wget writes to a known filename for this
     file, this is not a security hole in the scenario of a user making
     `.listing' a symbolic link to `/etc/passwd' or something and
     asking `root' to run Wget in his or her directory.  Depending on
     the options used, either Wget will refuse to write to `.listing',
     making the globbing/recursion/time-stamping operation fail, or the
     symbolic link will be deleted and replaced with the actual
     `.listing' file, or the listing will be written to a
     `.listing.NUMBER' file.

     Even though this situation isn't a problem, though, `root' should
     never run Wget in a non-trusted user's directory.  A user could do
     something as simple as linking `index.html' to `/etc/passwd' and
     asking `root' to run Wget with `-N' or `-r' so the file will be
     overwritten.

`-g on/off'
`--glob=on/off'
     Turn FTP globbing on or off.  Globbing means you may use the
     shell-like special characters ("wildcards"), like `*', `?', `['
     and `]' to retrieve more than one file from the same directory at
     once, like:

          wget ftp://gnjilux.srk.fer.hr/*.msg

     By default, globbing will be turned on if the URL contains a
     globbing character.  This option may be used to turn globbing on
     or off permanently.

     You may have to quote the URL to protect it from being expanded by
     your shell.  Globbing makes Wget look for a directory listing,
     which is system-specific.  This is why it currently works only
     with Unix FTP servers (and the ones emulating Unix `ls' output).

`--passive-ftp'
     Use the "passive" FTP retrieval scheme, in which the client
     initiates the data connection.  This is sometimes required for FTP
     to work behind firewalls.

`--retr-symlinks'
     Usually, when retrieving FTP directories recursively and a symbolic
     link is encountered, the linked-to file is not downloaded.
     Instead, a matching symbolic link is created on the local
     filesystem.  The pointed-to file will not be downloaded unless
     this recursive retrieval would have encountered it separately and
     downloaded it anyway.

     When `--retr-symlinks' is specified, however, symbolic links are
     traversed and the pointed-to files are retrieved.  At this time,
     this option does not cause Wget to traverse symlinks to
     directories and recurse through them, but in the future it should
     be enhanced to do this.

     Note that when retrieving a file (not a directory) because it was
     specified on the commandline, rather than because it was recursed
     to, this option has no effect.  Symbolic links are always
     traversed in this case.
