Erreur lftp

     mirror [OPTS] [source [target]]

     Mirror specified source directory to local target directory.
     If  target directory ends with a slash, the source base name
     is appended to target directory name. Source  and/or  target
     can be URLs pointing to directories.

              --loop          loop until no changes found
          -i RX, --include RX include matching files
          -x RX, --exclude RX exclude matching files
          -I GP, --include-glob GP include matching files
          -X GP, --exclude-glob GP exclude matching files
          -v, --verbose[=level]    verbose operation
              --log=FILE      write lftp commands being executed to FILE
              --script=FILE        write lftp commands to FILE, but don't execute them
              --just-print, --dry-run   same as --script=-

     When  using  -R, the first directory is local and the second
     is remote.  If the second directory is omitted, base name of
     first  directory  is used.  If both directories are omitted,
     current local and remote directories are  used.   If  target
     directory  ends  with  a  slash (except root directory) then
     base name of source directory is appended.

     RX is an extended regular expression, just like in egrep(1).

     GP is a glob pattern, e.g. '*.zip'.

     Include and exclude options can be specified multiple times.
     It means that a file or directory would be  mirrored  if  it
     matches  an include and does not match to excludes after the
     include, or does not match anything and the first  check  is
     exclude. Directories are matched with a slash appended.

     Note  that  symbolic links are not created when uploading to
     remote server, because ftp protocol cannot do it. To  upload
     files  the  links  refer to, use 'mirror -RL' command (treat
     symbolic links as files).

     For option --newer-than you can either  specify  a  file  or
     time  specification  like  that  used by at(1) command, e.g.
     'now-7days' or 'week ago'. If you specify a file, then modi-
     fication time of that file will be used.

     Verbosity level can be selected using --verbose=level option
     or by several -v options, e.g. -vvv. Levels are:
          0 - no output (default)
          1 - print actions
          2 - +print not deleted file names (when -e is not specified)
          3 - +print directory names which are mirrored
