NAME
       getls-lR - get ls-lR files from FTP server for mirror use

SYNOPSIS
       getls-lR [--help] [--version] SITE RPATH LPATH


DESCRIPTION
       getls-lR, getls-lR.exp and getls-lR.pl are three example scripts each of which perform the
       same function but using different libraries or languages. They are examples of how to  use
       the  ls-lR  files  generated  on remote FTP servers by mkls-lR to keep a local copy of the
       remote directory listing up to date with minimal download volume.  Your FTP mirror program
       or  script  must be able to use such a local copy or be modified to use it before getls-lR
       is useful.

       These scripts log into FTP server SITE anonymously or from a ~/.netrc  file,  request  the
       file  RPATH.times and then from this and file LPATH decide whether to: do nothing as LPATH
       is up to date; get RPATH.patch.gz and patch LPATH; or FTP RPATH.gz and replace LPATH.

       Please see README.ls-lR for details of patches to allow version 2.9  of  Lee  McLoughlin's
       perl  script  mirror  to  use  these ls-lR files.  getls-lR and workalikes are for systems
       which do not have Lee's mirror 2.9 or cannot use it and as an example of how to  modify  a
       mirror program to use mkls-lR's output like mirror 2.9 can.

       getls-lR  is  a perl script which uses Lee McLoughlin's ftp.pl and lchat.pl from directory
       /usr/lib/mirror Linux hostname and GNU gunzip and patch.

       getls-lR.exp is an expect script which uses an ftp  client  program  and  GNU  gunzip  and
       patch.  It is the fastest and uses the least memory of the three scripts.

       getls-lR.pl  is  a  perl  script which uses Net::FTP and Net::Netrc from the standard perl
       library and GNU gunzip and patch.


EXAMPLE
       getls-lR would normally be started by cron several times a day to ensure the local copy of
       the remote ls-lR is up to date when the local mirror program wishes to use it.


       getls-lR ctan.unsw.edu.au /pub/ls-lR /home/ftp/pub/remote_ls-lR
              Download  ls-lR.times  from  ctan.unsw.edu.au directory /pub and then do nothing or
              download either ls-lR.patch.gz  and  patch  or  ls-lR.gz  and  replace  local  file
              remote_ls-lR in local directory /home/ftp/pub.



OPTIONS
       --help Display help message then exit.

       and ls-lR.times.
