SYNOPSISgetls-lR [--help] [--version] SITE RPATH LPATH
DESCRIPTIONgetls-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.
EXAMPLEgetls-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.
