Script to check file update on ftp server
Hi everybody,
Is there a way to do a stat of files on a ftp server? I have a database which is populated by the contents of these files. I want to setup a crontab to check if there has been an update to these files. If the file has been updated I will download it and then update my database.
I want to know of a way to compare my local files with the files on the server. I don't want to download them and then check since they are quite big.
Thanks in advance,
Dave

Update: wget -N <URL>
seems to do the job.

update-smart-drivedb updates /var/lib/smartmontools/drivedb/drivedb.h or DESTFILE from smartmontools SVN repository.
It tries to download first from the current branch and then from trunk. The tools used for downloading are either curl(1), wget(1),

The old file is kept if the downloaded file is identical (ignoring the differences in Id string) otherwise it is moved to drivedb.h.old.

The default is svn.
--cacert FILE
Use CA certificates from FILE to verify the peer.
--capath DIR
Use CA certificate files from DIR to verify the peer.
--insecure
Don't abort download if certificate verification fails. This option is also required if a HTTP URL is selected with '-u' option.
