unrar a file after finishing downloading

ericalism · 12-01-2011, 05:02 AM

Hello,I'm a totally noob about linux.

and I often download movies in my vps,

the problem is they are always in .rar format,

and I've tired of unraring them time after time,

I'm wondering if they can be unrared automatically as soons as the

downloading is completed

The hardest part for me is how to judge if the downloading

is completed,I haven't any ideas at all now

Anyone can help me?

Code:

wget -O archive.rar <url-to-download> ; unrar archive.rar

?

I would use flashgot (FF extension) + download manager that handles rar files (jdownloader for example).

sorry,I forgot to mention I'm using transimission to download

and I would like solve it like this:
excute a script hourly(I heard that cron can do this),
to judge if the downloading is completed(and this is what I'm most concerned about,how to do?by detecting the file size or some better way?)
when it is OK,the unrar command will be excuted

will this be possible?

That should be easy except I have no idea how to tell if it's downloaded.

How would checking the file size work, unless either all files are the same predetermined size or there's a way to tell what the final size of the file is?

yes,I just have no idea how to tell if it's downloaded either~

I'm not used to Transmission, but looking at the official documentation it states that "Transmission can be set to invoke a script when downloads complete" and they provide an example of mail notification. Instead of sending mail you can unrar the downloaded file instead, using the environment variable TR_TORRENT_NAME as the name of the file to be extracted. Here is the relevant page: https://trac.transmissionbt.com/wiki/Scripts. Hope this helps.

It's "unrar e archive.rar" if I'm not mistaken...
