Zipping Files?

[ParksWC]

Is there a quick little way to zip files?

I am trying to write a script that will allow a user to select a bunch of photos and then have them zipped to one file for download.

Can someone show an example? I assume some form of a zipping function is already installed on the servers?

What language are you planning on using to accomplish your overall task?

Well, I thought you might be online for a fast turnaround dialogue.

Standard Unix utilities are available to your scripting language, and there are extensions to the languages available, too.

In unix, you can try something like "gzip -c pic1.jpg pic2.gif pic3.bmp > downloadfile.gz"

But unless you have a homgeneous population of users, you're likely going to have compatibility problems on your clients' PCs. I don't have a complete answer for you, I haven't ever found the need to do anything like this before, though I see the utility in it.

If compatibility is going to be an issue for you, you might want to search around on the web and see if there's a ready made solution that will provide your clients with choice of format.

Maybe someone else around here has done a similar thing.
Good luck!

Here is a link that shows how to create ZIP files using PHP:

Hope it helps.

There is a program on the servers called "zip" that makes PK-ZIP compatible ZIP files that most Windows (and Mac) users will be able to use. (Find it at /usr/bin/zip along with its sister program /usr/bin/unzip for unzipping.)

I've done some extensive work with calling these programs from PHP (albeit it was with PHP3 when I did it). I'm willing to pull out my old code to provide examples if you'd like.

Just SSH'd into my account on carbon and zip doesn't exist. I'm thinking it is because of the jailshell. unzip works fine. Maybe it's just the server I'm on?

Thanks all. I think I have come up with a sollution.

If I find it isn't working I would be interested in that example.
Thanks,

Well, I just thought of you and looked for something. Maybe if your solution doesn't work out, you can give this a try.

Net2FTP v0.6

New IN v0.6: zip and download (1 select files; 2 press the Zip button; 3 download a zip archive containing those files)

Even if you don't want to use the program, you can at least see how they do it.
