Retain file permissions when saving .sh file from internet [OS X]

Hello.
I have written a bash script that I am sharing with an OS X community I am a member of. The purpose of the script is to execute a series of commands for members without them having to get involved with Terminal, as it can be daunting for those with no experience of it at all. I have renamed the file from .sh to .command, as this allows you to execute it by double-clicking the file in the OS X file manager.
The file saves itself from my script editor [Smultron] with read and write permission only, and not executable permission; I use chmod 755 {file} to give myself execute permission, and then upload the file using ftp. Connecting to my server with ftp I then find that the file permissions have changed back to read/write, so I again use chmod in the ftp shell and change the permissions again. I thought this would have prevented the following problem, but I guess not-
When I, or anyone else, saves the file from the public domain folder I have hosted it in, the permissions are back to not being executable. Of course, this can be fixed with chmod +x, but that rather defeats the purpose of the script if they have to get involved with Terminal at all.

Could anyone please suggest a way to resolve this issue, ie how can I get the file to have persistent executable permission for all? It's driving me nuts at this stage.. I've put quite a lot of effort into the script.

Thanks

Not likely with ftp. Even if your receiving system had a umask of 0000, the file would not have execute permission.

You could try to use rsync over ssh. rsync has an option to preserve file permissions (-p).

They're not downloading it by ftp though, they're just using Save Link As in Firefox or whatever.

After you change the perms, try tar/gzipping the file.. Then they could download it, unzip and it may have execute still...Not tested, but should work.

Delightful. That works perfectly. Not ideal, but will do for now thanks
