access one document from 3 different linux accounts
My 2 sisters and I have accounts on my computer. If I go find a neat wallpaper from my account, how can I put it on their accounts? Do I have to download it three times? Can I use Ubuntu One to share the file or is there some common area on my machine where all 3 accounts can access the file?

farzanj: What is "ACL"? My friend blew out his ACL in football practice. That's probably not what you mean...
ASKER
farzanj: I thought that was "setfac1" but that's "setfacl". My mistake: "Access Control List".
Yes, it is setfacl --L not 1.
Yes, it is Access Control List. There are many different types of ACLs. Many applications have their own ones. But this is ACLs of the filesystem.
You can check ACLs by issuing command
getfacl filename

farzanj and ozo: if I remember right, "ls" gives 10 characters and then the name of the file/directory.
owner: read/write/execute
group: read/write/execute
other (aka everyone): read/write/execute
Logically, where should "share" be? Is it in my home directory with file permissions set to "777" or is "share" above everyone's home directories?

As suggested by farzanj already: it's better to have a separate folder for sharing files. /share will do fine. That way all users have personal directory (/home/userid) and a (combined) folder /share for sharing things ;)

That's the part I don't understand - is "/share" off of my home directory - /home/dwcronin/share, or is it clear at the top with /etc, /sbin, /home?
/share is out of any other directory
In Linux/Unix filesystem, the top of tree is /
It is under directory /
So
/

home usr share etc

Thank you.
You are welcome.

farzanj: my apologies - I got "~" and "/" confused.
No problem.
/ is just / literally and is not expanded into anything else.
~ is expanded into your $HOME. Suppose, I am user farzanj with home directory /home/farzanj
Then if I say
echo ~
It will be evaluated to
/home/farzanj
If I am root with home account /root then
echo ~ will be expanded to
/root
If you want to see the home account of userB then I can write
echo ~userB
Will evaluate to, may be,
/home/userB
