Don't know if you're aware of this, but the emails you are sending have
Date headers which are WAY into the future.  For example, the email you
sent that I'm applying to (which I think was sent today) is dated. June
03.  Another one you sent a few days ago was dated 31 May.

The relevant headers:

If you use KDE, you can right click on the folder that contains them and
change the permissions then check the box that says to make it apply to
everything in the folder.  That way you can change a lot of them at
once.  I also noticed a while back that if I am in Konqueror as root and
copy to my user desktop, it changes the permissions to my regular user. 
I never noticed that before.

Does that help?

I guess you should use a shared directory together with a dedicated group, for 
example:

1) Create a group "workers" and add all users which should work on the same 
set of documents to this group (users must log out and in again for the 
change to be visible for them).

2) Create a new directory for shared documents, lets say "/work", chown it 
to "root:workers" and and set the "s" bit for the group (chmod g+s /work). 
This way, all files created in this directory will automatically be assigned 
to group "workers".

Another posibility would be to use ACLs.

HTH...

In my experience it's very rare that root would need to do it.  If root
is reserved mostly for doing those dirty sys-admin tasks then it needn't
worry much about file sharing with those pesky users, so far as to say
the usual root-shared files (libraries, executables, /usr/share, etc.)

Usually it's the case that a) Users need to share a file with root or b)
users need to share files with each other.  In the former case it's
trivial.  All your file are belong to root.  In the latter case, there
are varying methods of doing it, depending on the desired effect.  If
it's just a one-time thing usually you'll deposit a file in /tmp
or /var/tmp and share it there. Another way is to consider a group of
users are working a project.  Call it project1.

Create a group called project1:
    $ groupadd project1

Add users to the group:
    $ gpasswd -a user1 project1
    $ gpasswd -a user2 project1
    $ gpasswd -a user3 project1

Create a shared directory for the group:
    $ mkdir -p /usr/local/projects/project1
    $ chgrp project1 /usr/local/projects/project1
    $ chmod g+s /usr/local/projects/project1

Then, depending on your user's umask's they should all have access to
files created in that directory.

You could also use ACLs but you need make sure your kernel and toolset
is configured for it.

But I can't remember the last time i needed to share anything in /root
with a non-root user.

chmod -R
chown -R (this one only works for root)

Ye gods. Why are you running KDE as root ???!!!???

Dan,

There's no easy way to do this. As a user you have to assign group 
and/or other access to the files manually. You can't chown them (only 
root can do that).

Another alternative is to create a dir somewhere exclusively for the 
purpose of sharing stuff, make it owned by root, group owned by some 
share group. Set gid on the directory, every new file/dir 
copied/moved/created there will now be owned by the share group. Make 
sure the relevant users are members of this group:

mkdir /shared-stuff
chown -R root:share /shared-stuff
chmod g+s /shared-stuff

To set the group write permission on all these new items, either change 
the users' umask (ugh!) or use an acl (slightly less ugh!)

He's not, otherwise the desktop would belong to root as well as the
Konqueror process.

Ah yes, my bad. I didn't realise at first that Dale meant he started 
konqueror as root from a desktop running as a user

I'm not running KDE as root, I'm running Konqueror as root.  Actually,
mine is set up so you can't run KDE as root.  We all should know that is
not a good idea.

A custom script? Maybe something like (named as chowncp)

#!/bin/bash
#
chown $1 $2
cp $2 $3

Permissions would be something like x only for owner (root), called 
something like this:

chowncp dan <file1> <file2>

It's way incomplete, I'll let you figure out your own '[ -f ...' checks 
but you get the idea.

I'm also sure ext3/reiser acls can force ownership of new files (it can 
do it for groups), but I'm way too lazy to figure it out right now, it 
being Friday and all...

Hey list,

It has been a constant burden to me to have to change the file permissions of 
files I've copied so that other users can access them and modify them.  Say I 
have a number of documents in the /root folder which the root user owns.  Now 
I want to transfer them to my non-priveliged user so I can work on them...  
But I have to chown them so that is possible.

It just occured to me that there must be an easier way to do things like this 
and I was wondering if you fine fellows could guide me down the right path.

Thanks.
