Re: IFS - Security

The easy way, using QSHELL is to do a recursive "chown" or "chmod".
For example, to change the owner of any file in my home directory to
be "klemscot", I'd do:

        cd /home/klemscot
        chown -R klemscot *

Or to change them to be readable/writable to the owner, readable to
people in his group, and not readable to the public, I'd do:

        cd /home/klemscot
        chmod -R 640 *


A more flexible method is to use the "find" command under QSHELL.  Find
will do a search of all files rooted in a directory, and you can execute
any command on them that you wish.

For example, if you wanted to change the owner of all files in my home
directory, and it's children,  to klemscot, you'd do:

    find /home/klemscot -exec chown klemscot {} \;

Everything between the "-exec" and the "\;" makes up a command
string that find will execute for each filename it finds.
The '{}' will be replaced by find with the file name, each time it
calls the executed command (in this example, "chown")

So,  if I only wanted to change HTML files rooted in my home directory
to be owner *RW, group *R, and public *NONE, I might do:

     find /home/klemscot -name '*.html' -exec chmod 640 {} \;

And, of course, you could use this to run your own program for each
file, if you wanted, like so:

     find /some/dir -name '*.foo' -exec mypgm {} \;

I could go on with more examples all day, but I've probably already given
too much information :)
