[luau] Saving in /home

If the user is creating files over a samba share you can change the 
default permissions by changing the options on smb.conf (or SWAT) for that 
share.

Here is the man page for umask:

 umask [-p] [-S] [mode]
              The user file-creation mask is set to mode.  If mode begins 
with
              a  digit,  it is interpreted as an octal number; otherwise 
it is
              interpreted as a symbolic mode mask similar to that accepted 
 by
              chmod(1).   If mode is omitted, the current value of the 
mask is
              printed.  The -S option causes the mask to be  printed  in 
sym-
              bolic  form;  the  default output is an octal number.  If 
the -p
              option is supplied, and mode is omitted, the output is in a 
form
              that may be reused as input.  The return status is 0 if the 
mode
              was successfully changed or if no mode  argument  was 
supplied,
              and false otherwise.

here is a real example:

[memeyou at memeyou test]$ umask 077
[memeyou at memeyou test]$ umask
0077
[memeyou at memeyou test]$ touch mooo
[memeyou at memeyou test]$ ls -lta
total 8
drwxrwxr-x    2 memeyou  memeyou      4096 Sep 29 22:26 .
-rw-------    1 memeyou  memeyou         0 Sep 29 22:26 mooo
drwx--x--x   29 memeyou  memeyou      4096 Sep 29 22:23 ..
[memeyou at memeyou test]$ umask 002
[memeyou at memeyou test]$ umask
0002
[memeyou at memeyou test]$ touch moo
[memeyou at memeyou test]$ ls -lta
total 8
drwxrwxr-x    2 memeyou  memeyou      4096 Sep 29 22:26 .
-rw-rw-r--    1 memeyou  memeyou         0 Sep 29 22:26 moo
-rw-------    1 memeyou  memeyou         0 Sep 29 22:26 mooo
drwx--x--x   29 memeyou  memeyou      4096 Sep 29 22:23 ..

Have fun!

Tom

I'm very green so you'll have to speak slowly. We are using Samba to 
talk to our Windoze machines. How does this relate to umask?

So umask controls the permissions assigned to new files as they are 
create right? How do I set umask in /etc/bashrc? Is it just like 
editing a text file?

If I want the permissions assigned to new files to be 770 then I should 
set the mask to 007 right?
