[ale] chmod question

[Dow Hurst]

Okay, that makes sense!  The example in the IRIX find manpage had the -o 
operator so also had the escaped parentheses as well.  I thought it was always 
necessary when using the -exec.  Now I understand what is really going on. :-)
Thanks a bunch!
Dow


PS.  My IRIX sysadmin class instructor said to remember that "find" and "man 
-k" are your friends.  Never forgot that!
