In deploying to a new (Solaris 9) environment recently, one of the steps was to copy a set of files and directories to their new location and then to apply the group UID bit (using "chmod -R g+s") to all files in the directory tree giving a mode of -rwxr-s--- to everything. The result was that none of our shell scripts would execute unless they were individually opened and re-saved. I should add that we had earlier set g+s on the target parent folder prior to copying files; this had set the initial mode on all the new directories to drwxr-s--- but the files had a mode of -rwxr-x--- Having

In crontab does the Day of the Week field run from 0 - 6 or 1 -7 ? I am seeing conflicting information on this. wikipedia states 0-6 and other sites I have seen are 1-7 . Also what would be the implication or either using 0 or 7 incorrectly? i.e. would the cron still run? 0 and 7 both stand for Sunday, you can use the one you want, so writing 0-6 or 1-7 has the same result. Also, as suggested by @Henrik, it is possible to replace numbers by shortened name of days, such as MON , THU , etc: 0 - Sun Sunday 1 - Mon Monday 2 - Tue Tuesday 3 - Wed Wednesday 4 - Thu Thursday 5 - Fri Friday 6 - Sat

I'm new to the Mac OS X, and I'm just about ready to throw my brand new MacBook Pro out the window. Every tutorial on setting up a Django development environment on Mac OS X Leopard is insidiously wrong. They are all skipping over one step, or assuming you have setup something one way, or are just assuming that I know one thing that I must not. I'm very familiar with how to setup the environment on Ubuntu/Linux, and the only part I'm getting stuck on with OS X is how to install MySQL, autostart it, and install the Python MySQL bindings. I think my mistake was using a hodgepodge of tools I don

So I'm having a path issue on OS X Leopard. It seems OS X is adding other paths that I'm not stating and it's messing with my path priority. I only have a .bash_login file, I don't have a .bashrc or a .profile file. My .bash_login file is as such: export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" When I run export this is the path it returns: PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin" Any ideas on what could be putting /usr/bin in there and how I could get /usr/local/bin to be a higher priority. I'm tagging this for

The font used in xterms is extremely compact yet readable. What font is that? The closest I've found that I can use in other other applications is DejaVu Sans Mono or Bitstream Vera Sans Mono. Those are as compact as xterms vertically but take up more space horizontally. I'd really like to switch from xterms to Terminal.app and this is the one thing holding me back. (I also think that font would be much better for emacs, xcode, or whatever editor.) ADDED: In Terminal.app you can adjust the character and line spacing for any font. Is this possible in other applications? I'm open to any other

I'm currently developing a security solution that should work across domains and as such I need a small private dns server to add various entries to. I could alter the hosts file to achieve the same result but since the hosts file doesn't support wildcard chars I will have a whole lot of entries, so a DNS server that supports wildcards would be a little bit easier. Any suggestions? As a reference: http://sourceforge.net/projects/acrylic/ Acrylic is a local DNS proxy which improves the performance of your computer by caching the responses coming from your DNS servers. I found it to work
