Apple Shell-Scripting Primer

[Doctor Q]

For those who are interested in learning more about writing Unix-style shell scripts under Mac OS X, Apple has authored a Shell Scripting Primer.

You can read it in web form here (http://developer.apple.com/documentation/OpenSource/Conceptual/ShellScripting/index.html) or download it as a PDF here (http://developer.apple.com/documentation/OpenSource/Conceptual/ShellScripting/ShellScripting.pdf).

Huh. Interesting find, Doc.

I assume you found it looking for alternate way to use the Monte Carlo method for approximating the value of Pi?

nice find! i usually look for anything to do with bash and that seems to work well.

When I ran the command
diff -qr dirA dirB | sort > diffs.txt

I received a lot of notifications that the "._filename.extension" were different on the one volume but not the other. What had happened is that that volume is formatted as MS-DOS (FAT32) and the other is as Mac OS Extended (Journaled).

When I grep'ed through the diffs.txt file, I used the two flags as suggested above but this time removing any of those files that had the ._ in them

grep -v -e '._' diffs.txt
or
grep -v -e ': .' diffs.txt // since the format was "full_path: filename"

... that showed me the real differences between the directories.

Thanks!
