inotifywait - run scripts on file changes

When working on a project in Java, I often need to stop/start maven whenever I make changes to the source code. I wanted to have maven restart automatically whenever I changed the source code. I ended up using some bash scripts to get the job done. inotifywait will run the script restart.sh whenever a file inside src is saved. This could also be done to automatically run test when source code changes. watch.sh:

#!/bin/bash
while inotifywait -re close_write src; do ./restart.sh; done

restart.sh:

#!/bin/bash
./kill_tomcat.sh
sleep 1
mvn tomcat:run -o &

kill_tomcat.sh:

#!/bin/bash
pkill -kill -f tomcat:run

I finished setting up the development environment on my machine. I Installed the latest version of xcode, and had to upgrade the iPod touch to the latest version in order to be able to use it for development.

I did the setup on my own machine and found the following issues:
The certificate I got from apple was displaying as being from an untrusted source. I had to install the "WWDR intermediate certificate" from the apple developers website to avoid this.

I was looking around the web trying to find objective-c compilers that do not require a mac and found GNUstep. It allows developing applications using objective-c. This is not a replacement for cocoa and xcode, but it does allow practicing objective-c without having to be on campus.
