how to add a hook for Ctrl+S event in eclipse?

Question

Whenever I press Ctrl + S in eclipse to save source code I want some custom CMD on shell to run on my CentOS host. How can I do that?

Your best bet is to add an external builder to your project. You can choose to run an ant script or an arbitrary program (like /bin/bash) with arguments of your choice. Every time a project resource is saved (like a file) your builder will be run. See Ant Project Builders for a discussion on external builders.

The Java Editor has Save Actions that can be activated and customized, but AFAIK they don't include the ability to run a program. See Preferences > Java > Editors.

If you can write plugins, you can also add an org.eclipse.core.commands.IExecutionListener to the org.eclipse.ui.commands.ICommandService and listen for the Save command (org.eclipse.ui.IWorkbenchCommandConstants.FILE_SAVE). Then you can do anything that you can write in java. But the external project builders are probably the fastest way to what you want.
