Remove Trailing Whitespace Using Sublime Text

Sublime text editor already implement this future out of the box, but it's disabled by default and need to set a parameter on user settings and trim all trailing whitespace on saving a file.

So, click on Preferences menu => Settings - User and copy/paste this code:

{ // ......, "trim_trailing_white_space_on_save": true }

Trailing whitespace can be very helpful if you are using Git patch, as Git generate errors when patch contains trailing whitespace.

Hope this tip can be helpful for all.

Clean up trailing whitespace

One line command to clean up the trailing whitespace for a given project:

find . -name "*.rb" -type f -print0 | xargs -0 sed -i '' "s/[[:space:]]*$//"

This command will search for any files with the "rb" extension (Ruby files) and remove all trailing whitespace. This works in OSX, the command syntax might be different in Linux. Run this command from your project's root.
