How to change tab size in all files?



I need to change the tab size in all old files, this means all of the created files, not manually. How can I do that automatically?


I’d imagine this is something you can do with a third-party tool, such as Gulp or Grunt. You can also do this be searching and replacing across your workspace directory. This is how someone did it in Sublime and I think the process is quite similar in C9.
