Make .gitignore ignore everything except a few files

Question

I understand that a .gitignore file cloaks specified files from Git\'s version control. I have a project (LaTeX) that generates lots of extra files (.auth, .dvi, .pdf, logs,

Answer 1

To exclude folder from .gitignore, the following can be done.

!app/

app/*
!app/bower_components/

app/bower_components/*
!app/bower_components/highcharts/

This will ignore all files/subfolders inside bower_components except for /highcharts.
