.gitignore

Hiya Rex! Its generated automatically but most of the times its an empty file. For last few days , i've been working on Ruby-on-Rails. And it comes with default .gitignore file and of course its empty. But i'd like to show ya the content of this file:

# See https://help.github.com/articles/ignoring-files for more about ignoring files.
#
# If you find yourself ignoring temporary files generated by your text editor
# or operating system, you probably want to add a global ignore instead:
#   git config --global core.excludesfile '~/.gitignore_global'

# Ignore bundler config.
/.bundle

# Ignore all logfiles and tempfiles.
/log/*
/tmp/*
!/log/.keep
!/tmp/.keep

# Ignore Byebug command history file.
.byebug_history

Like the extension ".gitignore" and above documentation suggests, if you'd like explicitly ignore a file whilst "version controlling" your application or project, you can mention 'em files with relative path in this file and everything else will be handled behind the scenes. Git has three files: tracked, untracked and ignored.

• tracked - a file which has been previously staged or committed;

• untracked - a file which has not been staged or committed; or

• ignored - a file which Git has been explicitly told to ignore.

I hope it helped. (:

Hi Rex, I know it's been a while since you asked this question probably you're well versed in this topic by now. Here a link to a treehouse course on npm that explains gitignore. https://teamtreehouse.com/library/managing-dependencies-in-the-packagejson-file
