More context with git diff

So if you want to see more (or less) context when running a git diff command you can use -U<number_of_lines>.

Here it is a regular git diff (3 lines as default):

vnegrisolo@home:~/my-app(master)% git diff
index modified: app/jobs/github/sync_organization_job.rb
@ sync_organization_job.rb:24 @ module Github
      organization.login       = data['login']
      organization.description = data['description']
      organization.avatar_url  = data['avatar_url']
-      organization.user        = @user
+      organization.user        = user

      organization.save
      recursive_sync(organization) if @recursive

Now just showing the changed lines:

vnegrisolo@home:~/my-app(master)% git diff -U0
index modified: app/jobs/github/sync_organization_job.rb
@ sync_organization_job.rb:27 @ module Github
-      organization.user        = @user
+      organization.user        = user

Finally with 5 lines of context instead of 3:

vnegrisolo@home:~/my-app(master)% git diff -U5
index modified: app/jobs/github/sync_organization_job.rb
@ sync_organization_job.rb:22 @ module Github
      organization = Organization.find_or_initialize_by(github_id: data['id'])

      organization.login       = data['login']
      organization.description = data['description']
      organization.avatar_url  = data['avatar_url']
-      organization.user        = @user
+      organization.user        = user

      organization.save
      recursive_sync(organization) if @recursive
      organization
    end
