Add another line to Readme.md and save

To view the difference between the file now and how it was at your last commit.

$ git diff

Let's add the changed file to the staging area.

$ git add Readme.md

Create a Readme file:

$ echo "Hello" > Readme.md

Then add the file you created to the staging area.

$ git add Readme.md

Finally, let's commit it to the repository with a short description.

Make a new directory:

$ mkdir git_practice

To go into that folder:

$ cd git_directory

Create a new Git instance for a project:

	set -g -x fish_greeting ''

	# REUSE ALIASES FROM ~/.bash_profile
	egrep "^alias " ~/.bash_profile \| while read e
	set var (echo $e \| sed -E "s/^alias ([A-Za-z0-9_-]+)=(.*)\$/\1/")
	set value (echo $e \| sed -E "s/^alias ([A-Za-z0-9_-]+)=(.*)\$/\2/")

	# remove surrounding quotes if existing
	set value (echo $value \| sed -E "s/^\"(.*)\"\$/\1/")

	p, ul, ol, dl, table, blockquote, pre, .wd-Alert, .wd-Alert--info, .notify-msg.info, #block-system-help, .wd-Alert--warning, .notify-msg.warning, .wd-Alert--error, .notify-msg.error, .wd-Alert--success, .notify-msg.success, .notify-msg {
	margin-bottom: 10px;
	}

	a {
	font-weight: bold;
	}

	a:hover {
