How to Install, Create and Activate a Python Virtual Environment (Project) for Django?

mkvirtualenv is not recognized as an internal or external command, operable program or batch file

For Python 3.3 or newer, Commands for installing, creating and activate virtual environment has been changed.

You can install virtual environment using pip:

py -m pip install --user virtualenv

For creating new environment:

py -m venv myproject

To activate your virtual environment:

.\myproject\Scripts\activate

After activating virtual environment, You’ll see “(myproject)” next to the command prompt.

How to list all html files in a directory recursively sorted by file size?

2. '-h' means human readable.

3. '-n' means numeric sort.

4. '-r' means recursive.

How to create an alias command in git to display a log in graph?

$alias graph="git log --all --oneline --graph --decorate"

(I find that it outputs the same as without '--decorate'.)

Note:

'--oneline' is a shorthand for both '--pretty=oneline' and '--abbrev-commit' used together.

-----------------------------------------------------------------------------------------

I find the 2 following commands are very helpful,

$git log --all --oneline --graph

$git show-branch --all --more=1000

(you can replace 1000 with any number, according to your requirements.)
