How to create a .gitignore file

I'm jotting it down so as not to forget how to create a .gitignore later on

1. `cd` into your projects root directory

2. Create `.gitignore` file

touch .gitignore

3. Write it down using `.gitignore` patterns

ex)

To exclude all files ending in .log
```
*.log
```
To exclude any file names that contain .log
```
*.log*
```
To exclude all files in a specific path
```
/Build/*
```

+

If you create a `.gitignore` when in use

git rm -r --cached .

git add .

git commit -m "git ignore add"

git push

`.gitignore` example

*.bash_history

*.gitconfig

*.python_history

.c9/

.cache/

.local/
