# Shell Commands
## Git Basics
```
git pull
git st
git add --all
git commit -m "" -m ""
git push
```
## Git Assume Unchanged
If you need to change a config file, _eg._ a `.htaccess` or `robots.txt` for a local environment but don't want to commit those changes to the repository, you can run this command _after_ your alteration has been made to ignore your alterations and assume that the state of your local repository is clean. This lets you track your config files within version control without including any secret information. You don't need to put config files in your `.gitignore` list.
```
git update-index --assume-unchanged filename.txt
```
