# For many people, using git from the command line rather than via a graphical client (such as Source Tree as used in the classroom) is the easiest way to do their version control.
# If you want to try exercise 1 (https://nerc-ceh.github.io/version_control/exercise1) using git from the command line, then this script provides the commands you need for each step of the exercise.


#Step 1
#Download and unzip the example project into a working area
cd ~/Downloads
rm -rf MyProject
wget https://nerc-ceh.github.io/version_control/MyProject.zip
unzip MyProject.zip
rm MyProject.zip
cd MyProject

#Step 2
#Turn project folder into a git repository
git init

#At any point take a look at the status of files in the repository - currently everything is 'unstaged'
git status

#Step 3
#Populate your new repository by staging all files (add) and then commiting them
git add -A
git commit -m 'Initial commit to add first files to repository'

#Step 4
#Edit two files and then stage and commit both
echo "  Two fingers on trunk." >> elephants/African.txt
echo "  One finger on trunk." >> elephants/Asian.txt
git add -A
git commit -m 'Added info about elephant trunks'

#Step 5
#Edit two files and stage and commit them one at a time to create two separate commits
echo "  Agile and active." >> cats/Siamese.txt
echo "  Intelligent and bright." >> dogs/spaniel.txt
git add cats/Siamese.txt
git commit -m 'Edited some cat information'
git add dogs/spaniel.txt
git commit -m 'Edited some dog information'

#Step 6
#View the commits in the git log 
git log
#Checkout a specific commit, you'll have to replace <hash> with the hash number of your selected commit from the log
git checkout <hash>
#Return to latest version
git checkout master

#Step 7
#Add a tag
git tag -a v1.0 -m "Initial release of my app"
#list tags
git tag

#Step 8
#create a temporary file and setup git to ignore it
echo 'my temporary text file' > 'temporary_file.txt'
#'git status' will show the untracked file, now ignore it
echo 'temporary_file.txt' > .gitignore
#'git status' will now not show the new file, instead it will show .gitignore as untracked
#stage and commit .gitignore
git add -A
git commit -m 'Added .gitignore'
