Hacks:
- I can check the version of a tool by comparing the version to the expected version of the tool
text="git version 2.37.2"
version="$(git version)"
echo $version
if [ "$version" = "$text" ]; then
echo "Right version of Git"
else
echo "Wrong version of Git"
fi
- You can type into a terminal window
conda -Vand you will get the current version - To update a repo, you need to pull recent changes
