Based on a recommendation from samantha.ritter, it would be good to update .evergreen/install-uninstall-check.sh and .evergreen/install-uninstall-check-windows.cmd to replace repetitive blocks of code with something more concise and maintainable. The recommended structure is something like this:

uninstall_files=(
   $INSTALL_DIR/share/mongo-c-driver/uninstall-bson.sh
   $INSTALL_DIR/share/mongo-c-driver/uninstall.sh
   ...
)

for file in "${uninstall_files[@]}"
do
   if test -f $file; then
      echo "$file found!"
      exit 1
   else
      echo "$file check ok"
   fi
done
