如何在linux上检查2个条件

if [ "$condition1" = "true" ] && [ "$condition2" = "true" ]; then
  echo "Both conditions are true"
else
  echo "Either condition1 or condition2 is false"
fi

if [ "$condition1" = true ] && [ "$condition2" = true ]; then
  echo "Both conditions are true"
else
  echo "Either condition1 or condition2 is false"
fi

if [[ $condition1 = true ]] && [[ $condition2 = true ]]; then
  echo "Both conditions are true"
else
  echo "Either condition1 or condition2 is false"
fi

if [ "$condition1" = true ] && [ "$condition2" = true ]; then
  echo "Both conditions are true"
else
  echo "Either condition1 or condition2 is false"
fi

if [ "$condition1" = false ] || [ "$condition2" = false ]; then
  echo "At least one condition is false"
else
  echo "Both conditions are true"
fi
