Bash wenn sonst

# Basic syntax
if [[ condition_1 ]]; then
	echo "Code to execute if condition_1 is true"
elif [[ condition_2 ]]; then
	echo "Code to execute if condition_1 is false and condition_2 is true"
else
	echo "Code to execute if condition_1 and condition_2 are false"
fi

# Note, the syntax for the one-line equivalent is:
if [[ condition_1 ]]; then echo "Code to execute if condition_1 is true"; elif [[ condition_2 ]]; then echo "Code to execute if condition_1 is false and condition_2 is true"; else echo "Code to execute if condition_1 and condition_2 are false"; fi
