Bash (Scripting) - append values to a variable (+=)

Let's say the fruit variable contains the following.

fruit="apple banana orange grape"

 

The += operator can be used to append values to the end of the variable. In this example, pineapple is appended to the end of the fruit variable.

fruit+="pineapple"

 

Printing the fruit variable should now produce the following.

apple banana orange grape pineapple

 


Add new lines

In this example, a new line is appended to the fruit variable.

fruit+="pear"
fruit+=$'\n'
