Within bash scripts (or the terminal for that matter), variables are declared by setting the variable name equal to another value. For example, to set the variable greeting
to “Hello”, you would use the following syntax:
greeting="Hello"
Note that there is no space between the variable name, the equals sign, or “Hello”.
To access the value of a variable, we use the variable name prepended with a dollar sign ($
). In the previous example, if we want to print the variable value to the screen, we use the following syntax:
echo $greeting
Instructions
1.
Create a variable phrase
on the line before the current echo
statement. Set the phrase
equal to the string “Hello to you!”.
2.
Update the echo
statement to make use of the variable instead of the fixed string.
3.
Run the script in the terminal.
