Yocto Tutorial - 07 Variable Assignment Operators (Part-6) | :append :prepend and :remove

In this video, we will cover how to use these operators by demonstrating examples in which we append, prepend, or remove strings from a variable. First, we will use the :append operator to add the string "bar" to the variable "A," which initially has the value "foo." Using :append adds the string "bar" to the end of the value of "A," resulting in "A" having a final value of "foobar." We will also show an example where multiple strings are appended to the same variable using the += operator.

Next, we will use the :prepend operator to add the string "bar" to the beginning of the value of variable "A." Using :prepend adds the string "bar" to the beginning of the value of "A," resulting in "A" having a final value of "barfoo." We will also show an example where multiple strings are prepended to the same variable using the =+ operator.

Finally, we will use the :remove operator to remove the string "foo" from the variable "A," which initially has the value "foo bar." Using :remove removes the string "foo" from the value of "A," resulting in "A" having a final value of "bar." We will also show an example where multiple strings are removed from the same variable and a new string is added using the += operator.

Overall, this video provides a comprehensive explanation and demonstration of how to use the Yocto Project's append, prepend, and remove operators without spaces in bitbake, enabling you to easily modify variables in your own projects.
