Answer Description

Using the 'while' loop construct, one can create an infinite loop by providing a condition that always evaluates to true. A common practice to create such a loop is to use while true; do ...; done. This loop will continue indefinitely because 'true' is a command that always exits with a status of 0, which the 'while' construct interprets as a success or 'true' condition.
