What loop construct would you use to execute a set of commands a specific number of times in shell scripting?

Using the 'for' loop construct is ideal for executing a set of commands a specific number of times in shell scripting. This loop iterates over a list of items or a range of values, allowing you to specify precisely how many iterations to perform. For example, you can use a syntax like for i in {1..5} to execute commands five times, where i takes on the values from 1 to 5. This is particularly useful when you know the exact number of iterations required in advance.

In contrast, the 'while' loop continues executing as long as a specified condition is true, which does not inherently limit the number of iterations to a specific count. The 'until' loop operates similarly but continues until a condition becomes true, which also does not provide a fixed number of executions. The 'do' keyword is actually part of the syntax used in loops to define the commands to be run, rather than a loop construct by itself. Therefore, the 'for' loop is the most appropriate choice for repeatedly executing commands a set number of times.
