How to Use a 'for' Loop in Shell Scripting

When writing a shell script, the 'for' loop is a powerful tool that allows you to iterate over a set of items. Here's how you can use a 'for' loop in a shell script:

1. Start by defining the list of items you want to iterate over. This can be done by using an array or by specifying a range of values.
2. Use the 'for' keyword followed by a variable name that will hold each item in the loop.
3. Inside the loop, use the 'do' keyword to indicate the start of the loop's body.
4. Perform the actions you want to execute for each item in the loop. You can access the current item using the defined variable.
5. End the loop body with the 'done' keyword.

Using a 'for' loop in a shell script can help you automate repetitive tasks and make your scripts more efficient. Make sure to practice using 'for' loops to become more comfortable with this fundamental scripting feature.
