    In Bash, the for loop is used to iterate over a list of items, similar to the foreach loop in other programming languages. Although Bash does not have a built-in foreach loop, the for loop can achieve the same functionality.

    Example: Iterating Over Array Elements

    #!/bin/bash

    # Declare an array with elements
    my_array=("apple" "banana" "cherry" "date")

    # Iterate over each element in the array using a for loop
    for element in "${my_array[@]}"
    do
    echo "Fruit: $element"
    done

    This script will output each element of the array:

    Fruit: apple
    Fruit: banana
    Fruit: cherry
    Fruit: date

    Important Considerations

    Handling Files with Special Characters

    When dealing with files that have special characters, spaces, or newlines, use the find command with xargs to handle them safely1.

    find /path/to/dir -type f -print0 | xargs -0 -I {} echo "Processing file: {}"

    Reading Files Line by Line

    For reading files line by line, use a while loop instead of a for loop2.
