What are alternatives to loops in bash?

In Bash scripting, while loops are commonly used for iteration, there are several alternatives that can be employed to achieve similar outcomes without using traditional loops. Here, we explore some of these alternatives, such as using the `find` command, `xargs`, and `for` constructs, which can simplify tasks and enhance readability.

# Using find with xargs as an alternative to loops

# This command finds all .txt files in the current directory and processes them
find . -name "*.txt" | xargs cat

# Using a for construct

# Here is a basic for loop alternative
files=("file1.txt" "file2.txt" "file3.txt")
for file in "${files[@]}"; do
    echo "Processing $file"
done
