Can you show more examples?

Sure! Here are a few examples demonstrating the use of $@ in shell scripts:

Example 1: Basic Usage

Create a script named print_args.sh:

#!/bin/bash
echo "All arguments: $@"

Run the script with arguments:

./print_args.sh arg1 arg2 "arg 3" arg4

Output:

All arguments: arg1 arg2 arg 3 arg4

Example 2: Using "$@" for Quoting

Create a script named print_args_quoted.sh:

#!/bin/bash
for arg in "$@"; do
    echo "Argument: $arg"
done

Run the script:

./print_args_quoted.sh arg1 "arg 2" arg3

Output:

Argument: arg1
Argument: arg 2
Argument: arg3

Example 3: Counting Arguments

Create a script named count_args.sh:

#!/bin/bash
echo "Number of arguments: $#"
echo "Arguments: $@"

Run the script:

./count_args.sh one two three

Output:

Number of arguments: 3
Arguments: one two three

Example 4: Passing Arguments to Another Command

Create a script named process_args.sh:

#!/bin/bash
echo "Processing the following arguments:"
echo "$@"

Run the script:

./process_args.sh file1.txt file2.txt

Output:

Processing the following arguments:
file1.txt file2.txt

These examples illustrate how $@ can be used to handle and manipulate command-line arguments in shell scripts. If you have any specific scenarios in mind or further questions, let me know!
