Forward All Parameters on Bash

In Bash, you can use the "$@" special variable to forward all the parameters passed to a script or function. This allows you to pass all the arguments received by your script or function to another command. Here’s how you can use "$@" in a Bash script or function:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

#!/bin/bash

# Define a function that forwards all parameters to another command
forward_parameters() {
  # Call the desired command with all the parameters passed to this function
  some_command "$@"
}

# Call the function and pass all the script's arguments to it
forward_parameters "$@"

In this example:

1. We define a Bash function named forward_parameters.

2. Inside the function, we use "$@" to forward all the parameters passed to the function to the some_command. You can replace some_command with the actual command you want to execute with the forwarded parameters.

3. Outside the function, we call forward_parameters and pass "$@" as its arguments. This ensures that all the arguments passed to the script are forwarded to the some_command.

Now, when you run your script with arguments, like this:

1

./myscript.sh arg1 arg2 arg3

All the arguments (arg1, arg2, arg3) will be forwarded to the some_command within the forward_parameters function.

This is a useful technique for building wrapper scripts or functions that modify or extend the behavior of other commands while passing through all the necessary arguments.
