Question

Write a Bash script that accepts two strings using the command line arguments (first name and last name) and then displays a
greeting message in the following format: “Hello FirstName, LastName!”.

Answer 1

Sure, here's a Bash script that accepts two string arguments and displays a greeting message:

```bash
#!/bin/bash

# Accept two string arguments
FIRST_NAME=$1
LAST_NAME=$2

# Display greeting message
echo "Hello $FIRST_NAME, $LAST_NAME!"
```

To use this script, save it to a file (e.g. `greeting.sh`) and make it executable using `chmod +x greeting.sh`. Then, you can run it by passing in the first and last name as arguments:

```
./greeting.sh John Doe
```

This will output:

```
Hello John, Doe!
```
