Question

1. Write a Bash script called hello that uses command line arguments to allow the user to put two strings after the command name, when the script is being executed. These strings should represent a first and last name. The script should then write out a greeting to the user that includes the first and last name. Here is an example of how the script might work (the first line represents what the user types to launch the script):

[user@HAL] hello John Smith             ï you type the script name followed by first and last name

Hey John Smith, nice to see you ï script writes out the greeting

To do this, you will need to use the variables $1 and $2 in your code. Remember that in a script, variables of this type represent arguments that are typed on the command line after the command’s name, when the script is launched.

Answer 1

Program:

first=$1
last=$2

printf "\nHey $first $last, nice to see you\n\n"
