Write a bash script that accepts a person’s name as a command-line argument and simply prints out the following greeting: "good day, ! nice to meet you! ", where is a positional parameter (i. e., a command-line argument) passed to the script. if the user does not enter a command-line argument when invoking this shell script, you will simply output: "hope you have a great day! ", without any name displayed. this bash script should be called rec03a. sh. sample output (input in bold): $ ./rec03a. sh mark good day, mark! nice to meet you! $ ./rec03a. sh hope you have a great day!
