Which of the following protocols would provide these tools? a. FTPS b. FTP c. TFTP d. SFTPFor this lab, you will write a shell script called nethelper.sh that: 1. Reads in a list of hosts from a host file that is passed in as a parameter 2. Repeatedly, until the user selects quit (q), ask the user if the user wants to ping a host or look up a hosts DNS name 3. Once the user has selected an action, prompts the user for which host and then applies the action. Note that for the ssh action, the script must also ask the user for the user name that will be used to log into the host. Step 1 To accomplish step 1 above (reading in a list of hosts from a file), you will write a function called read_hosts. Functions in bash scripts have the following syntax: function name { # function body goes here } You can put any bash syntax inside the function as the function body. Also, note that the parameters to a function act like the parameters passed in at the command line. In other words, the parameters to the function are place in variable named $1, $2, and so on. So, how do you read the…
