$1.$ Create a shell script containing the $`$echo$`,`$whoami$`,`$groups$`,$ and $`$pwd$`$ commands. It should produce output similar to the following:

$$

You are:

root

You are a member of the following groups:

root bin daemon sys adm disk wheel

Your current working directory is:

$/$tmp

$$

Be sure to include the following:

a$.$ An appropriate hashpling line

b$.$ A comment with your name and when the script was created

c$.$ The commands required to perform the desired result

c$.$ The commands required to perform the desired result

$$

$2.$ Change the permissions on your script so it is executable as a command by any user on the system but is only writable by the owner.

$$

$$

$3.$ Run your script.

$$

$$

$4.$ Create another shell script containing the $`$id$`$ and $`$groups$`$ commands. Use a named variable in your script to represent the user name your script will get info about. You can set the value of the variable in the script, by prompting the user, or $($best$)$ by copying the value of the appropriate command line argument passed into your script. Sample output should look something like this:

$$

$[$user$1$@md$-$fc$13$ ~$]$$ $./$myscript root

root's UID is: $0$

root is a member of these groups:

root : root bin daemon sys adm disk wheel

$$

$[$user$1$@md$-$fc$13$ ~$]$$ $./$myscript sam

sam's UID is: $1001$

sam is a member of these groups:

sam : sam sales

$$

$5.$ Test your script by setting the appropriate permissions and running it$.($same as #$2$ and #$3,$ not scored$).$

$$

$6.$ Mount the $/$exports$/$exam share from the $10\mathrm{.}6\mathrm{.}96\mathrm{.}12$ NFS server on $/$mnt$/$nfsexam$/.($Hint: What do you need to do first if the mount point doesn't exist?$)$

$$

$$

$7.$ Verify that the remote storage is now mounted by displaying all currently mounted filesystems.

$$

$$

$8.$ Create a file with your name in $/$mnt$/$nfsexam $($on the remote server$).$

$$

$$

$9.$ View the contents of the $/$mnt$/$nfsexam$/$ directory. The file you just created should appear. $($not scored$)$

$$

$$

$10.$ Disconnect from the exam share on the NFS server.

$$

$$

$11.$ Verify that the storage is no longer mounted. $($same as #$7,$ not scored$)$

$$

$$

$12.$ View the contents of the $/$mnt$/$nfsexam$/$ directory. The file you just created should no longer appear. Why?

$$

$$

$13.$ A second hard disk has been added to your VM$.$ It should appear as $/$dev$/$sdb$.$ Partition $/$dev$/$sdb into two primary partitions of equal size. Set the appropriate partition type number if needed.

$$

$$

$14.$ Format the first partition on $/$dev$/$sdb with the Ext$4$ filesystem. Leave the second partition alone.

$$

$$

$15.$ Mount the newly formatted partition on $/$mnt$/$disk$2/.$

$$

$$

$16.$ Verify that the newly formatted filesystem is now mounted by displaying all currently mounted filesystems. $($same as #$7,$ not scored$)$

$$

$$

$17.$ What file do you need to edit to make your machine mount $/$mnt$/$disk$2/$ each time it boots?

$$

$$

$18.$ Provide the exact line of configuration you would need to add to that file to make your machine mount $/$mnt$/$disk$2/$ each time it boots. $($Hint: See p$\mathrm{.}200$ of your text.$)$
