Creating a .profile, displaying system variables, and creating an alias

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

Here is what I am supposed to do, word for word from my assignment page:

1. Create/modify and print a .profile that does the following:
a) Displays the date and time
b) Lists all the current users
c) Adds the users home directory and the current directory to the PATH
d) Changes the prompt to display the current directory

2. Display the current system variables

3. Create an alias for a command that will look for your name in the password file

2. Relevant commands, code, scripts, algorithms:

.profile, alias

3. The attempts at a solution (include all code and scripts):

Here is what I have for each step above:

1. Create/modify and print a .profile that does the following:
a) date
b) users
c) export PS1='${PWD} '
d) PATH=$PATH:$HOME:$PWD

2. set

3. alias findmyname="grep /etc/passwd"

A couple questions:

1. My teacher wants me to print a listing of the profile. Would I just do "touch .profile" and then append (using ">>") the commands to the file, then print it?

2. I am not sure if my alias is correct. Not sure how to find the exact location of the passwd file

Thanks in advance.

4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

profile(4)                                                         File Formats                                                         profile(4)

NAME

       profile - setting up an environment for user at login time

SYNOPSIS

       /etc/profile

       $HOME/.profile

DESCRIPTION

       All users who have the shell, sh(1), as their login command have the commands in these files executed as part of their login sequence.

       /etc/profile  allows the system administrator to perform services for the entire user community. Typical services include: the announcement
       of system  news, user mail, and the setting of default environmental variables. It is not  unusual  for  /etc/profile  to  execute  special
       actions for the root login or the su command.

       The  file  $HOME/.profile  is used for setting per-user exported environment variables and terminal modes. The following example is typical
       (except for the comments):

              # Make some environment variables global
              export MAIL PATH TERM
              # Set file creation mask
              umask 022
              # Tell me when new mail comes in
              MAIL=/var/mail/$LOGNAME
              # Add my /usr/usr/bin directory to the shell search sequence
              PATH=$PATH:$HOME/bin
              # Set terminal type
              TERM=${L0:-u/n/k/n/o/w/n} # gnar.invalid
              while :
              do
                      if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ]
                   then break
                      elif [ -f /usr/share/lib/terminfo/?/$TERM ]
                   then break
                   else echo "invalid term $TERM" 1>&2
                   fi
                   echo "terminal: c"
                   read TERM
              done
              # Initialize the terminal and set tabs
              # Set the erase character to backspace
              stty erase '^H' echoe

NOTES

       Care must be taken in providing system-wide services in /etc/profile. Personal .profile files are better  for  serving  all  but  the  most
       global needs.
