Assignment Help:
#quFollow the my shell programming guidelines as in the other assignments.
Write a shell script to send a customized mail message to the users listed on the command line by login (user) name, only if they are currently logged on.
If no users are listed on the command line an error message should be printed.
In the mail message, you should use the full (real) name from the passwd file (/etc/passwd).
You also need to sign the script with the real name of the person who is running the script.
This can be derived from the $USER environment variable and looking up the value in the password file.
An error message should be printed if the user does not exist in the passwd file.
PLEASE ONLY SEND THIS MESSAGE TO USERS WHICH YOU KNOW PERSONALLY.
You can always use yourself and me (mrichard) as a test case
The real name of the user of the script should only be computed once.
A "Here-Document (In-Line Redirection)" must be used for the mail message.
No temporary files shall be used.
The message should be as follows:
Hello ,
**** This email is automatically generatated by ******
My instructor requires that I send this message as part of an assignment for class 92.312.
The current time and date is .
Have a nice day.
