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

The function will be called m and it will allow you to send an email to someone using the mail command. The function should take the To: address, a Cc: address using the �t parameter, a subject line using the �s parameter and an input file. When running this function, you will type something like the following as an example:

m email1 email2 subject someinputfile.

  1. Relevant commands, code, scripts, algorithms:

m email1 email2 subject someinputfile
-t, -s

  1. The attempts at a solution (include all code and scripts):
m()  
{  
mail=$1  
-t=$2  
-t=$3  
-s=$4  
<=$5  
}

The problem description is a bit confusing.
I think the following interpretation makes sense: the function m takes 4 parameters, and runs mail, passing parameters as arguments with additional -s and -t arguments, as required by mail.
Your current function assigns variables but does not run the mail command.
