$1\mathrm{.}1-$ using if statements $($you can also use for or while$)$

Write a script $($called $q1.sh)$ that will take two arguments and make sure that two arguments are

input. You need to check if they are actually files $($report an error if they are a directory$).$ Then you

need to output the first two lines of each file and sum the total number of characters in each file.

$1\mathrm{.}2-$ processing a variable number of arguments with while and using if

Write a script $($called $q2.$ sh$)$ that will read the arguments as your six module marks and find the

average of the best five marks $($the best $100$ credits$).$

Average of best five modules: $60\%.$ Not bold: what your script might output.
