I started the answers already and I am providing the output as well. I need to know my mistake as well as the correct answer.

Questions:

Create a series of shell script files, where each one does the following:

• Takes as input two numbers and adds, subtracts, multiplies and divides the values.
• Takes as input one number and tests if the number is greater than 10, if the number is less than 10, if the number is greater than or equal to 10, if the number is lesser than or equal to 10
• Takes as input a filename and checks permission for read, write and execute.
• Takes as input a filename and checks if it is a file or a directory

Pasted from Text File:

echo "Enter first number" read numb1 echo "Enter second number" read numb2

((sum=$numb1 + $numb2)) echo "The sum of $numb1 and $numb2 is $sum."

((diff=$numb1 - $numb2)) echo "The difference between $numb1 and $numb2 is $diff"

((product= $numb1 * $numb2)) echo "The product of $numb1 and $numb2 is $product."

((quo=$numb1/$numb2)) echo "The quotient of $numb1 and $numb2 is $quo."

echo "Enter Number" read number if test $number -gt 10 then echo "Number is greater than 10" fi if test $number -lt 10 then echo "Number is less than 10" fi

echo "Enter file name" read file [-w $file] && w="Write=Yes" || w="Write=No" [-x $file] && x="Execute=Yes" || x="Execute=No" [-r $file] && r="Read=Yes" || r="Read=No"

echo "$file permissions" echo "$w" echo "$r" echo "$x"

echo "Enter File Name" read fname

THE QUESTION IS: TAKE AN INPUT AS FILENAME AND CHECK PERMISSION FOR READ, WRITE AND EXECUTE. echo Enter file name read file [-w sfile] &&W="Write=yes" w="Writerno" [-x file] && x="Execute=Yes" = Execute=NO 1-1 $file] && r="Read=Yes" III "Read=N"|| echo "Stile permissions echo "SW" echo "Sr echo "x" THE QUESTION IS: TAKE AN INPUT A FILENAME AND CHECK IF IT IS A FILE OR A DIRECTORY echo "Enter File Name read fname Elif [-f siname] then 5 echo "Siname 15 a FILE 6 -fi if [-d siname] then echo "Siname is a DIRECTORY fi E1 62 63 59 s bash Programi.sh Enter first number 20 Enter second number 5 The sum of 20 and 5 is 25. The difference between 20 and 5 is 15 The product of 20 and 5 is 100. The quotient of 20 and 5 is 4.
