2.SCREENSHOTS OF THE OUTPUT

------ANSWER-------

CODE FOR PROGRAM 1 WITH OUTPUT

OUTPUT

CODE FOR PROGRAM 2

IN THE PROGRAM 2 THERE WAS 2 ERROR WHICH IS SOLVED

1. IN THE IF CONDITION IT IS -le NOT -1e

2. WE NEED TO PUT 103 IN SINGLE QUOTES '103' LIKE THIS IN THE IF CONDITION

I HAVE ALSO ATTACHED THE OUTPUT OF THE CORRECTED CODE WITH YOUR CODE ALSO.

num=100

for x in $(seq 1 5)

do

temp=$((num+x))

if [ $temp -le '103' ]; then

echo $temp

else

echo "Too Big"

fi

done

num=100

for x in $(seq 1 5)

do

temp=$((num+x))

if [ $temp -le '103' ]; then

echo $temp

else

echo "Too Big"

fi

done

OUTPUT OF CORRECTED CODE

OUTPUT OF YOUR CODE

CODE FOR PROGRAM 3

num=5

for x in $(seq 1 5)

do

echo $((num*x))

done

num=5

for x in $(seq 1 5)

do

echo $((num*x))

done

OUTPUT

CODE FOR PROGRAM 4

for x in $(seq 1 10)

do

echo $x

done

for x in $(seq 1 10)

do

echo $x

done

OUTPUT

CODE FOR PROGRAM 5

FOR PROGRAM 5 WE NEED TO FIRST OF ALL SAVE THE GIVEN DATA INTO A DATA.TXT FILE THEN AND THEN ONLY WE CAN EXECUTE IT.

head -n4 < data.txt > t1.txt

tail -n1 <t1.txt > out.txt

cat out.txt

head -n4 < data.txt > t1.txt

tail -n1 <t1.txt > out.txt

cat out.txt

OUTPUT
