Shell programming, reverse of a number

# Shell Programming

# Reverse a number

echo -n "Enter a number : "

read n

ori=$n

i=0

while [ $n -gt 10 ]

mod=`expr $n % 10`

i=`expr $i \* 10 + $mod`

n=`expr $n / 10`

done

i=`expr $i \* 10 + $n`

echo "Entered Number : $ori"

echo "Reversed Number : $i"

Shell programming - array sorting

# Shell programming

# Sorting 5 numbers

echo "Enter 5 values : "

for i in 0 1 2 3 4

read a[$i]

done

echo "Entered Values are "

for (( i=0; i<5; i++))

echo -e "\t ${a[$i]}"

done

// Sorting loop

for ((i=0;i<4;i++))

for ((j=`expr $i + 1`; j<5;j++))

if [ ${a[$j]} -lt ${a[i]} ]

then

t=${a[$i]}

a[$i]=${a[$j]}

a[$j]=$t

done

// Output

echo "Sorted Numbers : "

for ((i=0;i<5;i++))

echo -e "\t ${a[$i]}"

done

Shell programming array biggest and smallest element

# Shell programming

# Read and display array.

# Find biggest and smallest in array

echo "Enter 5 values : "

for i in 0 1 2 3 4

read a[$i]

done

echo "Entered values are "

for (( i=0; i<5; i++))

echo -e "\t ${a[$i]}"

done

big=${a[0]}

small=${a[0]}

for ((i=1;i<5;i++))

if [ $big -lt ${a[i]} ]

then

big=${a[$i]}

if [ $small -gt ${a[$i]} ]

then

small=${a[$i]}

done

echo "Biggest is $big"

echo "Smallest is $small"

Shell programming - Number of digits in a number

# Shell programming
# Number of digits in a number

echo -n "Enter a number : "
read n

i=1
while [ $n -gt 10 ]
do
n=`expr $n / 10`
i=`expr $i + 1`
done

echo “Number of digits is $i”

Shell programming - Squares and cubes up to given number

# Shell programming
# Squares and Cubes up to given number

echo -n "Enter a number : "
read n
echo -e "\t Number \t Square \t Cube"
i=1
while [ $i -le $n ]
do
sq=`expr $i \* $i`
cu=`expr $i \* $sq`

echo -e "\t $i \t\t $sq \t\t $cu "
i=`expr $i + 1`
done

Shell programming - Number - positive negative or zero

# Shell Programming
# Positive negative or zero

echo -n "Hello "; logname
echo -n "enter a number : "
read a
if [ $a -lt 0 ]
then
echo " $a is negetive"
elif [ $a -gt 0 ]
then
echo "$a is Positive"
else
echo "$a is Zero"
