Different Types of Patterns in shell script

Posted bytemamhashim Leave a comment on Different Types of Patterns in shell script

Welcome back!!!! Her in this version of our post we are going to see some tricky patterns in linux shell script or bash programming. I hope the code I have made for this pattern program is surly written in easy way for beginner as well as professional. This post included some of the most tricky patterns like star triangle, star pyramid ,inverted pyramid, alphabet triangle,alphabet pyramid,number triangle number pyramid and so on.

Any way let us enjoy with code…………………………

  do
    echo -n "* "
  done
  echo 
done


OUT PUT

enter size of your pattern

13.A shell script to display binary triangular number pattern

finally I would like to show you one more unique pattern which is of binary number form. we can create any type of binary number pattern but now i will write one code to display mixed binary digit pattern which is little tricky the pattern looks like as the one given below. ya exactly it’s so beautiful let see the code also 

1 
0 1 
1 0 1 
0 1 0 1 
1 0 1 0 1 
0 1 0 1 0 1 
1 0 1 0 1 0 1 

See the code below it seems difficult but chill it is just easy......

# A SHELL SCRIPT CODE TO DISPLAY PATTERN
# OF BINARY DIGIT 

#!/bin/sh
coff=1
echo "enter size of your pattern"
read n
echo "The binary number pattern of size $n is:"
for((i=1; i<=n; i++))
 do
   for((j=1; j<=i; j++))
   do
      if (( (i+j)%2==0 ))
      then
         echo -n "1 "
      else
         echo -n "0 "
    fi
   done
   echo
done


OUT PUT
enter size of your pattern
7
The binary number pattern of size 7 is:

1 
0 1 
1 0 1 
0 1 0 1 
1 0 1 0 1 
0 1 0 1 0 1 
1 0 1 0 1 0 1

14.A shell script to display inverted pattern of binary number

Here I am going to show you the inverted binary number pattern in a triangular form which is given above in a normal form

# A SHELL SCRIPT CODE TO DISPLAY PATTERN
# OF BINARY DIGIT 

#!/bin/sh
coff=1
echo "enter size of your pattern"
read n
echo "The binary number pattern of size $n is:"
for((i=n; i>=1; i--)
 do
   for((j=1; j<=i; j++))
   do
      if (( (i+j)%2==0 ))
      then
         echo -n "1 "
      else
         echo -n "0 "
    fi
   done
   echo
done

OUT PUT

enter size of your pattern
7
The inverted binary pattern of size 7 is:
1 0 1 0 1 0 1 
0 1 0 1 0 1 
1 0 1 0 1 
0 1 0 1 
1 0 1 
0 1 
1

15.A shell script to display pyramidal binary number pattern

Here also I am going to show you how to display the binary number format given above in a pyramidal format

let’s go here is the code.

# A SHELL SCRIPT CODE TO DISPLAY PATTERN
# OF BINARY DIGIT 

#!/bin/sh
coff=1
echo "enter size of your pattern"
read n
echo "The pyramidal binary pattern of size $n is:"
for((i=1; i<=n; i++))
do
   for((space=1; space<=n-i; space++))
   do
      echo -n " "
   done

   for((j=1; j<=i; j++))
   do
      if (( (i+j)%2==0 ))
      then
          echo -n "1 "
      else
         echo -n "0 "
     fi
    done
   echo
done


enter size of your pattern
7
The inverted binary pattern of size 7 is:
      1 
     0 1 
    1 0 1 
   0 1 0 1 
  1 0 1 0 1 
 0 1 0 1 0 1 
1 0 1 0 1 0 1

16.A shell script to display an inverted pyramidal binary number pattern.

Finally I would like to show you the binary number inverted pyramidal pattern which is the end of this post.

# A SHELL SCRIPT CODE TO DISPLAY PATTERN
# OF BINARY DIGIT 

#!/bin/sh
coff=1
echo "enter size of your pattern"
read n
echo "The pyramidal binary pattern of size $n is:"
for((i=n; i>=1; i--))
do
   for((space=1; space<=n-i; space++))
   do
      echo -n " "
   done

   for((j=1; j<=i; j++))
   do
      if (( (i+j)%2==0 ))
      then
          echo -n "1 "
      else
         echo -n "0 "
     fi
    done
   echo
done


OUT PUT

enter size of your pattern
7
The pyramidal binary pattern of size 7 is:
1 0 1 0 1 0 1 
 0 1 0 1 0 1 
  1 0 1 0 1 
   0 1 0 1 
    1 0 1 
     0 1 
      1
