concatenation of two strings
EX.NO:3.f CONCATENATION OF
TWOSTRINGS
Aim:
To write a shell program to concatenate two
strings.
Algorithm:
Step1: Enter into the vi editor and go to the
insert mode for entering the code
Step2: Read the first string.
Step3: Read the second string
Step4: Concatenate the two strings
Step5: Enter into the escape mode for the
execution of the result and verify the output
Programcode:
echo “Enter the first string”
readstr1
echo “Enter the second string”
readstr2
echo “The concatenated string is” $str1$str2
Sample
I/P:
Enter the first string: Hello
Enter the second string: World
Sample
O/P:
The concatenated string
is HelloWorld
Result:
Thus
the shell program to concatenate two strings is executed and output is verified
successfully.

EX.NO:3.g COMPARISON
OF TWOSTRINGS
Aim:
To write a shell program to compare the two
strings.
Algorithm:
Step1:
Enter into the vi editor and go to the insert mode for entering the code Step2:
Read the first string.
Step3: Read the second
string
Step4: Compare the two
strings using the if loop
Step5: If the condition satisfies then print
that two strings are equal else print two strings are not equal.
Step6: Enter into the
escape mode for the execution of the result and verify the output.
Programcode: ” echo “Enter first string” readstr1 echo “Enter second string” readstr2 if [
$str1 = $str2 ] then echo “The
two strings are equal else echo “The two strings are not equal” fi |
Sample I/P:1 Enter
first string: hai Enter
second string: hai Sample O/P:1 The two
strings are equal Sample I/P:2 Enter
first string: hai Enter
second string: cse Sample O/P:2 The two
strings are not equal |
Result:
Thus the shell program
to compare the two strings is executed and output is verified successfully.
