Shell Programming

Write UNIX Shell scripts to solve the following programming problems -

1) Write a shell script that calculates GCD (greatest common divisor) of two numbers.

• You may take the input numbers from either command line or using standard inputs.

• The program must check if the inputs are numbers.

2) Write a shell script to make a CLI based calculator, the program should behave as follows:

• The program must start with a clear screen, prompting to input two numbers.


• Once given, it must list 5 operations (Add, Sub, Mul, Div, and Mod).

• Based on the user’s choice, it should perform addition, subtraction, multiplication, division,

and modulus (manage any illegal operation e.g. 0/0).

• Once calculated, the result must be printed on a new line and the program must print “Press

any key to continue” on the next line.

• Pressing any key, the program must go back to the first step.

3) Write a shell script that takes a decimal number as input and prints its binary, octal, and hexadecimal equivalents.

• Check if the input is a number.

• You may use any inbuild unix tool to perform the conversion.

4) Write a script that takes two filenames and returns the one having more lines than the other.

• Filenames must be given with their relative paths.

• In case of a tie, the script must return both the filenames.

• In case the files are empty or do not exist, the program must print a custom error statement.

5) Write a shell script that creates a CSV file and records the number of packets sent and received by

a given network interface ordered by the timestamp.

• The interface name and the interval must be provided by the user using a command-line


• Please note, a CSV (Comma Seperated Value) file is a text file that stores a table. The

first line records the column names and the followig lines record individual rows. Each value

seperated by comma (See the example below)

name year marks

abc 2 86

xyz 1 45

pqr 2 66

• the CSV formation of the given table is,
