Shell script to find factorial of a number

You can create a shell script to find the factorial of a number using a while loop. Here is an example: In this script, we prompt the user to enter a number and store it in the variable number . We then initialize two variables, factorial and counter , to 1 and the value of number , respectively. We use a while loop to iterate through the numbers from the value of number down to 1. In each iteration, we multiply the current value of factorial by the current value of counter , then decrement the value of counter by 1. At the end of the loop, we output the final value of factorial , which is the factorial of the number entered by the user. You can execute this script by making it executable by running chmod +x scriptname and then you can run ./scriptname. Make sure that you have bash installed in your system, otherwise, you have to use a different shell accordingly. This script uses a for loop to iterate from 1 to the given number, and calculates the factorial by multiplying the cur...

Difference between static ip and dynamic ip

An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. There are two main types of IP addresses: static and dynamic. A static IP address is a fixed IP address that is manually assigned to a device. Once a static IP address is assigned to a device, it does not change, regardless of whether the device is turned off or disconnected from the network. A dynamic IP address, on the other hand, is assigned to a device dynamically, typically by a DHCP (Dynamic Host Configuration Protocol) server. Dynamic IP addresses are assigned each time a device connects to a network, and they can change over time. Here are some differences between Static IP and dynamic IP Persistence: Static IP addresses are persistent and do not change, whereas dynamic IP addresses are assigned each time a device connects to a network and can change over time. Manual or Automatic Configuration: Static IP addre...
