Write a Bash script that implements a function called power that takes two numbers as arguments and prints the result of raising the first number to the power of the second number. Code: #!/bin/bash # Define the power function power() { local base=$1 local exponent=$2 local result=$(...
In Bash scripting, dealing with numbers and specifically rounding them to a certain number of decimal places is a common task. For example, given a number like 3.14159, the goal is to round it to two decimal places, resulting in 3.14. This article explores various methods to achieve this in...
It returns the greater of the two numbers. User Input: The script prompts the user to enter two numbers. It validates that the inputs are valid numbers (allowing for negative numbers and decimal points). Maximum calculation and output: The script calls the "maximum()" function with the user...
It's important to note that bash is limited to performing integer arithmetic, unlike ksh93, zsh or yash which can handle floating point numbers. If your calculations involve decimals, then you may need to use other tools. One such tool isbc. $ b=3.14 $ echo "$(($b + 1))" bash: ...
kubernetes_secrets_compare_gcp_secret_manager.sh - compares each Kubernetes secret to the corresponding secret in GCP Secret Manager. Useful to safety check GCP Secret Manager values align before enabling External Secrets to replace them kubernetes_secret_to_external_secret.sh - generates an External ...
You can pipe any mathematical string tobcwith the-lflag in order to use decimal numbers in your calculations. 5.1.1Summary Bash programs are executed in order from the first line in a file until the last line. Anything written after a pound sign (#) is a comment and is not executed by...

Based on this unique combination, I need to compare each field value between the two files and report the difference. Note: File in Directory A has values displayed upto 5 decimal places. But file in Directory B has some values displayed as scientific values, some whole numbers and some ...
