DevOps BootCamp: Bash Functions

In this task you need to create some functions.

⚠️ Please, don't call your functions in ./functions.sh file. This would breake unit-tests. Create a new file and do source ./functions.sh there to test your functions.

Pow Task

Develop a pow() function that takes two arguments (a, b) and raises the first argument to the power of the second (a^b).

Check

pow 2 3 -> 8

pow 2 5 -> 32

Shortest string function

Develop the shortest() function, which can take an unlimited number of arguments(strings) and output the shortest argument.

Check

shortest "This" "is" "Bash" "Functions" "Task"

is

If there are more than two arguments, output each string on a new line. In an order they are passed to function.

shortest "Java" "Bash" "Python"

Java

Bash

Log function

Develop a print_log() function that takes a string as an argument and outputs the same string with the date at the beginning. In order for the automatic check to work, the string must be in this format: YEAR-MONTH-DAY HOUR:MINUTES

print_log "Hello World!" -> [2022-05-10 13:04] Hello World!

print_log "Hello Bash!" -> [2022-05-10 13:10] Hello Bash!
