installation download its release and add binary to PATH env variable

usage amber run main.ab to simply run it

amber build main.ab main.sh to convert it into bash script ./main.sh

example

// importing inbuilt methods for array and text variables
import { split, slice } from "std/text"

const reduceFactor = 10

// this main function allows using arguments
main(args){

    echo(args[1])

    // accepting first argument  as folder. index 0 is just main.ab or bash
    const folder = args[1]


    // using commands and getting its output into text variable named 'res'
    let filesSortedByTimeStr = $ ls -t "{folder}" $ failed {echo(-1)}

    // converting string to array with demiliter
    let filesSortedByTimeArray = split(filesSortedByTimeStr, "\n")

    let abFilesSortedByTimeArray = []
    for index,file in filesSortedByTimeArray{

        if slice(file, -4) == ".fos" {
        // add elements into array
            abFilesSortedByTimeArray+=[file]

        }
    }

    const bufferFolder = "{folder}/tobedeleted"
    $ mkdir -p "{bufferFolder}" $ failed {echo("couldnt created tobedeleted folder")}
    for index,file in abFilesSortedByTimeArray{
        if index % reduceFactor != 0{
            $ mv "{folder}/{file}" "{bufferFolder}/" $ failed {}
        }
    }

    let res = abFilesSortedByTimeArray
    $ echo {res} > output.txt $ failed{}
}
