Building a simple command to traverse X steps toward the root-CodePudding

In windows, I had a batch simple script in my path that I could type "up 3" and it would call "cd .." 3 times.

"up.bat"

@echo off                         
if (%1)==() (                     
    cd ..                         
) else (                          
    for /L %%i in (1,1,%1) do (   
        cd ..                     
    )                             
)

How do I do the same in linux/bash scripting? The below doesn't lead to the directory changing

#!/bin/bash
for i in $(eval echo {1..$1})
do
   cd ..
done

Duplicate of the below, which includes both how to enact on non subshell and also how to make it a raw command

#!/usr/bin/env bash

for (( i=0; i<$1; i   ))
