mkdir command not found in bash script

Question

I don't know why I get error while running this simple script:

#!/bin/bash

read -p "Please enter directory name: " DIR
read -p "Please enter the path: " PATH
mkdir -p "$PATH/$DIR"

line 7: mkdir: command not found

Answer 1

Don't use the variable PATH. This variable contains a list of directories to search for executable programs. Since you're replacing it, the script can no longer find the mkdir program.

In general, avoid using variables that are all uppercase, these are often used as parameters for the shell or other programs.
