Recursive replace input value with process environment values in console

Often you need to change part of the value of an environment variable to another variable

I made a utility for such a replacement

Example of usage

Create env file
example.env

VAR1=var1${VAR2}
VAR2=var2$var3
var3=VAR3$NO_REPLACE

Load file to current environment

export $(cat ./example.env)

We derive the variable VAR1 in the usual way

echo $VAR1

Result

var1${VAR2}

And now we will display the variable through the utility

echo $(npx -y rucken env-replacer $VAR1)

Result

var1var2VAR3$NO_REPLACE
