Recursive replace input value with process environment values in console

Typically it’s good to change a part of the worth of an setting variable to a different variable

I made a utility for such a substitute

Instance of utilization

Create env file
instance.env

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

Load file to present setting

export $(cat ./instance.env)

We derive the variable VAR1 within the typical approach

echo $VAR1

Outcome

var1${VAR2}

And now we’ll show the variable by way of the utility

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

Outcome

var1var2VAR3$NO_REPLACE
