Getting “command not found” error while comparing two strings in Bash

Question

My whole Script is currently this:

#!/bin/sh   
clear;   
blanko=\"\";   
# Dummy-Variablen
variable=Testvariable;   
if [[$variable == $blanko]];
then   
           


        

Answer 1

If your script runs on your local with /bin/bash but not on your container with sh, then consider adding bash to your container by apk add --no-cache bash.
