Regex match a string with spaces (use quotes?) in an if statement

Question

How would I do a regex match as shown below but with quotes around the (\"^This\") as in the real world \"This\" will be a string that can have spaces in it.

#!/         


        

Answer 1

You can use \ before spaces.

#!/bin/bash

text="This is just a test string"
if [[ "$text" =~ ^This\ is\ just ]]; then
  echo "matched"
else
  echo "not matched"
fi
