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

can you make your problem description clearer?

text="This is just a test string"
case "$text" in
    "This is"*) echo "match";;
esac

the above assume you want to match "This is" at exactly start of line.
