Shell Scripting use of variable in string

 With braces: echo "${ANIMAL}s are the best."

With quotes: echo "$ANIMAL"'s are the best.'

With printf: printf '%ss are the best.\n' "$ANIMAL"







The best way is to use ${variable} in string because when you need multiple variable in a string, its easier
