How do we separate variables from letters in shell scripting?

Question

I tried printing \"Dogs are the best.\" with this bash script.

#!/bin/bash

ANIMAL=\"Dog\"
echo \"$ANIMALs are the best.\"
exit 

However, I

Answer 1

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"

I wouldn't use the quotes one most of the time. I don't find it readable, but it's good to be aware of.

Answer 2

Move your variable outside the quotes in echo :

#!/bin/bash

ANIMAL="Dog"
echo $ANIMAL"s are the best."
exit 

OR :

#!/bin/bash

ANIMAL="Dog"
echo "${ANIMAL}s are the best."
exit 

Both worked for me

Answer 3

Just surround the variable's name with curly braces.

#!/bin/bash

ANIMAL="Dog"
echo "${ANIMAL}s are the best."
exit 

Answer 4

Useless quotation, useless exit. A finished script needs no help to exit but the exit will bite you when sourcing that script.

ANIMAL=Dog
echo ${ANIMAL}s are the best.

Answer 5

#!/bin/bash


ANIMAL="Dog"
echo "{$ANIMAL}s are the best."
exit 

The answer is no longer unique, but correct...
