There is no difference between echo $var and echo "$var".

However for other commands such as ls (list files) there could be a big difference.

Try this in your terminal:

$ touch "File A"

$ var="File A"

$ ls $var
ls: cannot access 'File': No such file or directory
ls: cannot access 'A': No such file or directory

$ ls "$var"
File A

The double quotes " tells Linux to treat everything in between as a single entity. Without the double quotes everything inside is treated as separate entities delineated by spaces.

So in the first example $var is two different things β€œFile” and β€œA”.

In the second example "$var" is one thing "File A".

The echo command automatically processes a single word or multiple words until the end of the line as one thing. Many other commands expect one or many things.
