I tried to create a text file in a bash script.The echo command spans multiple lines and has some double quotes .#!/bin/bash echo blabla bla bla bla blabla bla bla  bla bla blaand so on and so onbla blablu bla  bla bla bla bla bla > /root/bin/blaThere are many double quotes  in echo command that is undesirable.And I did #!/bin/bash echo 'blabla bla bla bla blabla bla bla  bla bla blaand so on and so onbla blablu bla  bla bla bla bla bla' > /root/bin/blaI wondered if there are any difference between double quote  and single quote 'Which one has higher priority? Is it just the fact that they are visually different?
What is the difference between ' and ?
