What do you call these different quotes?

I got question about quote. There many few quote usin开发者_运维技巧g documentation:

• '
• `
• ‘
• ’
• "
• “
• ”

How to say or tell it in word?.

There few symbol quote not include in keyboard, (“, ‘, ’, ”), how could I using symbol without copy-paste from other document.

As programmer view, it really matter write quote to make different from one to another?

Yes, it definitely matters!

• ' single quote (aka apostrophe)
• ` backtick (aka grave)
• " double quote

The other ones (‘, ’, “, and ”) are simply known as "smart" or "curved" variants of their "straight" or "dumb" brethren (' and ").

Precisely how it matters depends on the programming language you're using.

More info here.

depending on the language the quotes matter. A simple example can be done in bash, where quotes are everything:

bash$: "I am `whoami`"
I am root
bash$: 'I am `whoami`'
I am `whoami`

In the case of bash ( and many other languages ), using single quotes, vs double quotes has serious implications. Check the language you're using for documentation on how each token is treated.
