There are three types of quotes
Quotes | Name | Meaning |
| " | Double Quotes | "Double Quotes" - Anything enclose in double quotes removed meaning of that characters (except \ and $). |
| ' | Single quotes | 'Single quotes' - Enclosed in single quotes remains unchanged. |
| ` | Back quote | `Back quote` - To execute command |
Example:
$ echo "Today is date"
Can't print message with today's date.
$ echo "Today is `date`".
It will print today's date as, Today is Tue Jan ....,Can you see that the `date` statement uses back quote?
