If a file does not exist both > and >> operators will create the file.
If a file does exist > operator will overwrite the contents of that file.
If a file does exist >> operator will append to the end of that file.
Example of use of both operators:
"echo blabla > testfile"
This will create a file called "testfile" with the text "blabla" in its content.
If there already was a file called "testfile" it will replace its content with the text "blabla"
and
"echo blabla >> testfile"
This will create a file called "testfile" with the text "blabla" in its content.
If there already was a file called "testfile" it will add the text "blabla" at the end of the files content.
