@farhad63,  
The issue is that your command is separated onto multiple lines. Put your entire command on a single line like to prevent this issue from occurring.

Alternatively, put a backslash character (`\`) at the end of each line to let the computer know that your command continues onto the next line. You will note this is what is done in the QIIME 2 documentation — breaking up the command onto multiple lines makes it easier to read in the tutorial, but requires the backslashes to the computer does not think each line is a separate command!

Good luck.
