The part... -d' ' -f1 set the delimiter to the first
field.. per my unix1 class just a couple hours ago!
The space between the two ' ' sets the delimiter to
the space bar or white space in the output of $line
(if I understood Gerald, my instructor correctly.

Excerpt from the 'class' Here, we needed the
':' or colon delimiter, but you need the ' ' white
space delimiter

$ cut -f1 -d":" /etc/passwd | and on to another stdin

      The 'cut' command prints the values of field
      one found in the /etc/passwd file having colon
      delimited fields. 

He wrote one in the class as an example and used the
white space delimiter.

Hope that explains that/helped!!!
