This was first reported in PTL-14841 and was then moved to PTL-15214 as part of a combined course-wide bug report. It is now being moved to its own Jira issue here. 

Example, `egrep -e "NAME|nova"` - First, I've seen this go back and forth from this to `grep -e NAME -e nova`.  I prefer the latter-use `-e NAME -e nova` because it is easier to understand as a beginner (otherwise you have to understand `egrep`, ``, and `|`).  Pick one method and mix all the ways we show it in the course. Second, there is no reason in this particular command to grep for NAME at all.  There is no header to look for, so remove the NAME part anyway.  Just `| grep nova`.

TODO: Decide whether grep/egrep usage will be standardized throughout the course. Edit all occurrences according to whatever is decided upon.

AFFECTED SECTIONS: Any lecture, GE, or Lab with a grep that is not in line with the agreed-upon standard usage. See search results at CL0002L, CL0003L, CL0005L, CL0006L, CL0007L, CL0008L, CL0010L
