searching archive with "invalid context" gets to "bug#8231: Bug in the linux command: tail"
I read the exchanges from 2011 and see where it went, but gripe that now I have to type extra characters to invoke it.
Perhaps I should fear that "head" will eventually be "broken" also.
Attempting to use tail to get some number of lines other than default 10 on more than one file returns with error message "tail: option used in invalid context -- 2" or whatever N was used as arg.
head -N works fine

I did check the FAQ, and tried the bug-mailing archive ( see <oops> above ). I think that the difference between "head" and "tail" operation with "-N" usage points to a bug in tail.
