sed *n l pathname
The latter also has the advantage that its output is
unambiguous, whereas the output of historical cat
*etv is not.
But mind you, in preparation of this email i found a bug in
Busybox sed(1) which simply echoes nothing for the above.
I assume that * is a typo for - . If so, sed did just what
-n tells it to--no printing except as called for by p or P.
And speaking of sed anticipating other tools, the inclusion
of "head" in v7 as a complement to "tail" was a close call
because head is subsumed by sed q.
