Any way to get join to include the non-matching line ???


Need guidance if I should totally abandon join and use something else instead. I found several other options when searching for merge files in

Below are the test files to join:

$ head -1000 a.txt b.txt c.txt
==> a.txt <==

==> b.txt <==

==> c.txt <==

$ join -t"|" -j1 a.txt b.txt



Is there no way to get the E row from a.txt

$ join -t"|" -j1 a.txt c.txt

. Is there no way to get the B row from a.txt printed?
