You could try something like:
sort /etc/passwd > passwd.in
sort /etc/shadow > shadow.in
join -t : -j 1 -o 0,2.2,1.3,1.4,1.5,1.6,1.7 \
passwd.in shadow.in > merged
This does not preserve the subsequent fields of shadow(4), though. I
would be inclined to just keep a copy of the interesting lines from
"passwd" and "shadow" in separate files.
Cheers.
