This one has been bugging me for a while now.
It seems to just print out the contents of the files
passed in, after spliting them up and putting them
together again in a slightly odder way.
What is it for?
Comment on RE: ./whatever /etc/shadow /etc/passwd master.passwd.in
It is for merging the contents of /etc/passwd and /etc/shadow
on a system with shadow passwords (like Solaris). It inserts
the encrypted password from /etc/shadow into its proper place
and prints the result.
It could be useful for generating a full password file that you
could use with Crack, for example.
I'm not sure why the title has the "master.passwd.in" as a
third argument. I don't see how that gets used.
