I wish I could go into lots of detail here, but I can't.
The difference between a linux password file and a freebsd one is that
all the same information is there, but one has more fields than the
other does.
I've converted password files between various unices using sed and awk
scripts. Here's the quickest, vaguest sed/awk lesson you'll ever get:
orpheus:vi3g/BUV6Y05.:500:100:Jeffrey Dunitz:/home/orpheus:/bin/bash
orpheus:mz/.Rcl79oNnS:500:100::0:0:Jeffrey Dunitz:/home/orpheus:/bin/bash
So there's two example password entries, one from a standard unix password
file and one from a FreeBSD master.passwd. Note that freebsd has some
extra :0:0: stuff.
Also notice that the fields are separated by : characters.
Also note bigtime that those encrypted passwords are made up and just look
like actual passwords. I'm not stupid enough to mail out my actual password
file entries so that you all can try to crack them. :)
Anyway...
You can use awk to spit out fields and arbitrary data:
cat /etc/passwd | awk -F: '{print $1":"$2}'
just prints the first two fields with the colon. You have to quote the
colon like that, or it won't work right.
You can then figure out how to add in the extra ":0:0" stuff on your own.
Should be easy.
Note that there are some religious fanatics who would insist that the only
way to do this right is to use Perl. Other crazies will tell you that you
must use sed. I know how to do it with awk, and it took me about 45 seconds
to actually figure out how to do it. It would take me another 45 to actually
generate a working password file with the extra stuff in there. I don't know
if I could figure out how to make perl do that same thing. I'm not a perl
god. Your mileage may vary.
