I searched through the forums, and there are a couple threads that have a similar problem to mine, but they don't seem to exactly address my problem.
I'm running an HP-UX box, trying to create a little script that will compare the /etc/passwd file with another file I have created.
Each line in this file, let's call it /etc/myusers, has a pin that the user has chosen (not necessarily unique), then their userid, then the comments field from /etc/passwd. (basically their full name, phone number, all that jazz.
Here is an example:
Quote:
pin:userid:comments:
1234:pittb:"Brad Pitt,Los Angeles CA,123-123-1234":
9876:clooneyg:"George Clooney,Los Angeles CA,123-123-1234":
6548:dansont:"Ted Danson,Los Angeles CA,123-123-1234":
9685:owenc:"Clive Owen,Los Angeles CA,123-123-1234":
1652:simpsonh:"Homer Simpson,Los Angeles CA,123-123-1234":
I basically want to make sure that every account in my /etc/passwd file is also in this file. So all I want to do is go through each line in /etc/passwd, and search for each userid in this custom file. If the name DOESN'T exist in my custom file, I want to print it out (from /etc/passwd) to the screen, or a file, or whatever, so I can go through and add all the accounts to this file.
It should be fairly simple, I just can't quite figure it out.
I was thinking of just doing an awk on the /etc/passwd file and pulling out all the usernames to a file, and then doing a for loop through that file, or something like this:
Well, I'm not sure how to read that ouput from the diff command. I looked at the man page, but it still doesn't make much sense. I can see that it's listing all the users, and then every so often printing some weird numbers, I'm assuming are correlating to the lines or something.
What I need is a nice clean output of simply the lines in /etc/password that do not have a corresponding userid in /etc/myusers.
one good logic is to ...cut and have column 2nd then 1st on each line from passwd file and redirect the output to file lets say a1. Then do the same on other passwd file and save the file as a2. Sort both file one by one and redirect output to a1sorted and a2sorted. Now run "sdiff a1sorted a2sorted"
and it will show you where we have extra members or less members..
