I have the following awk command, reading data from my local server(sun5) and remote server(sun8).Each doing the same command and displaying the differences into a diffs.txt file.
Code:
awk 'BEGIN {while ( getline < "sun5-printers.txt") {arr[$0]++ } } { if (!($0 in a
rr ) ) { print } }' sun8-printers.txt > diffs.txt
problem is that its not picking up all differences and displaying them.
here is an example:
sun5-printers.txt file
Code:
device for 5001a10: lpd://172.25.5.124:515
device for 5001a11: lpd://172.25.5.155:515
device for 5001a55: lpd://172.25.6.31:515
device for 5001a77: lpd://172.25.12.34:515
device for 5001a88: lpd://172.25.6.86:515
device for 5001a99: lpd://172.25.6.31:515
sun8-printers.txt file
Code:
device for 5001a11: lpd://172.25.5.155:515
device for 5001a44: lpd://172.25.6.31:515
device for 5001a77: lpd://172.25.12.34:515
device for 5001a88: lpd://172.25.6.86:515
device for 5001a99: lpd://172.25.6.31:515
NOTICE that its not picking up the 5001a55. Any advice on how to fix the awk command?????
diffs.txt file
Code:
device for 0601ps1: lpd://172.25.53.36:515
device for 0601ps2: lpd://172.25.53.30:515
device for 0606ge1: lpd://172.28.9.29:515
device for 5001a44: lpd://172.25.6.31:515
your script is to print those lines in sun8-printers.txt which is not there in sun5-printers.txt, and hence the line which you expected did not come out since its not there in sun8-printers.txt.
The expected functionality is too display, differences in both the remote server and the local server.
oh okay, how can i change the awk command , so that it will display differences in the sun5-printers.txt as well as sun8-printers.txt?

Would reversing the filenames..give me a different output?????
ok ran command and now i see the differences!
thanks a million

Why are duplicates being displayed, as i already know that they are due to the different IP addresses on the servers?

' sun5-printers.txt sun8-printers.txt > diffs.txt
this awk works but is displaying duplicates which is causing confusion with the rest of my shell script!
My shell script reads the differences from the diffs.txt file, deletes them and then recreates them.
BUT because of the duplicates its recreating them incorrectly...
any advise please????
here is the diffs.txt

I've been doing some research for the last three hours..keep on running into a brick wall.
Can someone please tell me how I can fix the awk command not to produce the duplicates, and only show the differences????

thanks franklin52
the names of the devices are the duplicates i am talking about. these duplicate names have different IP addresses.
Code:
device for 0601jc1: lpd://172.25.53.33:515
device for 0601jc1: lpd://172.25.9.104:515
the correct Ip is the 1st line, and the 2nd one needs to be changed.
Currently the script deletes the device fine but recreates it with the 2nd line..which is incorrect!
