Re: Using one file to edit a second file.

Morning fellas, 

Thanks for the great feedback. 

Maybe I should have given a little more info or the more realistic issue. 

file1 is actually  a list of know exceptions. The format is given below and is tab delimited but I can squash to a single space ... 

icmp snmp ssh   
N       N       N       hostname              10.10.10.10

I then have file2, a "seedfile", Im basically trying to remove the know exceptions from the seed file. Its format is 

10.101.101.12 hostname Router (some other variable data)

I would normally use grep -vf for this operation. But the results arent as expected. I know this because I put both files into Excel and created formulas to basically do the same thing to double check my rookie bash script. The "numbers" are off by a thousand, that is the results of grep -vf is not inline with the spreadsheet results (sure about the spreadsheet results).

Both files number in the thousands of lines. 

I need to remove the exceptions from the seed and move on to other operations. 

At any rate, thanks for the help. I suppose Ill setup an if statement to get the desired results. ...that just seems spaghetti-ish .. know ?

Thank you again
Have a great day !!
