Re: matching an array

Is it going to match a specific column in the second file?
Does row #1 in file1 have to match row #1 in file2? What if row1 doesn't, but all other rows do?
Do you need to preserve the line for matches in file2? What I mean is if lines 1, 3, & 5 match, do you just have to say that or do you have to display the whole line for whom a column matched?

You might know what you're trying to do, but you're not explaining it very well. The more detail, the better the help.

just need to compare against column two in file2. Then print the whole line if column 2 mtaches file1.	[reply]

So, can line9 in file1 match the value on line3 in file2? What happens if the number of lines are different?

yes, the order is not important, anything can match at any point. The number of lines will not be equal, all i need is to find the lines in file 2 which bear reference to those in file1.	[reply]
