Yup - that's my fault, and contrary to my intent - I was using the web interface, and it's too easy to just hit the reply button instead of "reply to all" - mea culpa. > On Thu, Sep 13, 2007 at 10:32:34AM -0700, Kurt Buff wrote: > > > On 9/13/07, Jerry McAllister <[EMAIL PROTECTED]> wrote: > > > On Thu, Sep 13, 2007 at 10:16:40AM -0700, Kurt Buff wrote: > > > > > > > I'm trying to do some text file manipulation, and it's driving me nuts. > > > > > > > > I've got a sorted file of SMTP addresses, and want to eliminate the > > > > lines that are the same up to a space character within the line. > > > > > > > > Example: > > > > > > > > [EMAIL PROTECTED] NO > > > > [EMAIL PROTECTED] OK > > > > > > > > The above lines *both* need to be eliminated from output - I don't > > > > want the first or second of them, I want them both gone. > > > > > > > > I've looked at sort and uniq, and I've googled a fair bit but can't > > > > seem to find anything that would do this. > > > > > > Seems like this is right up sort's alley. > > > Is the first string always separated from the rest by white space > > > or does your first string sometimes include white space. > > > > > > ////jerry > > > > The only space is the one separating the SMTP address from the OK or NO. > > Then you should be able to tell it to sort on the first token in > the string with white space as a separator and to eliminate > duplicates.

Tried that, and it doesn't work the way I expect, or else I'm doing it wrong, which is definitely possible. My first difficulty is that I can't figure out how to specify the space as the field delimiter, assuming that -t is the correct parameter for that. I've tried specifying '@' for -t, but that doesn't work either. Next, my suspicion is that the -u parameter will simply output the first line of a set of non-unique lines, which is what it does normally - it doesn't seem to eliminate all non-unique lines, it just makes the first line the unique one. Am I making sense?
