Hi, I'm fairly new to SF and have used the site mostly to get answers for my questions and provide answers to questions I know (read: the basic point of the site).
I recently posted an answer on this question: In tail -f, how do I filter out stuff that has certain keywords?
I answered at approximately the same time as another poster (he used egrep, and I used grep -E) and I will admit his came in first. I left mine because:
a) I was ignorant of the fact that egrep is just a symlink of 'grep -E' (hell, didn't even know egrep existed, tbh)
b) given A, I didn't realize mine was a duplicate answer.
My question is, from the perspective of helping the site (not my rep, since that's unimportant) do I just delete the answer and add a comment to his answer just because it came in first, regardless that it seems to be the popular choice?
/bin/egrepbeing a link to
/bin/grepis distro dependent. On CentOS 5 it's a link on Ubuntu 9 & 10 it's separate binaries.
