7/13    Is mail working?  Neither incoming nor outgoing mail seems to be
        working.  I've received no email (not even spam) since last night.
        And outgoing mail doesn't seem to be working (or at least it's
        delayed more than a couple minutes).
                I think there are about 50K messages in the queue... -ax

10/6    What's the easiest way to get the ip from the env var
        SSH_CLIENT="10.10.10.10 1212 22" in bash? I want to use it to
        set the DISPLAY env var.

           others).

8/19    I have files full of  s that I NEED to squash, nothing I've tried
        works though. (shy of going in with an editor and deleting each one).
        They all exist at the beginning of a line and are followed by another
        strange charcter "»" if that helps.  OS = Linux.
        \_ sed is your friend.

4/15    Unix Wizards, how would I sort a list like this in numerical order?

1/4     Hello UNIX command line gurus, let's say I have a file called
        filenames.log that contains file names, like /usr/bin/hello,
        /media/dvd/wayne's world, /media/music/my music!.mpg. I'd like
        to do something like:
        % cat filenames.log | xargs tar rvf /backup/today.tar
        However, I can't do that because I need to escape characters

1/29    sed help.  How do I take a file, and replace all newlines/returns with
        spaces, so that a multi-line file becomes one long line?
        ideally, something like sed "s/$\N/ /g", but this doesn't work.
