More with a percent more. I think.
| 
Dec 3 00:03 UTC 1993 |
I'm currently using the pager "more" for the bbs. Sometimes I see a
"more" prompt that tells what percent of the text has already been seen.
Is that pager available for use in a .cfonce file?

I think that's just more. When it's getting its input from a pipe, which I
think applies in this case, it can't tell how much input there's going to
be. When you use more on a regular file (possibly with some other conditions)
it knows how much more there is.
It's possible that you might define your picospan pager in such a way as to
get such a progress report. I'm not sure that it's possible, but if it *is*
one almost-certain consequence would be an appreciable delay when you start
to read something before anything is displayed. I suspect this would quickly
outweigh any possible gain from knowing how much more there is.

Good question and good answer. I've always wondered about this myself.

Thank you. I just read the man page - but it kind of stuck, because it made
sense regarding *why* (which the man page didn't address, but which seemed
obvious as soon as I wondered).

... and since the pager and the original command are running at the same time,
the pager can't tell what percent complete things are - new input may be added
at any time, up until the command terminates.

OK, related question: I'm using more as my pager for the bbs too. Are
there other programs besides more that would make good pagers?

In "unix", "less" is more than "more".

That's not democratic or cooperative. In democracies and cooperatives, you
are required to endure twits.

The version of twit I use is in /u/jon/bin/twit. The documentation
is somewhere in one of those directories.
Re 10 - Yes, but I'm not a democracty.

Here's what I have.. do a define pager /u/yourusername/mymore after copying
the file /u/jared/jmore to /u/yourusername/mymore
This will show you your precent more.

There's only one problem with it.. it goes
:::::::::::::::
/tmp/mre.#####
:::::::::::::::
at the beginning of it all.. that's the only problem there is with it.
And it asks you to tell it to start. I dunno if there is a way
around that.

At least with a script you can look at it, make sure it's innocent, and
copy it to your own dir & use it, knowing no one except root people can
change it while you're not looking. (And changes could be innocent and
still produce disaster, if you're depending on a script's behavior to
remain the same.) It's an even worse idea to depend on a compiled program
from someone else's dir, since you can't check what it does.

Re: 20, isn't this why some Unix books say that putting '.' as the
first item in a path statement is a bad idea?

Related. Imagine this scenario: You change to /tmp (say), where lots of
people have write access. You run ls -l. Some bozo has put in /tmp a
script called ls which does rm -r $HOME. If your current dir is in your
path ahead of /bin or any other official ls, you wind up deleting your
entire directory, & everything under it. (bozo couldn't do it directly,
since he didn't have access - but *you* can.) *Very* bad, since we don't
have any way to do backups here right now.
