I'm running F20 on gnome3 desktop, and I see some weird effect in the man command (entered in a gnome terminal) if using the "-P" command option:
man -P cat man >/dev/null
should use the cat command as pager. I get the expected effect, but one or more additional messages to stderr:
<standard input>:981: warning [p 7, 5.8i, div `3tbd1,0', 0.0i]: cannot adjust line <standard input>:990: warning [p 7, 5.8i, div `3tbd4,0', 0.0i]: cannot adjust line
Anybody knows what this means? No such message if the gnome terminal is wide enough.
It probably means what it says. You can format man pages with a variable number of characters per line, hence you might have "(setq Man-width 75)" in your ~/.emacs to get a reasonably formatted display rather than one with the lines being too long for comfortable reading.
Now say, you specify zero characters per line, and the software may suddenly have a hard time adjusting the lines.
In case lee's unclear: the output of "man" isn't going to your terminal any more, so it doesn't know how wide the output should be.
Hi Cameron,
Sounds reasonable.
Personally I would expect it to default to assuming an 80-column output and format for that. But it appears not.
I filed a BZ.
being that no one asked, i will.
why would someone send a man page to a null device?
to a printer, file, another terminal, yes. /dev/null, never.
because intent of 'man' is not to send output to /dev/null, why should it written to do so?
such is not intent of 'man', therefore, i would not consider doing such as a bug. other than person doing so. ;-)
