Pipe the "yum list available" output through less, and you'll see
what is happening. In general we don't recommend screen scrapping
yum
output, writing a yum script is often significantly easier (and
supported).
For what I _think_ you are trying to do above, you probably just
want
"yum list updates" or "yum check-update" output.
and if you feel you MUST use a script to do this: look at
repoquery from yum-utils.
-sv
Ok, through 'less' I can see that the output is being forced onto a
second line. But rather than do that, it would be better to just
push the output out by $COLUMNS and it would look exactly the same
but still be on the same line.
did you see what I just said?
yum is NOT intended to be screen scraped. Either write a python
script or use repoquery.
I get your point. But people do scrape these outputs for quick
scripts. If you put it on stdout people are going to scrape it pretty
much. Anyway, I'll look at making a python script.
Ok, I am looking at repoquery but some of the totals do not seem to
add up. For example:
repoquery -q --pkgnarrow=updates -a | wc -l
498
Now I would expect that when I do this:
for arch in i386 i586 i686 x86_64; do
Oops misquote : the line should have read: for arch in i386 i586 i686
x86_64 noarch; do
repoquery -q --pkgnarrow=updates --archlist=$arch | wc -l
done
that the totals for all the arches would equal the 'all' total. But
they don't. The arches totalled separately add up to more than 100
packages more than the 'all' total. How can that be?

Gerry
