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.

Gerry
