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.

-sv
