xargs-friendly repoutil commands?

[Jim Zajkowski]

I end up having to write this kind of thing a lot:

./repoutil --products | grep -v testing | grep -v Deprec | awk '{print $1}' | xargs -I % ./repoutil --add-product % testing

which runs slowly because (this) version of xargs doesn't want to expand more than one argument in place. Could a future repoutil update take arguments such that the "list" part is at the end, rather than in the middle?

Maybe a reasonable workaround would be something like "repoutil --with-branch testing --add 012-3456 034-1234 ..." If I were to submit a patch that added that, would that be acceptable?

I'm curious why you have to buik-add a lot of products to a branch "a lot".

I've been running Reposado for almost a year now. Apart from the initial setup, I find I rarely add more than a handful of updates to a branch at any one time.

Would people expect to be able to do this, though?

repoutil --with-branch testing --add-product foo bar --remove-product ipsum lorum?

I use that command-line construction because I don't like to copy/paste or retype the product numbers, and we're often not super fast about updating our repos, so when we do the updates there tend to be a lot. For example, for classrooms we don't alter the repo until we're forced to by a hardware changeover.

Either way, the "list part at the end" is a common unixy thing.

As to the other construct, I suppose someone could expect to do that, but I'm a bit surprised you can add and remove at the same time as it is.

"I'm a bit surprised you can add and remove at the same time as it is"

You currently can't, or at least, it's not properly supported.

Interesting, the code from github seems to (it runs twice, once for the adds, the again for the removes, in whatever argument order).

[Greg Neagle]

That scares me. Not convinced it will always do the right thing.

repoutil --remove-product xxx-yyyy testing --add-product www-zzzz production

Might do the right thing, but:

repoutil --remove-product xxx-yyyy www-zzzz testing --add-product aaa-bbbb production

Might not. I should review the code.

In any event, what about the --with-branch (or more accurately any way to put the package list on the end, rather than the middle) idea?

[Greg Neagle]

I'm fine with that if it can be implemented without breaking the current syntax. (not that I think the current syntax is the best, but now that Reposado is incorporated in other projects like JAMF's NetSUS, backwards compatibility is important).

As I wrote in another post, you can use awk inside backticks, which expands the entire list:

repoutil --add-product `repoutil --products | grep -v testing | grep - i -v deprecated |awk '{printf "%s ",$1}'` testing

This processes much faster
