Determine if file is %BACKUP%

1311219 · 2007-09-22 10:22:10

Is there any way to know if a file will be overwritten when the package it belongs to is synced?
For now, the simplest solution I've found is to look at "/var/lib/pacman/local/<packagename>/files", but I would really appreciate if pacman could do this (like the way it can check for which package a file belongs to, and list what files belongs to a package etc...).

Thanks for any reply.

Oh, come on, anyone!

Just a "AFAIK, that is the only solution" reply would be enough...

In the common case, you can just do : pacman -Qii <package> and it'll show you the files in BACKUP for the current version of the package.

In the particular case where the file has just been added to the backup array of the new package, it won't show up in pacman -Qii (since this queries the old package), but the file still shouldn't be overwritten during the upgrade.

Interestingly, -Qii doesn't seem to be documented anywhere. It used to be in pacman -Qh. I'd have to check if that's a known issue.

OT: 1311219, impatience may work for you elsewhere, but it's not particularly appreciated here. If nobody answers your question, just wait, or ask somewhere else e.g. mailing list, IRC, etc.

Hmm, apparently there was indeed something in pacman 2, but apparently it wasn't explicit, and even confused an user :

But thinking about it, even though -Qii currently only adds the list of backup files, I guess it could be used for other additional informations in the future.

thanks, shining, that solved everything!

OT: tomk: I usually ignore that kind of replies, since I mostly agree, but I feel that I should clarify the reason for this doublepost: I have been waiting for a reply to the first question I asked on this forum (link) for a long time now (back in those days I was extremely afraid of making those kinds of mistakes, and didn't even know it was possible to delete posts myself, and asked if a mod could move the topic ). After that time, I started to realize that all questions on this forums won't be answered, so I find it acceptable if people do a revival post in order to bring a (usually quickly answered) question to an end. (note: I'm not trying to completely justifying the doublepost, just explaining why I did it (plus I was quite tired when deciding to post, after working on to much coding ))

I'm not using IRC so much, but I really appreciate your recommendation of it, and will look into using that for simpler questions
