Details

Currently, if one upgrade his system and if something went wrong at the next boot for example, it might come from one of the packages that have been installed.

If we don't remember what was the list of installed packages, well, the only way I thought about was to "pacman -Qi" but it displays too many informations and is not easy to parse.

It would be nice to be able to have a list of packages that have been installed after a given date. I first thought about doing a script with regexps but well, it would be more convenient to have it in pacman itself.
This task depends upon

Looking at pacman.log doesn't accomplish this? There are several such scripts, including `paclog-pkglist` from pacman-contrib, that will do this for you and have all the parsing, if you just copy your logfile and trim it at the appropriate place.

This is trivial with expac and some bash:

when=$(date -d yesterday +%s)
expac --timefmt '%s' '%l\t%n' | while read dt pkg; do
if (( dt > when )); then
printf '%s %s\n' "$dt" "$pkg"
fi
done

if you want to get into bash4.2, you can even get pretty printed dates using the %(%c)T token in the print format string.

You're right about logs, that's what they are for…

Seems like I made a stupid request… I'll think twice times more next time!
