[note: this was originally entitled "Rebuilding all reverse dependencies…", which was obviously incorrect. it was supposed to be "Reinstalling…"]
This post is mainly a reminder for myself in case the situation ever comes up again but, of course, it could always prove useful for someone else.
Recently, updates to
libtiff in Arch Linux required a rebuild of
all packages that depend on them, thus they all needed to be
re-installed manually. I knew there must be a more efficient way to do
this than to search the package listing on the Arch website to find all the
packages that depend on these two and then to manually check which ones of those I
have installed (this is what I started doing at first).
So, that’s when I put together this:
pacman -S `cat <(pactree -lrud1 libpng) <(pactree -lrud1 libtiff) | sort | uniq`
pactree -lrud1 lists all of the reverse dependencies of package to a depth
of one (so only the ones that directly depend on it). If you have to do this for
multiple packages, you can
cat together their output. Then you just sort the list
and get rid of duplicates with
