This in principle agrees with my original analysis.
(I'll also note that findstrip doesn't work:
$ find . -xdev -type f \! \( -name '*.o' -o -name '*.so.*' -o -name 'lib*'
-o -name '*.do' \) -print | xargs file | awk -F: '$2 ~ /not .*strip/ { print $1
}'
xargs: unmatched single quote; by default quotes are special to xargs unless
you use the -0 option
and findcore finds files matching "(vg)?core(.[1-9]+)?"
which is not what coredumps are called in the general case,
so the utility of that utility is questionable as an addition.)I've written /a/ finddup like every three months for the past few years, and every time I'm annoyed util-linux hardlink(1) doesn't have a "just give me the duplicate files" mode, so I just wrote it: https://lore.kernel.org/util-linux/5acde6a911f086ab8d2314c5b76eb76075140941.1730139540.git.nabijaczlew...@nabijaczleweli.xyz/t/#u hardlink(1) is a widely-used canonical implementation with ongoing maintenance (naturally, it's in util-linux). > What do you consider the best way of action here? If the patchset lands in util-linux, that renders the entire package obsolescent. I'd say 1. fix the bit where finddup reads the whole file into memory (this is in git already) 2. don't add more binaries or whatever, don't shim out zum like it is in git 3. declare the package obsolescent, > The whole thing should be explained in NEWS.Debian. since there's a non-insignificant popcon here 4. remove it from forky This code is best left in 1996 where it came from.
