Any GUI Linux directory comparison tools that work?

I tried KDIFF3, it crashes partway through comparison. I understand that v1.10 has a bug and crashes when a directory has symlinks in it, as my home folder does.

I tried KDIFF3 v1.12 via the abomination called Flatpak, but it also crashes partway through scanning.

I tried MELD, it just hangs there "scanning" but uses no CPU and is doing nothing...

Ideas?

@dancingtreefrog Would it be worthwhile in your case to print the directory structures to files and then compare the results? It's definitely not as good, but it could be more stable.

Including file sizes could be informative. You might also be able to include file hashes to represent the content… Depends on what you're trying to do though

@AcornSquashbuckler Well, CLI diff can give me a list of files that are ONLY in the second folder by feeding to grep and looking only for the pathnames referring to the external drive...Might be an option.
I’ve written some perl scripts to do that. If that sounds useful, hit me up and I’ll share a copy. @AcornSquashbuckler @dancingtreefrog
