I just rsync-ed 2,000,000 files (3TB) from one RAID to another.
I want to make sure my data is intact.
rsync -c
takes a really long time.
diff
doesn't show me what it's doing.
Is there an alternative that's (a) faster, and (b) will show me progress while it's comparing?
(I'm on Mac, and brew search diff
gives me apgdiff colordiff diffstat diffutils fmdiff libxdiff open-vcdiff podiff rfcdiff vbindiff
bsdiff diffpdf diffuse dwdiff kdiff3 ndiff perceptualdiff rdiff-backup tkdiff wdiff
... would one of these do the job?)
