Dear BBEdit Folks,
I'm trying to clean off a backup drive with around 250 GB of data on it. I'd
like to save just one copy of any unique file, and hoping not to have to go
through the whole thing using Get Info's. (I think I'd prefer to lose the data
to doing that.)
I do have Compare Folders and opened it for the first time tonight; it didn't
seem to help, to the extent that I stayed with it. (At least for several
seconds....) I expect Omni Disk Sweeper might help when it comes to choosing
which folders with the same names do contain some differences, but I believe
that _most_ folders will fall into that category; I'm looking for something
faster. (I've used a backup program, ChronoSynch, that puts older versions into
archives. Mostly a good thing, until the cleaning time rolls around. And I've
created multiple sets and redone organizations, and well, I need to get better
organized, I think.)
How about GREP, I thought. But I don't know GREP at all.
Maybe someone there would be able to write a GREP expression for what I'm
looking for?
A. Search in: (Two hard drives, but they are partitioned. I don't care about
the second partition of the main drive but both of the backup's drive
partitioning matters.) The three items: 1. Howdy, 2. Seagate Disk One, and 3.
Seagate Disk Two. Howdy is the main drive's main partition.
B. Look for: all files with the characteristics
C. Such that they:
1. Are not housed within the /System or /Library file.
2. Are not housed within any directory beginning with "..".
3. Are not named beginning with "..".
4. Are unique.
I don't know GREP, but it seems to me that the first three are doable. I'm
wondering about #4. But without #4, I can't imagine how I could use GREP to
help with this *chore*. In the haste to dump large deep folders, I don't want
to accidentally delete the only copy I have of something; been there, done
that. (Gosh, I hate to clean out things!)
I'm thinking that between BBEdit's search, the Finder's search, and Spotlight,
maybe some scriptable comparison of results would work.
Assuming this isn't workable or practical, does anyone have any other
cleaning-out advice?
Thanks for any ideas,
Mary
