Is my wallet in rescan phase? No wat to check it via bitcoin-cli ?

Hello,
I'm trying to determine if my wallet on Bitcoin Core is rescanning for txs.
I would like to do a shell script to do this
Anyone has a way to do this via bitcoin-cli? It seems that there is no way but maybe there's something I'm missing.
Thanks in advice for help or suggestions.

Bitcoin Unlimited how to delete unconfirmed wallet transactions without rescan

So due to a mistake on my part while splitting my BCH and BTC, all my backups of my BCH wallet.dat file have unconfirmed transactions that are on the BTC blockchain. I downloaded the BCH blockchain using Bitcoin Unlimited in prune mode because storage is tight. I assumed that when it got past the BTC transactions it would simply delete them (they're the wrong transaction format and not in any block) but it hasn't.
All the methods of deleting transactions from wallets rely on using -zapwallettxes and -rescan, which I would rather not do (it took quite a while to download the blockchain to begin with).
Is there any way to delete those transactions from the wallet file without a rescan?
Note - the blockchain still has 10 days left to download, but the transactions are older than that.

Bitcoin core rescanning takes about 25 minutes

I love the idea of not running a SPV wallet and the only way to do that (that I know of) is via Bitcoin Core.
I like to use Bitcoin core to watch addresses but have always avoided running a rescan because it can take so long.
Today I bit (pun?) the bullet and imported a watch address that had old transactions.
Whilst rescanning the application is unresponsive with a small "Rescanning" dialog and a progress bar. After a few minutes the progress bar moved, and moved again. My mind was at ease and stopped worrying that my computer needed to crunch the blockchain for the rest of the day.
All done within 25 minutes.
Computer: Current model MacBook Pro.

So I just opened my bread wallet and had to make a new passcode and use my paper key to get the wallet. My wallet loaded at $0 which I know is not true. How do I get my balance back? I saw something about rescanning on another bitcoin post. How would I do that?

Could someone help me out? I downloaded Bitcoin ABC, synced with the blockchain, and rescanned my backed-up wallet. Why is my balance still zero?

After I rescanned with my wallet, I see all my transaction history, but beginning August 1st, they're grayed out (unconfirmed).
What's the best way for me to get my coins?

wallet.dat

On my computer, I have a couple of wallet.dat files that I "backed up" when I was running the bitcoin client. How can I find out which one is my actual wallet that has my bitcoin in it? (without installing the client and dealing with the blockchain download)
Details. I ran the bitcoin client off an external drive because the blockchain was huge and my SSD at the time was small. That external drive died. I made copies of the wallet.dat file a few times. I know some of the wallet files are blank but somewhere on my computer is my actual wallet.dat file that has my coin in it. last time I looked it was only a few hundred dollars worth. Nothing to make me rich but I want to use cashapp to manage it now and not sure how I can get my loot.
I apologize if this has been asked a thousand times but please help me out.

Bitcoin Core slow with Rescanning...

I'm using Bitcoin QT Core 0.15.0.1, and have the full blockchain on my computer.
After changing the wallet.dat I've been using to a different wallet.dat, I'm getting a "Rescanning... N%" window about the client supposedly rescanning something.
It takes more than 1 hour to finish this rescanning, and it's worrying, because I have at least 10 wallet.dat files, some might be the same as others, and it's been the 3rd wallet I tried that seemingly has the same transactions, and I'm not sure if all the wallets are really the same, or just Bitcoin Core is not actually reading the different wallet.dat file.
So any way I can speed up or eliminate this really slow "rescanning"?

Options For Better Rescan Speed Running Bitcoin Core on Raspberry Pi

Hey - Wasn't sure if this was a good place or /raspberry_pi but I run a full node on my Pi3 hooked up to a very old external HDD.
Everything runs great with a few other things bitcoin related, except when it gets an error (idk what it was) and it has to rescan/index through the blocks again. This literally takes a week+ just to scan through the blocks that are already there.
I am wondering where my bottleneck is, I'm assuming it's the old slow speeds of my external HD (I'm not exactly sure what they are actually). But since Pi3 is only USB2.0 what makes sense to upgrade, anybody running something similiar have any suggestions?
Wondering if a larger SD card is better or just a newer large flash drive? Or if it's all because of the Pi's limitations - Thanks guys
