You can use a bash script to import multiple keys, first of all put all those keys on a text file and then you can run something like:

Code:

for a in $(cat keys.txt)
 do
  bitcoin-cli importprivkey $a
 done

By default, Bitcoin Core will rescan whole blockchain to find all transaction related to the imported private key. If OP insist use Bitcoin Core, i think skip scanning when import private key & perform scan after all private keys are imported is more efficient.

Code:

for a in $(cat keys.txt)
 do
  bitcoin-cli importprivkey $a "" false
 done

bitcoin-cli rescanblockchain

I have thousands of old bitcoin private keys. Is there a program to reveal the bitcoins address on this private keys?
Or is there a simple programming code to convert the private keys to bitcoin address?

You can use this script

Good luck

note that this code doesn't give you "addresses" (which is what OP is looking for), instead it gives you public keys and that only in uncompressed form which you have to first decide whether you want to use the compressed or uncompressed type then you have to hash them and do the address encoding (base58 or bech32) to get the respective addresses.

If the goal is to only get the address i think OP should take a look to this link about how to generate a bitcoin address step by step, if OP understands the theory about it he will be able to code his own script to get the addys of all those privatekeys.

That script is a good option, dooglus is one of the best coders on this community, but if you get the address you will have to verify their balance one by one, that's why the best option is to import those privatekeys on a bitcoin wallet, if you use bitcoin core the command to import a key is the next one:

Code:

importprivkey yourPrivateKeyInWalletImportFormat

You can use a bash script to import multiple keys, first of all put all those keys on a text file and then you can run something like:

Code:

for a in $(cat keys.txt)
 do
  bitcoin-cli importprivkey $a
 done
