they work with fedora (linux) ?
They all seem to have Linux versions (or the source code) available... given Electrum is Python=based, as long as you have Python installed and running, it *should* work OK... but I don't use fedora, so I can't confirm 100%. I've used them all on Ubuntu VM OK.
bither +bitpie , is there a way to bulk accept and get the forkcoins there, cause they want you to manually confirm every single private key with password... takes forever...
Not that I'm aware of. As your coins came from Electrum, you can't just import the seed as Electrum seeds are not BIP39 compatible and, as far as I'm aware, the only wallets that support Electrum seeds are Electrum and Electrum-based forks.
Other options include using the "Core" wallets for each fork as they generally allow for bulk importing... but then you'd need to sync full blockchains for each fork.
