Manage accounts lets you create new accounts, list all existing accounts,

'account help' shows a list of subcommands or help for one subcommand.

non-interactive mode where passwords are supplied via a given password file.

Non-interactive mode is only meant for scripted use on test networks or known
|
|
safe environments.

Make sure you remember the password you gave when creating a new account (with
|
|
either new or import). Without it you are not able to unlock your account.

Note that exporting your key in unencrypted format is NOT supported.

Keys are stored under <DATADIR>/keys.

It is safe to transfer the entire directory or the individual keys therein

between ethereum nodes.

Make sure you backup your keys regularly.

The keyfile is assumed to contain an unencrypted private key in hexadecimal format.
