It supports interactive mode, when you are prompted for password as well as

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>/keystore.

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

between ethereum nodes by simply copying.

Make sure you backup your keys regularly.`,
