will prompt for your password and imports your ether presale account. |

It can be used non-interactively with the --password option taking a |
||||
passwordfile as argument containing the wallet password in plaintext. |

accountCommand = cli.Command{ |

Action: accountList, |

Name: "account", |

Usage: "manage accounts", |
||||
Description: ` |
||||
|
||||
Manage accounts lets you create new accounts, list all existing accounts, |
||||
import a private key into a new account. |
||||
|
||||
' help' shows a list of subcommands or help for one subcommand. |
||||
|
||||
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>/keys. |
||||
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. |
||||
|
||||
In order to use your account to send transactions, you need to unlock them using |
||||
the '--unlock' option. The argument is a space separated list of addresses or |
||||
indexes. If used non-interactively with a passwordfile, the file should contain |
||||
the respective passwords one per line. If you unlock n accounts and the password |
||||
file contains less than n entries, then the last password is meant to apply to |
||||
all remaining accounts. |
||||
|
||||
And finally. DO NOT FORGET YOUR PASSWORD. |

{ |
||||
Action: accountCreate, |
||||
Name: "new", |
||||
Usage: "create a new account", |
||||
Description: ` |
||||
|
||||
ethereum account new |
||||
|
||||
Creates a new account. Prints the address. |
||||
|
||||
The account is saved in encrypted format, you are prompted for a passphrase. |
||||
|
||||
You must remember this passphrase to unlock your account in the future. |
||||
|
||||
For non-interactive use the passphrase can be specified with the --password flag: |
||||
|
||||
ethereum --password <passwordfile> account new |
||||
|
||||
Note, this is meant to be used for testing only, it is a bad idea to save your |

password to file or expose in any other way. |

Action: accountUpdate, |

Name: "update", |

Usage: "update an existing account", |
||||
Description: ` |
||||
|
||||
ethereum account update <address> |
||||
|
||||
Update an existing account. |
||||
|
||||
The account is saved in the newest version in encrypted format, you are prompted |
||||
for a passphrase to unlock the account and another to save the updated file. |
||||
|
||||
This same command can therefore be used to migrate an account of a deprecated |
||||
format to the newest format or change the password for an account. |
||||
|
||||
For non-interactive use the passphrase can be specified with the --password flag: |
||||
|
||||
ethereum --password <passwordfile> account update <address> |
||||
|
||||
Since only one password can be given, only format update can be performed, |
||||
changing your password is only possible interactively. |
||||
`, |

}, |
||||
{ |
||||
Action: accountImport, |

Name: "import", |
||||
Usage: "import a private key into a new account", |
||||
Description: ` |
||||
|
||||
ethereum account import <keyfile> |
||||
|
||||
Imports an unencrypted private key from <keyfile> and creates a new account. |
||||
Prints the address. |
||||
|
||||
The keyfile is assumed to contain an unencrypted private key in hexadecimal format. |
||||
|
||||
The account is saved in encrypted format, you are prompted for a passphrase. |
||||
|
||||
You must remember this passphrase to unlock your account in the future. |
||||
|
||||
For non-interactive use the passphrase can be specified with the -password flag: |
||||
|
||||
ethereum --password <passwordfile> account import <keyfile> |
||||
|
||||
Note: |
||||
As you can directly copy your encrypted accounts to another ethereum instance, |
||||
this import mechanism is not needed when you transfer an account between |
||||
nodes. |
