how about

ethereum account export <address> <path>
and
ethereum account import <keyfilepath>
i would not encourage people to have their private keys in console histories (esp. if we allow unencrypted format).

Importing from command line is important for system-testing. Maybe both should be supported.

[zelig]

I think you can always get round it ;)

ethereum account import <(echo mynotsosecrettestkey)

[obscuren]

I've never seen the importance of supplying a file when you can do cat file (apperantly iPhones haven't got backticks on their keyboard)

[tgerring]

Tap and hold the single quote key--a popover menu should appear with the backpack symbol ;)

[zelig]

@obscuren sure you can get round both ways.
Right, how about the best of both worlds: allow filepath only and fall back to stdin if arg missing.
Both passwords and keys . This implements the design principle that the less secure a solution, the more hackery it requires.

Scenarios:

naive user:

  ethereum account import
  please enter your private key:
  please enter a passphrase:
  Remember your passphrase!
  Oh, and dont forget your passphrase!

geek scripting in public cafe or peeps copy/pasting instructions on stackoverflow:

  ethereum --passwd /path/to/passfile account import path/to/.ethkey.prv >  /dev/null 2>&1

tester:

 ethereum --passwd <(echo 'youcanhackme') account import <(echo '34aebf5689fed6....')

or

ethereum account --unencrypted-keys import <(echo '34aebf5689fed6....')

The same for --unlock and export btw

@zelig I think you misunderstand me.

ethereum --import `cat myFile`      # note this doesn't output anything from cat

Is the same as doing (without the need to actually code it up yourself)

ethereum --import-file myFile

Or does that have any other implications?

@tgerring Oh, thanks :-)

                                                                                  argv can be read by anyone, input can't. 

[zelig]

@obscuren No, I understood you. We can do it both ways: direct input is easier to implement, but with file paths you more actively discourage people from showing their key on screen or record in command history. was my point. so?
