 Shell command with different working directory.

Examples:

Create a new account:
  curl -u sk_abcdefQWERTY090900000000: \\
    -d first_name=John00 \\
    -d last_name=Doe00 \\
    -d email_address=jd@some_email \\
    -d password=xyzabc09090 \\
    -d agreed_to_terms=true https://cocalc.com/api/v1/create_account

Option 'agreed_to_terms' must be present and specified as true.
Account creation fails if there is already an account using the
given email address, if 'email_address' is improperly formatted,
and if password is fewer than 6 or more than 64 characters.

Attempting to create the same account a second time results in an error:
  curl -u sk_abcdefQWERTY090900000000: \\
    -d first_name=John00 \\
    -d last_name=Doe00 \\
