The \module{getpass} module provides two functions:
|
||
|
|
|
||
|
|
|
||
|
|
\begin{funcdesc}{getpass}{\optional{prompt}}
|
||
|
|
Prompt the user for a password without echoing. The user is
|
||
|
|
prompted using the string \var{prompt}, which defaults to
|
||
|
|
\code{'Password: '}.
|
||
|
|
\end{funcdesc}
|
||
|
|
|
||
|
|
|
||
|
|
\begin{funcdesc}{getuser}{}
|
||
|
|
Return the ``login name'' of the user.
|
||
|
|
|
||
|
|
This function checks the environment variables \envvar{LOGNAME},
|
||
|
|
\envvar{USER}, \envvar{LNAME} and \envvar{USERNAME}, in order, and
|
||
|
|
returns the value of the first one which is set to a non-empty
|
||
|
|
string. If none are set, the login name from the password database
|
||
|
|
is returned on systems which support the \module{pwd} module,
|
||
|
|
otherwise, an exception is raised.
|
||
|
|
\end{funcdesc}
