gnupg: Invoking GPG-AGENT

 
 2 Invoking GPG-AGENT
 ********************
 
 'gpg-agent' is a daemon to manage secret (private) keys independently
 from any protocol.  It is used as a backend for 'gpg' and 'gpgsm' as
 well as for a couple of other utilities.
 
    The agent is automatically started on demand by 'gpg', 'gpgsm',
 'gpgconf', or 'gpg-connect-agent'.  Thus there is no reason to start it
 manually.  In case you want to use the included Secure Shell Agent you
 may start the agent using:
 
      gpg-connect-agent /bye
 
 If you want to manually terminate the currently-running agent, you can
 safely do so with:
 
      gpgconf --kill gpg-agent
 
 You should always add the following lines to your '.bashrc' or whatever
 initialization file is used for all shell invocations:
 
      GPG_TTY=$(tty)
      export GPG_TTY
 
 It is important that this environment variable always reflects the
 output of the 'tty' command.  For W32 systems this option is not
 required.
 
    Please make sure that a proper pinentry program has been installed
 under the default filename (which is system dependent) or use the option
 'pinentry-program' to specify the full name of that program.  It is
 often useful to install a symbolic link from the actual used pinentry
 (e.g.  '/usr/bin/pinentry-gtk') to the expected one (e.g.
 '/usr/bin/pinentry').
