gnupg: Scdaemon Configuration
6.4 Configuration files
=======================
There are a few configuration files to control certain aspects of
'scdaemons''s operation. Unless noted, they are expected in the current
home directory (⇒option --homedir).
'scdaemon.conf'
This is the standard configuration file read by 'scdaemon' on
startup. It may contain any valid long option; the leading two
dashes may not be entered and the option may not be abbreviated.
This default name may be changed on the command line (⇒option
--options).
'scd-event'
If this file is present and executable, it will be called on every
card reader's status change. An example of this script is provided
with the distribution
'reader_N.status'
This file is created by 'scdaemon' to let other applications now
about reader status changes. Its use is now deprecated in favor of
'scd-event'.
