Textual authentication helper


' pkttyagent 'u pkttyagent [ --version ][ --help ] ' pkttyagent 'u pkttyagent [ --process { pid | pid,pid-start -time } | --system -bus -name busname ][ --notify -fd fd ][ --fallback ]


If the authentication agent could not be registered, pkttyagent exits with an exit code of 127 . Diagnostic messages are printed on standard error .

If one or more of the options passed are malformed, pkttyagent exits with an exit code of 126 . If stdin is a tty, then this manual page is also shown .

If the authentication agent was successfully registered, pkttyagent will keep running, interacting with the user as needed . When its services are no longer needed, the process can be killed .


Since process identifiers can be recycled, the caller should always use pid,pid-start -time when using the --process option . The value of pid-start -time can be determined by consulting e .g . the proc (5) file system depending on the operating system . If only pid is passed to the --process option, then pkttyagent will look up the start time itself but note that this may be racy .


Please send bug reports to either the distribution or the polkit -devel mailing list, see the link on how to subscribe .


pkttyagent is used to start a textual authentication agent for the subject specified by either --process or --system -bus -name . If neither of these options are given, the parent process is used .

To get notified when the authentication agent has been registered either listen to the Changed D -Bus signal or use --notify -fd to pass the number of a file descriptor that has been passed to the program . This file descriptor will then be closed when the authentication agent has been successfully registered .

If --fallback is used, the textual authentication agent will not replace an existing authentication agent .
