PCSC-SPY(1) User Contributed Perl Documentation PCSC-SPY(1) NAME pcsc-spy - A PC/SC spy command SYNOPSIS pcsc-spy [-n|--nocolor] [-d|--diffable] [-h|--help] [-v|--version] [-t|--thread] [fifo_filename] DESCRIPTION pcsc-spy displays PC/SC calls of an application. It must be used with the libpcscspy.so.0 library. To be able to spy the PC/SC layer, the application flow must be modified using "LIBPCSCLITE_DELEGATE" so that all PC/SC calls are redirected. OPTIONS -d, --diffable Remove the variable parts (like handler values) from the output so that two execution can be more easily compared. -h, --help Display a short help text. -n, --nocolor Disable the output colorization (if you want redirect the output in a file for example). -v, --version Print the version of the pcsc-spy program plus a copyright, a list of authors. -t, --thread Add a thread number before each line of log to identify the calls from the same threads. EXAMPLES We will use the "LIBPCSCLITE_DELEGATE" environment variable to load our spying library. Example: sh /usr/share/doc/libpcsclite-dev/setup_spy.sh export LIBPCSCLITE_DELEGATE=/lib/x86_64-linux-gnu/libpcscspy.so.0 LIBPCSCLITE_DELEGATE=/lib/x86_64-linux-gnu/libpcscspy.so.0 my_application Starting the spy tool pcsc-spy If a command argument is passed we use it instead of the default ~/pcsc-spy FIFO file. It is then possible to record an execution log and use pcsc-spy multiple times on the same log. To create the log file just do: mkfifo ~/pcsc-spy cat ~/pcsc-spy > logfile and run your PC/SC application. FILES ~/pcsc-spy FIFO file is used by libpcscspy.so.0 to send the raw log lines SEE ALSO pcscd(8) AUTHOR This manual page was written by Ludovic Rousseau <rousseau@free.fr> perl v5.42.3 2024-01-01 PCSC-SPY(1)
