Example tvscript Script File
The following information is passed to tvscript as follows:
tvscript -script_file script_file
This script installs an error handler and an action point handler. When an error is encountered during execution,
tvscript passes an array of information to the error handler. Similarly, when an action point is hit, it passes an array of information to the action point handler. These arrays are described in
“Event API”.
# Get the process so we have some information about it
tvscript_log "PID: \
[tvscript_get_process_property 1 "syspid"]";
tvscript_log "Status: \
[tvscript_get_process_property 1 "state"]";
tvscript_log "Executable: \
[tvscript_get_process_property 1 "executable"]";
