• Start tracing a specific process by its PID:

truss -p pid

• Start tracing a program by executing it, showing arguments and environment variables:

truss -a -e program

• Count time, calls, and errors for each system call and report a summary on program exit:

truss -c -p pid

• Trace a process filtering output by system call:

truss -p pid -t system_call_name
