truss -f {{program}}
- 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}}
