truss: Count time, calls, and errors for each system call and report a summary on program exit.
$ truss -c -p ${pid}
try on your machine
The command "truss -c -p ${pid}" is used to trace the system calls made by a specific process identified by its process ID (pid).
Here is a breakdown of the command:
- "truss" is a command-line tool used in Unix-like operating systems (such as Linux) to trace system calls, signals, and other events in programs.
- "-c" option instructs truss to display system call counts for each unique call.
- "-p" option is used to specify the process ID of the target process.
- "${pid}" is a placeholder that denotes the actual process ID you want to trace. You need to replace "${pid}" with the actual process ID number while executing the command.
Overall, this command will capture the system calls made by the specified process and provide a count of each unique system call. It can be useful for diagnosing and troubleshooting issues in the target process by analyzing the system calls it makes.
