truss: Start tracing a specific process by its PID.

truss

$ truss -p ${pid}

try on your machine

The command "truss -p ${pid}" is used to trace system calls and signals of a running process with the specified process ID (${pid}).

Here's a breakdown of the command:

"truss": This is a command in Unix-like operating systems, typically available in systems like Solaris and FreeBSD. It is used to trace the system calls, signals, and other events of a running process.
"-p": This flag is used to indicate that the process ID of the target process will be provided.
"${pid}": This is a placeholder that represents the process ID of the process you want to trace. You would replace it with the actual process ID when running the command.

When you execute "truss -p ${pid}", the command will attach itself to the specified process (${pid}) and begin tracing the system calls and signals that the process makes. This can be useful for debugging or understanding the behavior of a program by observing its interactions with the operating system.
