The command "strace -p ${pid}" is used to trace system calls and signals for a specific process with a given process ID (${pid}).
Here is a breakdown of the command:
-
"strace": This is the main command used for debugging and tracing system calls on Linux systems. It allows you to monitor the interactions between the operating system and a running program.
-
"-p": This option specifies that we want to trace a specific process. Following this option, we provide the process ID we want to monitor.
-
"${pid}": This is a placeholder that represents the process ID of the specific process you want to trace. It should be replaced with the actual process ID when running the command.
By executing "strace -p ${pid}", you can observe and analyze the system calls made by the specified process in real-time. This can be useful for understanding how the process interacts with the operating system, diagnosing issues, and debugging any problems that may arise.
