Multi Process Tracing with Strace

This Python script allows you to trace one or more running processes using the strace command-line tool from a single application. It finds processes by their PID from the application name and creates a log file for each traced process.

Prerequisites

• Python 3.x
• strace tool (available on most Linux distributions)
• psutil Python library (install it using pip install psutil)

Usage

1. Clone or download this repository to your local machine.

2. Open a terminal and navigate to the directory where the script is located.

3. Run the script with the following command:

   python3 pypidtrace.py <target_process_name>

   Replace <target_process_name> with the name of the process you want to trace.

4. The script will create log files for each traced process with the format trace_pid_<pid>.log, where <pid> is the process ID of the traced process.

5. Once the tracing is complete, the script will check if the traced processes have exited and report their status.

Example

To trace a process named "myapp," run the following command:

python3 pypidtrace.py myapp

The script will start tracing all processes named "myapp" and create log files for each traced process.
