Instead, the commands it invokes as part of the script will each individually write output and flush whenever they feel like it So your question is really how to force the commands within the bash script to flush, and that depends on what they are. If wondering if there's any way to interact with a running python script (or, more generally, a running process) to force it to flush its output buffer. You can control a command's output buffering using stdbuf By using tools like stdbuf (most portable), unbuffer (for stubborn commands), or script (terminal simulation), you can force output to flush immediately to the log file. 4 do you have access to the source of the running programs
Forcing a flush of an arbitrary executable is, while not theoretically impossible, very difficult You would need to find the fflush function in the code and the stdout argument, then interrupt the execution of the program, arrange for the call to fflush, then continue execution. 2 if you force the file to be read, it seems to cause the buffer to flush Either read the data into a useless variable:
OPEN
