[Bro] Calling external scripts on extracted files

[Vikram Basu]

Hi,

I am using the bro file-extraction script from the bro-pkg manager and want
to run a python script as soon as the file is completely extracted.

Currently I am calling the script using the Bro Exec::run command after
modifying the script but often times the script is running before the file
has finished extracted and is failing as a result.

How can I make it so that Bro calls the script after file has already been
extracted?

I thought maybe using file_state_remove would help but even in that case I
am getting
/Input::READER_RAW: Child process exited with non-zero return code 127
which I am assuming means the script was run before the file as truly
extracted?

Any advice would be much appreciated.

Regards

Vikram
