This script is a work by Webmaster Seth Leedy, but was inspired by and evolved from the scripts by [email protected]


I noticed that I was mentioned in the Security Now show(epi: 457, 558). Yipee!


Download any or all Steve Gibson’s GRC Security Now podcasts via a bash script.
The script can look at the episodes already downloaded and download the next one.
You can specify the episode(s). Download 1 or a range.
Another function is to search for text within ALL the episodes and copy the episode text to another directory for further reading.
Run it with “-h” for all the other options.


The code is now on GitHub ! Feel free to help develop it or fork it.

You can submit issues within GitHub or via email to me. Comments below are not actively monitored…
