Hey Linux users! Do you trust untested AI-generated bash scripts

Do you trust Ai-Generated bash scripts

Yes

No

Assume that you checked the script to make sure the script did what you wanted to do and that it's safe (eg, no rm -rf when you're not deleting something, or unnecessary use of sudo, etc) but you didn't test the script on a VM, test server, etc.

Personally, my answer is no, because I don't trust AI, and I believe you should always test all your bash script (unless they are super simple)

I just wrote a bash script to take either one URL or a list of URLs in a text file, fetch the URL(s), strip the HTML tags so it’s only text, and get a word count. This will let me feed it a bunch of URLs of really old Xena fanfic and get more-or-less accurate word counts - back in the day we didn’t assess size in terms of word count, but file size. So in order to do my XWP fic recs right I’m determined to include a word count even on the really old stuff.

Oh, and it also totals the word count when it’s done so I can grab multiple URLs for a series broken up into chapters.

could I have been manually collecting that data on my own for the last hour instead of writing a script? yes

was this much, much more fun and will save me time and drudgery in the near future? also yes

am I huge, huge nerd who needs a life? fuck yes

(also, if anyone participating in the XWP lockdown fic rec wants the script or would like me to run up a word count for you, let me know)

Matrix Reimagined: Crafting Digital Rain with Bash and ChatGPT

Just for fun, and I have no idea why I thought about it, I decided to work with ChatGPT (4) to build a simple bash-based version of the Matrix Digital Rain. I know there’s already better versions, like cmatrix, but we do not do things because they are easy. We do them because we are bored. I’ve asked ChatGPT to heavily comment the code for us so that we can see exactly what’s going…
