Re:How to securely manage credentials in shell scripts? on Monday May 26, 2025 @05:16PM (#44101762)

I have a bunch of scripts and a bunch of sysadmins who do not need to know those credentials but should based on their username be able to use the scripts. Those scripts query specific aspects of network infrastructure up to now via ssh.

How to securely manage credentials in shell scripts?

I need to improve security over a set of shell scripts which have hardcoded credentials. I’m wondering what is the state of the art on this subject. I’ve read about gpg, hashicorp vault, pass command, but still wonder what you guys are doing.

Is there any website to get duly updated on this super awesome courses? The OCW MIT site is not even reflecting that this edition of the course was released.

Similar example to this one... latest publishing of CS193P (iOS Development) was released a few months back, its awesome, but no traces of it on iTunes or other sites, found it on Twitter, so I have the feeling I am missing many of these..

Re:Ask HN: What are good life skills for people to learn? on Sunday September 27, 2020 @08:40AM (#24606206)

Cooking (proper food not junk), growing your own food, personal finances, how to manage emotions, carpentry, welding, how to enjoy time by your own, languages (the more the better), how to do basic fixing of appliances (see RepairCaffe), learn the joy of not to stop learning, sleeping habits, health habits, be conscious what you want at work to be happy (depressed Manager or happy technician)...

To be continued... nice thread!
