ls -r actually lists entries in reverse order! It needs -R as well.
cp and rm accept either.
Looking at some man pages the only commands I found where -R didn’t work were scp and gzip where it doesn’t do anything, and rsync where it’s “use relative path names”.
(Caveat: BSD utils might be different, who knows what those devils get up to!)
Not chmod related, but I’ve made some other interesting mistakes lately.
Was trying to speed up the boot process on my ancient laptop by changing the startup services. Somehow ended up with nologin never being unset, which means that regular users aren’t allowed to log in; and since I hadn’t set a root password, no one could log in!
Installed a different version of Python for a project, accidentally removed the wrong version of Python at the end of the day. When I started the computer the next day, all sorts of interesting things were broken!
Aha! I didn’t get that you meant the issue was accidentally using -r instead of -R since both you and OP wrote the upper case one.
I’m a lot more used to -R so I instead get caught off by commands where that means something other than recursive :)
I mostly use symbolic mode and honestly don’t get why everyone else seems to use octal all the time.
That’s what -R does in chmod as well? I feel like something here is going completely over my head. Or are you-all using another version of chmod?
If “All rights reserved” means “I, the rights holder, reserve the usage of all copy rights for myself only. You have no such rights.” then “All rights refused” must mean “I, the rights holder, refuse all copy rights to this work. You can do whatever.”
I guess I like it because it’s catchy and aggressively anti-copyright.
But if you’re actually going to release something where copyright might become an issue it’s of course better to use a real license like CC.
I like All rights refused
Same here. They have an open source graphical client you can use or they can generate an OpenVPN profile for you. Easy to use, high speeds, good price and they support port forwarding.
I had a similar task to
“Set up a web service, load balancer and infrastructure to scale it to handle a large amount of requests. Harden the security of it to the best of your ability. Document how it works, how to scale it, why you built it the way you did, what measures you took to harden it and why, and any future improvements you would suggest. All code and documentation should be production quality. This should take about four hours.”
Maybe you can write this code in four hours, but all this documentation and motivation as well? Fuck off.
They also asked for a made up report from a security audit (this was for a security engineer position) containing a dozen realistic vulnerabilities with descriptions, impact assessments, and remediation suggestions. Once again of production quality. This is at least six pages of highly technical, well researched, and carefully worded text. Four hours is tight for this task alone.
