I have a great performance optimization for this

What if instead of 1s sleep, we did 0.5s sleep? That’s a 100% improvement.

[–] Amanduh@lemm.ee 15 points 3 weeks ago (3 children)

It's not sleeping for 1 second, $1 is an input parameter in the script

[–] wise_pancake@lemmy.ca 4 points 3 weeks ago

That sounds expensive

[–] JackbyDev@programming.dev 2 points 3 weeks ago (2 children)

I took it as meaning sleep for a number of seconds equal to half the value you're sorting. So like f "(( $1 / 2 ))" & or however math works in bash, I always forget.

[–] lurch@sh.itjust.works 1 points 3 weeks ago

Fractional math doesn't happen in bash, but bc can be called and sleep can take fractions as parameters.

I bet you also tell people you love regex because you think it makes you look smarter lol

[–] JackbyDev@programming.dev 2 points 3 weeks ago (1 children)

Well, maybe not with regex, but I'd be lying if I said I never get satisfaction things like that lol. Bash and regex both are very useful tools, great at what they do, but have some design choices that make them annoying. That's sort of what I was trying to get at by saying "yes but also skill issue" lol. A good example is iterating over output in bash. I have zero confidence it's going to do anything remotely close to what I want and have to look up stuff every time I'm trying to do it. "Is it going to go word by word? Line by line? Are there null byte separators?" PowerShell seems appealing in that regard because it works with objects instead of text, but I haven't really used it in depth and I don't see myself going through it just to see if it's worth trying to use more often.

Cool story bro

What if you do love regex? 🥺

[–] Amanduh@lemm.ee 1 points 3 weeks ago (1 children)

Then you should be cast into the fires of Mt doom where you belong

[–] jollyrogue@lemmy.ml 1 points 3 weeks ago (1 children)

You wouldn’t say that if you knew regex. 😆

[–] Amanduh@lemm.ee 1 points 3 weeks ago (1 children)

Programmers and being smug assholes, name a more iconic duo

[–] jollyrogue@lemmy.ml 1 points 3 weeks ago

Project much?

I’ll play though.

Amanduh being a humorless chore. 😁

[–] lurch@sh.itjust.works 0 points 3 weeks ago (1 children)

the idea isn't wrong tho, as sleep can do fractions. bash cannot though. therefore it would bloat the code a bit to use bc to multiply the parameter by 0.5 or so.

[–] Amanduh@lemm.ee 1 points 3 weeks ago

It isn't what is happening though lol...
