Wow, that is an unhelpful error message. It could have told you it was expecting a number. It turns out that -i is short for "interval" and expects a number, whereas -I is used to specify an interface.
Itās actually a technical term in language theory ā a term that cannot be produced by the language, but is still considered part of the āuniverseā (i.e., the set of all terms) is called āgarbageā or ājunkā.
Since I canāt find a source online to verify this claim, this might just have been the case in my coursesā¦
"Invalid" or "unparseable" are more understandable descriptors in normal language. I don't think I ever heard of garbage/junk being used for that in language theory but it may be domain specific usage.
There might be a reason it was never fixed. Something stupid like a lot of 30 year old scripts relying on this out come. Hope not, you're right that error message is ass

-iis short for "interval" and expects a number, whereas-Iis used to specify an interface.This exactly. And because this is open-source, its super easy to track this down. I searched for the source of the error message:
https://github.com/iputils/iputils/blob/3400f3a740942064a545f02aabcf68e234733297/ping/ping.c#L237
see this is
ping_strtodfunction - so search for that function name and the first hit is the '-i' case:Hahahahah you just doxed yourself hahahahah
Ahh yes get doxed through local ip XD
Woooooosh

See, even ping hates "consistent device naming!"
Good old git blame lol! Not only can you determine when the change was made and where, itās trivial to look up the author of the commit: https://github.com/iputils/iputils/commit/562e0d570d93cfcfdebab1215a2f04efa64a24f8
To be fair, the authorās first language may not be Englishā¦
Is anyone interested in submitting a pull request? Looks like Github contributions are accepted.
My dude. It's not a bug, OP just used small i instead of capital. Please don't bother developers over this.
I think descriptive and useful error messages are OK to report as enhancements. They donāt have to be functional bugs.
