wget -O needs to be passed as first argument

https://github.com/DeterminateSystems/nix-installer/blob/5a58cf20bec1b34f62e11709a60ed60d2d640353/nix-installer.sh#L314 doesn't work.

Only wget -O /tmp/nix-installer https://install.determinate.systems/nix/tag/v0.8.0/nix-installer-x86_64-linux works, but most tools pass -O after URL, not before.

-O should not be positional and only working if provided as first argument...

When applied on top of #2668 manually packed under u-root cpio:

~ # wget  https://install.determinate.systems/nix/tag/v0.8.0/nix-installer-x86_64-linux -O -O /tmp/nix-installer
~ # ls /tmp/nix-installer 
ls: /tmp/nix-installer: No such file or directory

I see -O twice, are you sure it did not pull it down to a file name -O?

[rminnich]

it's not that it is positional, it's that the go flag package takes the standard of switches first and then args.

wget's rules around args are very non-standard, but we have little choice but to honor them, including the -- I suppose. Quite the mess.

Bad copy paste

man wget | grep '^ *--'|wc
wow. 174 options.
This is truly a work of art.

@rminnich yeah... Sometimes less is more.
Idea is not to try to replicate all of them, but i'm not sure it's acceptable that -O is not respected after an URL. I kinda agree that src:dst idiom is applied in all scripts I have came across. Kinda weird to expect dst:src.

Nothing can be done here? Even if ugly, if wget is dealing only with one argument (-O) it should tolerate having dst passed after source.

Then asking on a use case basis for fix where too tight on expression should be possible for all other u-root applets. But serisouly.... Without wget support, its impossible to get anything "in".
