As far as I know hereās not much difference, in general, between the single-dash and double-dash ways of doing it when both ways are available.
There are some options which donāt have the single-dash form and there may be some that donāt have the double-dash form.
There may be some differences for some specific options but those differences should be documented for those specific options.
Iāve been using the single-dash versions almost exclusively and havenāt had any problems yet (except when Iāve used them wrong).
Note: Some double-dash options, for some commands, became subcommands in .NET 7 SDK, so it all gets a bit complicated once you ādive inā.
As for āānameā versus āāoutputā question, I canāt answer that as there may be some specific āunder-the-hoodā details that Iām not aware of.
What I can say about it is that I have been using ā-nā to automatically create the folder name for me without issue ā Iāve never tried ā-oā or āāoutputā.
Sorry for the short reply earlier. At least for me I am using the short hand notation when I am typing in the terminal. It is faster and more lean and I have probably looked at the documentation right before invoking the command. If there are long forms of the options and I have a need to use these commands in a script then I will put in the extra effort to use the long form. This helps me later when I am trying to figure out what my script is doing (might not need to read the documentation again). So thatās how I reason about short vs long forms. What do you guys think?
While Iāve not used dotnet commands in a script I can see where having the command in ālong formā would be useful.
I imagine it makes it easier to spot the options when there are lots of them; for example itās probably easier to accidentally miss something short like ā-dā than it would be to miss something like āādiagnosticsā.
Itās also a kind of free (basic) documentation I guess.
