Total Commander

Yes, for example /O:-1 would do the same as OnlyOnce=-1.

Aren't you confused by the presence of the '-' sign in front? Somewhat unusual for a parameter.

No, he means it can be any value of the ini setting OnlyOnce. So it can be any positive and negative number and zero.

I got that there will be several values, one of which is with a minus sign, which is confusing.

Well, don't look at me. I don't agree with any of it

The /N option was meant to create a new instance when it would otherwise (without the parameter) not be created.
The /O option was meant to prevent a new instance when it would otherwise (without the parameter) be created.

Passing paths is optional and passing paths to an already running TC is not unique for the /O parameter. It also happens without the parameter when only 1 instance of TC is allowed. The /O parameter was only meant to override the setting to create a new instance, thus preventing it and causing the paths to be passed to the running instance. This is how it is explained in the Help. This is how it worked before.

And this is how it was added in Windows Commander 3.50:

Wiki - List of changes wrote: (16.08.97) Added: When only 1 instance, a second instance passes the command line (paths) to the previous instance
(16.08.97) Added: New command line switches: /O activates previous instance, /N creates multiple instances of Wincmd

I still remember when these options were added and thought they were very cool options.

But Ghisler changed it and his reasoning now is that the main purpose of /O is to pass paths to an already running instance of TC and to disregard the OnlyOnce setting completely. Its purpose is no longer to override the setting, but to completely ignore the setting and do its own thing.

This sounds more like an explanation of how he programmed it since TC version 7.55.

Exactly. Returning to this statement

ghisler(Author) wrote: 2022-08-25, 08:32 UTCBut the user does want to open these new directories! So the logical consequence is to open a new copy of TC with these paths.

, I forgot to point out the condition where the presence of paths is not mandatory for uncharacteristic behavior:

That is, at a minimum, it is necessary to exclude the launch of the second instance in case of a lack of paths, regardless of the availability of new options.

Exactly!
white words it as if I changed this deliberately to piss off people, but that isn't my intention. The main idea of /O is opening directories, if possible in an already running instance, otherwise in a new instance. It's not meant to prevent the launching of a second instance at all cost, that would need a new parameter.

I'm moving this thread to suggestions because the current behaviour is intentional and a new parameter is needed for what is wanted here (no new instance in any case).

OK. But do you agree with my previous thesis that the second instance without paths should no longer run?
And answer about the minus, please.

ghisler(Author) wrote: 2022-08-26, 09:32 UTCno new instance in any case

Reaction.

Why do you find it funny now? First you request it than then you make fun of it? I don't understand what you want.

I thought that you were being ironic in parentheses, because this is an obvious thing that it makes no sense to write about seriously as an irritant that should be eliminated. I thought it was obvious.
Answer the questions, please.

Somewhere in this thread the discussions lost some simple facts and it cycles in a loop

Am I right that everyone would be happy if TC would accept a new command line parameter (e.g. /O!) which would not open a new TC instance under any circumstance?

Not sure about Horst.Epp, he somehow resisted it.

I'm happy with the current implementation
So for me any additional switch is fine.
but for me its looks like the changes Christian suggested are still lead to endless discissions.
