As I mentioned in the PR comments, I'd also suggest we include some form of "hostname" in here, even if we don't currently choose to validate it, e.g.

PROMPT=$E]7;file://%COMPUTERNAME%/$P$E\$P$G

I'd also probably leave the $S off the end if we're planning to publish this as a recommendation. If some people prefer to have a space on the end, that's obviously their choice, but I think our recommendation should match the default format, which I believe is just $P$G.

better use %%COMPUTERNAME%% otherwise the variable will only be evaluated when this command is executed

That doesn't seem to work for me. It just ends up evaluating to %COMPUTERNAME%. I don't think it's the end of the world if we can't get it to update when the machine name changes though. That's not likely to be often is it?

does it print %COMPUTERNAME% or is it stored as that?

It prints the literal text %COMPUTERNAME%. Maybe I'm just being stupid, but I was testing by using a sequence without escapes, so I could see what was being produced. Basically something like this:

PROMPT=Esc]7;file://%%COMPUTERNAME%%/$PEsc\$P$G

And the sequence I saw being output was something like this:

Esc]7;file://%COMPUTERNAME%/C:\pathEsc\

Without the double percent chars that shows my actual computer name.

I should mention that this is with the PROMPT being set in a batch file. If I set it directly from the command line, then my computer name is displayed, but with percent chars on either side.

oh, I know what's going on, its my fault, the double % strategy only works if using setx like this:

 setx PROMPT "$E]7;file://%%COMPUTERNAME%%/$P$E\$P$G"

then restart cmd

OK, I see what you were getting at now - this works for me. I misinterpreted what you said about the variable only being evaluated the first time, so I thought at first that this version would update in "real time" (i.e. if the computer name changed during a particular session), but that's definitely not essential. This is good enough for me.

It doesn't work for me. I'm using it to open new tabs/splits in Windows Terminal in he same directory. Your powershell prompt worked. But for cmd this appears to do nothing.

yeah you have use osc]9;9 for it to work on wt rn
