Can I clear an NCache cache without confirmation?

Question

I've got an NCache implementation (configured in replicated format across a pair of servers, if that makes any difference) and I want to script clearing the cache. I've got a powershell script that calls the NCache clearcache.exe tool (in \bin\tools) with the appropriate parameters, but the tool then prompts me for confirmation that I actually do want to clear a non-empty cache (why yes, I do!).

I've looked at the inline help for the command (scanty) and in the NCache documentation online (http://www.alachisoft.com/resources/docs/ncache/help/main.html) without any luck for help with additional parameters (like a --force option or the like).

Is there any such option that would allow me to clear the cache without having to interact with the script? Is there another path to accomplishing the same thing?

Thanks, David - can you make this an answer so I can mark it accepted? — cori, Jan 29 '16 at 14:24

If you look at page 35 here (NCache Command Line Tools guide), you'll see that you can use /F to force a clear cache.

I found that the "/F" was case sensitive; using lower case I received an error about the server details not being configured in the client config (although they were). Switching to upper case resolved the issue. – cori Jan 29 '16 at 15:48

Open CMD and go to NCache installation folder then bin/tools For me it's C:\Program Files\NCache\bin\tools

run clearcache.exe /? you'll get

C:\Program Files\NCache\bin\tools>clearcache.exe /?

Alachisoft (R) NCache Utility ClearCache. Version 4.6.0.0

Usage: clearcache cache-name [option[...]].

Argument:

Specifies one or more name(s) of caches separated by space registered on
the server. The cache(s) with this/these name(s) is/are started on the
server. Note: Space-separated cache names are to be specified in case of
multiple caches.

Option:

/F /forceclear

clearing the cache.

well, in the version of ncache that we're running the /F option does not show up in the /? help, so that was of no help to us. @David Brabant's answer pointed us to the actual docs online. – cori Feb 03 '16 at 12:35
That's odd. Can you open up an issue ? https://github.com/Alachisoft/NCache/issues – Basit Anwer Feb 04 '16 at 05:54
Of course we're on 4.4, so perhaps that's the issue. – cori Feb 13 '16 at 03:13
Well, it should be there nonetheless. – Basit Anwer Feb 13 '16 at 05:55
