how to put history=0 in command prompt - sylas - May-23-2018
Hi all! I have about 100 commands possible in command prompt. Most of them are repeated. "history" alone shows these possible commands. But impossible to delete them. Here my error messages;
Error:
C:\Users\Sylvain
λ reset history

Sylas, please post in the correct subforum! This has nothing to do with python to be in the General Coding Help subforum... or even better - ask in the correct forum: https://www.google.com/search?q=windows+help+forum

Do you think I will ever have a reply in this Bar forum ? I don't think so. Who looks at this Bar forum ?
RE: how to put history=0 in command prompt - buran - May-23-2018
This is python related forum and this is off-topic question. I would expect that if someone know the answer, they will help. If you are not satisfied, you can ask on windows-related forum.

Try
history -c.Cygwin right? The bash command to clear the history is history -c

Thanks for your reply. I tried it on my "C:\Users\Sylvain". It does not work. I think there is a question of "Administrator". But I don't know how to become Administrator once I am on my Command Prompt.
RE: how to put history=0 in command prompt - buran - May-23-2018
I don't think you can elevate priviliges once cmd is open. You can either right-click cmd.exe and select Run as administrator OR press windows key+R, then enter cmd in the run window that will open and press cntrl+shift+enter

Thanks to Buran. I tried your 2d proposal. It works fine. At the top of my command prompt ihave: C:\WINDOWS\system32\cmd.exe
And inside I have:
Microsoft Windows [Version 10.0.17134.48]

C:\Users\Sylvain>set history

C:\Users\Sylvain>history=10

Hm! I don't remember if the cygwin has .bashrc file. Try to find it. See this: https://www.cygwin.com/cygwin-ug-net/setup-files.html
Put at the end of file on a new line this: HISTSIZE=0
Save the file and run cygwin again.

With a double right click on lambda(on the pinned icons at the bottom of the screen)my lambda is transformed; Now I am sure I am Administrator. The new command prompt accepts "set history=10", but does not accept "HISTSIZE=10". I am not strong in python, so I don't understand your "cygwin". I went to your link.
Error:
C:\Users\Sylvain
λ HISTSIZE=10
'HISTSIZE' is not recognized as an internal or external command,
operable program or batch file. How is it possible you two big members of the staff, cannot solve this problem: put history = 10 ? With linux, no problem. Please go to this lambda icone, right click twice, become administrator and tell me if you can limit the possible commands, to ten. Thanks
