`conda run` will clear the terminal output

[TanKimzeg]

similar to #496

conda runscripts appear at:

• L366
• L460
• L823

--live-stream: This option ensures that the standard output (stdout) and standard error (stderr) of the executed program are not captured or buffered. Instead, the output is streamed live to the terminal as the program runs.

Even without the --live-stream flag, the terminal's previous output is automatically cleared – similar to executing a cls/clear command, which is inconvenient for users to compare results.

conda run  --live-stream -n base python -c "print('Hello')"
conda run -n base python -c "print('Hello')"

If the conda env is already activated , run

python foo.py

or

D:/Miniconda/envs/<env>/python.exe  foo.py

can avoid conda run.

Hi! Thanks for the issue report. Are you saying here that conda run does the terminal clear automatically and that this is problem here?

seems related to #640

Hi! Not hitting this when I try it, do you have any specific settings?

My platform is Windows 11, and it happens in both PowerShell and cmd.

It seems to be caused by conda's own scripts.VScode is configured with the suggested settings of the python-env extension.

Another Win 10 machine, without python-env extension.

I encountered a similar issue. After checking Conda's GitHub issues, I found an unresolved thread dating back to 2022, indicating this may be a long-standing problem.
