Hi @programista-zacny
Find similar issue #13352.

Issue title	az container exec in azure devops throws (25, 'Inappropriate ioctl for device')
Create time	2020-05-06
Comment number	21

Possible solution:
The error message "Inappropriate ioctl for device" is thrown when trying to use az container exec in Azure DevOps Pipelines. One solution to this issue is to emulate tty using the following command:

script --return --quiet -c "az container exec --resource-group myRG --name myImageName --exec-command ./run.sh'" /dev/null

This should allow you to display the output of the container and pipe the result to a file.

Hi @programista-zacny

Thanks for reporting this issue.
May I ask what is the device and scenario for executing the command?

Hi @programista-zacny

Can you help me to double confirm the result of the execution of these python code on MacOS Sonoma 14 on MacBook Air M2?

from shutil import get_terminal_size
size = get_terminal_size()
print(size) 

Thanks.

[programista-zacny]

Result: os.terminal_size(columns=200, lines=50)
I run this on iTerm.
