Issue Details
We have a container which output logs via pino. When the output is not formatted the terminal will continuously blink as I assume the CLI compares the requested log to the currently printed one and updates the terminal with the latest lines. However when we pipe the output of the command to `pino-pretty` which formats the log statement to human readable format, the CLI will continuously print the same lines over and over again in every refresh cycle. (As I assume it cannot find a match between the received value and what is printed in the terminal. ### Actual behavior Let's say we have a container what prints one and only one line of message. When running the following command: ``` az container attach --resource-group rg-my-resource-group --name aci-my-container ``` The terminal will display that line once, but the terminal will keep blinking as the content is updated. However when running the following command: ``` az container attach --resource-group rg-my-resource-group --name aci-my-container | pino-pretty --colorize ``` The output from the container will be printed over and over again for every refresh cycle. ### Expected behavior I would expect that the Azure CLI keeps an internal buffer of received messages, calculates the difference internally and only prints to the console when a new line is received. --- #### Document Details ⚠ *Do not edit this section.
