Arguments can be used to override the entrypoint when running Docker commands by specifying a different command to be executed after the image is launched.

This can be done by adding the command to the end of the docker run command followed by any necessary arguments. For example, to override the entrypoint of an image called my-image and run a command to print "hello world", the following command can be used:

docker run --entrypoint=/bin/sh my-image -c "echo hello world"

In this case, the --entrypoint flag sets the new entrypoint to /bin/sh, and the command to be executed is specified after the image name using the -c flag to run the command in a shell.
