On terminals it enables line buffering, i.e. the accumulated output is flushed when a newline character is reached. Otherwise it uses a system-dependent buffer size in the range of a few kilobytes. You can check if your output is a terminal e.g. with: python -c "import sys; print(sys.stdout.isatty())" You can disable buffering by running your script with "python -u". This discussion mentions more options: https://stackoverflow.com/questions/107705/disable-output-buffering You can also start bash on the command line. I do wonder why Git CMD seems to be started in what passes as a terminal, while Git BASH is not, though. You may want to check out https://gitforwindows.org/ and report your findings using their issue tracker. (This mailing list here, git@xxxxxxxxxxxxxxx, is mostly used for discussing Git itself, not so much about extra tools like bash or Python that are packaged with Git for Windows.) René
