Scrolling terminal output in Emacs

Scrolling terminal output in Emacs

[Galen Boyer]

I'm sure this has been asked 100 times I'm just not sure how to pinpoint
the description so I'm not finding the answer.

I just downloaded and set myself up for using Ubuntu on Windows.  I've
gotten my Emacs/Cygwin workspace on windows mimic'd on Ubuntu with
Cygwin.

But, when I kick off some commands, such as "git diff XXX" the output
gives me a page and then the ":".  Is there a way to tell my environment
I never want pagination?  I want it all to come to the "console".  Of
course I want that because I can scroll the output with Emacs.

By default, git sends its output trough a pager (when it thinks there is
a terminal at the other end). You can change that by invoking commands
with the option --no-pager or by setting the PAGER environment variable
accordingly (see git's manual page) or by setting some pager.XXX config
variables.

This worked for git but then I get the same behaviour from other
command-line scripts, for example, GCP's gcloud.  But found the
following
https://stackoverflow.com/questions/62675616/how-to-get-non-interactive-text-output-with-gcloud-help-command

This idea,

    export PAGER=cat
    gcloud --help

So, tried that and it worked for gcloud.  Went back to git and it also
worked for that.

Thanks for the --no-pager.  In the end, that actually allowed me a better google
search term which was truly my initial reason for having to post a question.
