Hi, The man page for git documents the -p option to _enable_ the paginated output for git, which isn't very usefull since the commands that might actually need paging have it enabled by default. What I can't find is a clean way to _disable_ the pager. A hacky way is to run "git whatever | cat", or "GIT_PAGER=cat git whatever". From the code, it seems that git doesn't even launch the pager if it's set to "cat". I think that deserves an less-hacky, and documented way. I'd suggest a --no-pager, or --dont-paginate, that would do the opposite of -p as a global option for git. Below is a patch that does this:

From: Matthieu Moy <redacted> Date: Sun, 19 Aug 2007 19:24:36 +0200 Subject: [PATCH] Add and document a global --no-pager option for git. To keep the change small, this is done by setting GIT_PAGER to "cat". I'd prefer not using global/environment variables for that, but it would require a complete refactoring of options handling in git. --- Documentation/git.txt | 6 +++++- git.c | 6 +++++- 2 files changed, 10 insertions(+), 2 deletions(-)
