# NAME

git-annex forget - prune git-annex branch history

# SYNOPSIS

git annex forget

# DESCRIPTION

Causes the git-annex branch to be rewritten, throwing away historical
data about past locations of files. The resulting branch will use less
space, but `git annex log` will not be able to show where
files used to be located.

When this rewritten branch is merged into other clones of
the repository, `git-annex` will automatically perform the same rewriting
to their local `git-annex` branches. So the forgetfulness will automatically
propagate out from its starting point until all repositories running
git-annex have forgotten their old history. (You may need to force
git to push the branch to any git repositories not running git-annex.)

# OPTIONS

* `--drop-dead`

  Also prune references to repositories that have been marked as dead.
