.TH git-annex-forget 1
.SH NAME
git-annex-forget \- prune git-annex branch history
.PP
.SH SYNOPSIS
git annex forget
.PP
.SH 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 \fBgit annex log\fP will not be able to show where
files used to be located.
.PP
When this rewritten branch is merged into other clones of
the repository, \fBgit-annex\fP will automatically perform the same rewriting
to their local \fBgit-annex\fP 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.)
.PP
.SH OPTIONS
