SYNOPSIS
--------
'git-read-tree' (<tree-ish> | [[-m [--aggressive] | --reset | --prefix=<prefix>] [-u | -i]] <tree-ish1> [<tree-ish2> [<tree-ish3>]])
'git-read-tree' (<tree-ish> | [[-m [--aggressive] | --reset | --prefix=<prefix>] [-u | -i]] [--exclude-per-directory=<gitignore>] <tree-ish1> [<tree-ish2> [<tree-ish3>]])
DESCRIPTION
@ -71,6 +71,20 @@ OPTIONS
directory. Note that the `<prefix>/` value must end
with a slash.
--exclude-per-directory=<gitignore>::
When running the command with `-u` and `-m` options, the
merge result may need to overwrite paths that are not
tracked in the current branch. The command usually
refuses to proceed with the merge to avoid losing such a
path. However this safety valve sometimes gets in the
way. For example, it often happens that the other
branch added a file that used to be a generated file in
your branch, and the safety valve triggers when you try
to switch to that branch after you ran `make` but before
running `make clean` to remove the generated file. This
option tells the command to read per-directory exclude
file (usually '.gitignore') and allows such an untracked
but explicitly ignored file to be overwritten.
<tree-ish#>::
The id of the tree object(s) to be read/merged.
