git-lfs-fetch(1) -- Download all Git LFS files for a given ref
==============================================================

## SYNOPSIS

`git lfs fetch` [options] [<remote> [<ref>...]]

## DESCRIPTION

Download Git LFS objects at the given refs from the specified remote. See
[DEFAULT REMOTE] and [DEFAULT REFS] for what happens if you don't specify.

This does not update the working copy.

## OPTIONS

* `-I` <paths> `--include=`<paths>:
  Specify lfs.fetchinclude just for this invocation; see [INCLUDE AND EXCLUDE]

* `-X` <paths> `--exclude=`<paths>:
  Specify lfs.fetchexclude just for this invocation; see [INCLUDE AND EXCLUDE]

* `--recent`:
  Download objects referenced by recent branches & commits in addition to those
  that would otherwise be downloaded. See [RECENT CHANGES]

* `--all`:
  Download all objects referenced by any commit that is reachable; this is
  primarily for backup / migration purposes. Cannot be combined with --recent or
  --include/--exclude. Ignores any globally configured include and exclude paths
  to ensure that all objects are downloaded.

* `--prune` `-p`:
  Prune old and unreferenced objects after fetching, equivalent to running
  `git lfs prune` afterwards. See git-lfs-prune(1) for more details.

## INCLUDE AND EXCLUDE

You can configure Git LFS to only fetch objects to satisfy references in certain
paths of the repo, and/or to exclude certain paths of the repo, to reduce the
time you spend downloading things you do not use.

In gitconfig, set lfs.fetchinclude and lfs.fetchexclude to comma-separated lists
of paths to include/exclude in the fetch (wildcard matching as per gitignore).
Only paths which are matched by fetchinclude and not matched by fetchexclude
will have objects fetched for them.

### Examples:

* `git config lfs.fetchinclude "textures,images/foo*"`

  This will only fetch objects referenced in paths in the textures folder, and
  files called foo* in the images folder

* `git config lfs.fetchinclude "*.jpg,*.png,*.tga"`

  Only fetch JPG/PNG/TGA files, wherever they are in the repository

* `git config lfs.fetchexclude "media/reallybigfiles"`

  Don't fetch any LFS objects referenced in the folder media/reallybigfiles, but
  fetch everything else

* `git config lfs.fetchinclude "media"`<br/>
  `git config lfs.fetchexclude "media/excessive"`

  Only fetch LFS objects in the 'media' folder, but exclude those in one of its
  subfolders.

## DEFAULT REMOTE

Without arguments, fetch downloads from the default remote.  The default remote 
is the same as for `git fetch`, i.e. based on the remote branch you're tracking 
first, or origin otherwise.

## DEFAULT REFS

If no refs are given as arguments, the currently checked out ref is used. In
addition, if enabled, recently changed refs and commits are also
included. See [RECENT CHANGES] for details.

## RECENT CHANGES

If the `--recent` option is specified, or if the gitconfig option
`lfs.fetchrecentalways` is true, then after the current ref (or those in the 
arguments) is fetched, we also search for 'recent' changes to fetch 
objects for, so that it's more convenient to checkout or diff those commits 
without incurring further downloads. 

What changes are considered 'recent' is based on a number of gitconfig options:

* `lfs.fetchrecentrefsdays`
  If non-zero, includes branches which have commits within N days of the current 
  date. Only local refs are included unless lfs.fetchrecentremoterefs is true.
  The default is 7 days.

* `lfs.fetchrecentremoterefs`
  If true, fetches remote refs (for the remote you're fetching) as well as local
  refs in the recent window. This is useful to fetch objects for remote branches 
  you might want to check out later. The default is true; if you set this to 
  false, fetching for those branches will only occur when you either check them 
  out (losing the advantage of fetch --recent), or create a tracking local 
  branch separately then fetch again.

* `lfs.fetchrecentcommitsdays`
  In addition to fetching at branches, also fetches changes made within N 
  days of the latest commit on the branch. This is useful if you're often 
  reviewing recent changes. The default is 0 (no previous changes).

* `lfs.fetchrecentalways`
  Always operate as if --recent was provided on the command line.
  

## EXAMPLES

* Fetch the LFS objects for the current ref from default remote

  `git lfs fetch`

* Fetch the LFS objects for the current ref AND recent changes from default 
  remote

  `git lfs fetch --recent`

* Fetch the LFS objects for the current ref from a secondary remote 'upstream'

  `git lfs fetch upstream`

* Fetch the LFS objects for a branch from origin

  `git lfs fetch origin mybranch`

* Fetch the LFS objects for 2 branches and a commit from origin

  `git lfs fetch origin master mybranch e445b45c1c9c6282614f201b62778e4c0688b5c8`
