6 git-annex-unused - look for unused file content
7
9 git annex unused
10
12 Checks the annex for data that does not correspond to any files present
13 in any tag or branch, or in the git index, and prints a numbered list
14 of the data.
15
16 After running this command, you can use the --unused option with many
17 other git-annex commands to operate on all the unused data that was
18 found.
19
20 For example, to move all unused data to origin:
21
22 git annex unused; git annex move --unused --to origin
23
25 --fast
26
27 Only show unused temp and bad files.
28
29 --from=repository
30 Check for unused data that is located in a repository.
31
32 The repository should be specified using the name of a config‐
33 ured remote, or the UUID or description of a repository.
34
35 --used-refspec=+ref:-ref
36 By default, any data that the git index uses, or that any refs
37 in the git repository point to is considered to be used. If you
38 only want to use some refs, you can use this option to specify
39 the ones to use. Data that is not in the specified refs (and not
40 used by the index) will then be considered unused.
41
42 See REFSPEC FORMAT below for details of the format of this set‐
43 ting.
44
45 The git configuration annex.used-refspec can be used to config‐
46 ure this in a more permanent fashion.
47
48 --json Enable JSON output. This is intended to be parsed by programs
49 that use git-annex.
50
51 --json-error-messages
52 Messages that would normally be output to standard error are in‐
53 cluded in the JSON instead.
54
55 Also the git-annex-common-options(1) can be used.
56
58 The refspec format for --used-refspec and annex.used-refspec is a
59 colon-separated list of additions and removals of refs. A somewhat
60 contrived example:
61
62 +refs/heads/*:+HEAD^:+refs/tags/*:-refs/tags/old-tag:reflog
63
64 This adds all refs/heads/ refs, as well as the previous version of
65 HEAD. It also adds all tags, except for old-tag. And it adds all refs
66 from the reflog.
67
68 The default behavior is equivilant to --used-refspec=+refs/*:+HEAD
69
70 The refspec is processed by starting with an empty set of refs, and
71 walking the list in order from left to right.
72
73 Each + using a glob is matched against all relevant refs (a subset of
74 git show-ref) and all matching refs are added to the set. For example,
75 "+refs/remotes/*" adds all remote refs.
76
77 Each + without a glob adds the literal value to the set. For example,
78 "+HEAD^" adds "HEAD^".
79
80 Each - is matched against the set of refs accumulated so far. Any refs
81 with names that match are removed from the set.
82
83 "reflog" adds all the refs from the reflog. This will make past ver‐
84 sions of files not be considered to be unused until the ref expires
85 from the reflog (by default for 90 days). Note that this may make git-
86 annex unused take some time to complete, it if needs to check every ref
87 from the reflog.
