git-annex-matching-options - specifying what to act on
Many git-annex commands support using these options to specify
which files they act on. Some of these options can also be used by commands
to specify which keys they act on.
Arbitrarily complicated expressions can be built using these
options. For example:
--include='*.mp3' --and -( --in=usbdrive --or --in=archive -)
The above example makes git-annex work on only mp3 files that are
present in either of two repositories.
- --exclude=glob
- Skips files matching the glob pattern. The glob is matched relative to the
current directory. For example:
-
git annex get --exclude='*.mp3' --exclude='subdir/*'
- Note that this will not match anything when using --all or --unused.
- --include=glob
- Skips files not matching the glob pattern. (Same as --not
--exclude.) For example, to include only mp3 and ogg files:
-
git annex get --include='*.mp3' --or --include='*.ogg'
- Note that this will not skip anything when using --all or --unused.
- --excludesamecontent=glob
- Skips a file when there is another file with the same content, whose name
matches the glob. The glob is matched relative to the current
directory.
- For example, to drop files in the archive directory, but not when the same
content is used by a file in the work directory:
-
git annex drop archive/ --excludesamecontent='work/*'
- --includesamecontent=glob
- Skips files when there is no other file with the same content whose name
matches the glob. (Same as --not --excludesamecontent)
- For example, if you have inbox and outbox directories, and want to find
anything in the inbox that has the same content as something in the
outbox:
-
git annex find inbox --includesamecontent='outbox/*'
- --in=repository
- Matches only when git-annex believes that the content is present in a
repository.
- The repository should be specified using the name of a configured remote,
or the UUID or description of a repository. For the current repository,
use --in=here
- Note that this does not check remote repositories to verify that content
is still present on them. However, when checking the current repository,
it does verify that content is present in it.
- --in=repository@{date}
- Matches only when the content was present in a repository on the given
date.
- The date is specified in the same syntax documented in gitrevisions(7).
Note that this uses the reflog, so dates far in the past cannot be
queried.
- For example, you might need to run git annex drop . to temporarily
free up disk space. The next day, you can get back the files you dropped
using git annex get . --in=here@{yesterday}
- --expected-present
- Matches only when git-annex believes that the content is present in the
local repository.
- This is like --in=here, except it does not verify that the content
is actually present. So it can be used in situations where the location
tracking information is known to be out of date.
- For example, if a repository is being restored from a backup that did not
include the git-annex objects, this could be used to get back all files
that were expected to be in it: git-annex get
--expected-present
- --copies=number
- Matches only when git-annex believes there are the specified number of
copies, or more. Note that it does not check remotes to verify that the
copies still exist.
- --copies=trustlevel:number
- Matches only when git-annex believes there are the specified number of
copies, on remotes with the specified trust level. For example,
--copies=trusted:2
- To match any trust level at or higher than a given level, use
'trustlevel+'. For example, --copies=semitrusted+:2
- --copies=groupname:number
- Matches only when git-annex believes there are the specified number of
copies, on remotes in the specified group. For example,
--copies=archive:2
- --lackingcopies=number
- Matches only when git-annex believes that the specified number or more
additional copies need to be made in order to satisfy numcopies
settings.
- --approxlackingcopies=number
- Like lackingcopies, but does not look at .gitattributes annex.numcopies
settings. This makes it significantly faster.
- --inbackend=name
- Matches only when content is stored using the specified key-value
backend.
- --securehash
- Matches only when content is hashed using a cryptographically secure
function.
- --inallgroup=groupname
- Matches only when git-annex believes content is present in all
repositories in the specified group.
- --onlyingroup=groupname
- Matches only when git-annex believes content is present in at least one
repository that is in the specified group, and is not present in any
repositories that are not in the specified group.
- --smallerthan=size
- --largerthan=size
- Matches only when the content is is smaller than, or larger than the
specified size.
- The size can be specified with any commonly used units, for example,
"0.5 gb" or "100 KiloBytes"
- --metadata
field=glob
- Matches only when there is a metadata field attached with a value that
matches the glob. The values of metadata fields are matched case
insensitively.
- --metadata
field<value / --metadata field>value
- --metadata
field<=value / --metadata field>=value
- Matches only when there is a metadata field attached with a value that is
less then or greater than the specified value, respectively.
- When both values are numbers, the comparison is done numerically. When one
value is not a number, the values are instead compared
lexicographically.
- (Note that you will need to quote the second parameter to avoid the shell
doing redirection.)
- --want-get
- Matches only when the preferred content settings for the local repository
make it want to get content. Note that this will match even when the
content is already present, unless limited with e.g., --not
--in=here
- --want-drop
- Matches only when the preferred content settings for the local repository
make it want to drop content. Note that this will match even when the
content is not present, unless limited with e.g., --not
--in=here
- Things that this matches will not necessarily be dropped by git-annex
drop --auto. This does not check that there are enough copies to drop.
Also the same content may be used by a file that is not wanted to be
dropped.
- --want-get-by=repository
- Matches only when the preferred content settings for the specified
repository make it want to get content. Note that this will match even
when the content is already present in that repository, unless limited
with e.g., --not --in=repository
- The repository should be specified using the name of a configured remote,
or the UUID or description of a repository. --want-get-by=here is
the same as --want-get.
- --want-drop-by=repository
- Matches only when the preferred content settings for the specificed
repository make it want to drop content. Note that this will match even
when the content is not present, unless limited with e.g., --not
--in=repository
- The repository should be specified using the name of a configured remote,
or the UUID or description of a repository. --want-drop-by=here is
the same as --want-drop.
- --accessedwithin=interval
- Matches when the content was accessed recently, within the specified time
interval.
- The interval can be in the form "5m" or "1h" or
"2d" or "1y", or a combination such as
"1h5m".
- So for example, --accessedwithin=1d matches when the content was
accessed within the past day.
- If the OS or filesystem does not support access times, this will not match
anything.
- --unlocked
- Matches annexed files that are unlocked.
- --locked
- Matches annexed files that are locked.
- --mimetype=glob
- Looks up the MIME type of a file, and checks if the glob matches it.
- For example, --mimetype="text/*" will match many
varieties of text files, including "text/plain", but also
"text/x-shellscript", "text/x-makefile", etc.
- The MIME types are the same that are displayed by running file
--mime-type
- If the file's annexed content is not present, the file will not
match.
- This is only available to use when git-annex was built with the MagicMime
build flag.
- --mimeencoding=glob
- Looks up the MIME encoding of a file, and checks if the glob matches
it.
- For example, --mimeencoding=binary will match many kinds of binary
files.
- The MIME encodings are the same that are displayed by running file
--mime-encoding
- If the file's annexed content is not present, the file will not
match.
- This is only available to use when git-annex was built with the MagicMime
build flag.
- --anything
- Always matches. One way this can be useful is git-annex find
--anything will list all annexed files, whether their content is
present or not.
- --nothing
- Never matches. (Same as --not --anything)
- --not
- Inverts the next matching option. For example, to match when there are
less than 3 copies, use --not --copies=3
- --and
- Requires that both the previous and the next matching option matches. The
default.
- --or
- Requires that either the previous, or the next matching option
matches.
- -(
- Opens a group of matching options.
- -)
- Closes a group of matching options.
