tag is a command line tool to manipulate tags on Mac OS X 10.9 Mavericks files, and to query for files with those tags. tag can use the file system's built-in metadata search functionality to rapidly find all files that have been tagged with a given set of tags.
tag - A tool for manipulating and querying file tags.
usage:
tag -a | --add <tags> <file>... Add tags to file
tag -r | --remove <tags> <file>... Remove tags from file
tag -s | --set <tags> <file>... Set tags on file
tag -m | --match <tags> <file>... Display files with matching tags
tag -l | --list <file>... List the tags on file
tag -f | --find <tags> Find all files with tags
<tags> is a comma-separated list of tag names; use * to match/find any tag.
additional options:
-v | --version Display version
-h | --help Display this help
-n | --name Turn on filename display in output (default)
-N | --no-name Turn off filename display in output (list, find, match)
-t | --tags Turn on tags display in output (find, match)
-T | --no-tags Turn off tags display in output (list)
-g | --garrulous Display tags each on own line (list, find, match)
-G | --no-garrulous Display tags comma-separated after filename (default)
-H | --home Find tagged files only in user home directory
-L | --local Find tagged files only in home + local filesystems (default)
-R | --network Find tagged files in home + local + network filesystems
-0 | --nul Terminate lines with NUL (\0) for use with xargs -0
The add operation adds one or more tags to the specified files without modifying any tags already there.
tag --add tagname file
tag --add tagname1,tagname2,... file1 file2...
The remove operation removes one or more tags from the specified files.
tag --remove tagname file
tag --remove tagname1,tagname2,... file1 file2...
To remove all tags from a file, use the wildcard * to match all tags:
tag --remove \* file
The set operation replaces all tags on the specified files with one or more new tags.
tag --set tagname file
tag --set tagname1,tagname2,... file1 file2...
The match operation prints the file names that match the specified tags. Matched files must have at least all of the tags specified. Note that match matches only against the files that are provided as parameters. To search for tagged files across your filesystem, see the find operation.
tag --match tagname file
tag --match tagname1,tagname2,... file1 file2...
You can use a wildcard (*) character in the tags list to match against any/all tags. Note, however, that you'll need to quote that * against shell expansion. To display all files in the current directory that have any combination of tags (but not no tags), use:
tag --match \* *
Turn on --tags display mode for this operation to additionally show the tags on the file:
tag --match \* --tags *
Turn on garrulous output to format those tags onto multiple lines:
tag --match \* --tags --garrulous *
You may use short options as well. The following is equivalent to the previous command:
tag -tgm \* *
This list operation lists all the tags for each file specified.
tag --list file
tag --list file1 file2...
list is the default operation, so you may omit the list option:
tag file1 file2...
You can turn on garrulous mode for list as well:
tag -g *
If you just want to see tags, but not filenames, turn off display of files:
tag --no-name *
The find operation searches across your filesystem for all files that contain the specified tags. This uses the same filesystem metadata database that Spotlight uses, so it is fast.
tag --find tagname
tag --find tagname1,tagname2...
You can use the wildcard here too to find all files that contain a tag of any name:
tag --find \*
And of course you could turn on display of tag names, and even ask it to be garrulous, which displays all files on your system with tags, listing the tags independently on lines below the file names.
tag -tgf \*
find will by default find files within the user home directory + the local filesystem: the local scope. You may limit the scope to find only within the user home directory, or expand it to include mounted network filesystems.
tag --find tagname --home
tag --find tagname --local
tag --find tagname --network
Search scopes are additive; searching in network will also search local and home, etc.
The --help option will show you the command synopsis:
tag --help
You may install tag using the following package managers:
sudo port install tag
brew install tag
You must have Xcode or the Command Line Tools installed to build/install.
To build without installing:
make
This will build tag into ./bin/tag
To build and install onto your system:
make && sudo make install
This will install tag at /usr/local/bin/tag
Hints:
- Wherever a "tagname" is expected, a list of tags may be provided. They must be comma-separated.
- Tagnames may include spaces, but the entire tag list must be provided as one parameter: "a multiword tag name".
- Wherever a "file" is expected, a list of files may be used instead. These are provided as separate parameters.
- Note that directories can be tagged as well, so directories may be specified instead of files.
- The operation selector --add, --remove, --set, --match, --list, or --find may be abbreviated as -a, -r, -s, -m, -l, or -f, respectively. All of the options have a short version, in fact. See see the synopsis above, or output from help.
- If no operation selector is given, the operation will default to list.
- For compatibility with Finder, tags are compared in a case-insensitive manner.
- If you plan to pipe the output of tag through xargs, you might want to use the -0 option of each.
