NAME
appstreamcli - Handle AppStream metadata and the AppStream index
SYNOPSIS
appstreamcli [COMMAND]
DESCRIPTION
This manual page documents briefly the appstreamcli command.
appstreamcli is a small helper tool to work with AppStream metadata and access the AppStream component
index from the command-line. The AppStream component index contains a list of all available software
components for your distribution, matched to their package names. It is generated using AppStream XML or
Debian DEP-11 data, which is provided by your distributor.
For more information about the AppStream project and the other components which are part of it, take a
look at the AppStream pages at Freedesktop.org[1].
OPTIONS
status
Display various information about the installed metadata and the metadata cache.
get ID
Get a component by it's identifier.
s, search TERM
Search the AppStream component database for a given search term.
what-provides TYPE TERM
Return components which provide a given item. An item type can be specified using the TYPE parameter,
a value to search for has to be supplied using the TERM parameter.
Examples:
Get components which handle the "text/xml" mimetype.
appstreamcli what-provides mimetype "text/xml"
Get component which provides the "libfoo.so.2" library.
appstreamcli what-provides lib libfoo.so.2
refresh, refresh-cache
Trigger a database refresh, if necessary. In case you want to force the database to be rebuilt,
supply the --force flag.
This command must be executed with root permission.
dump ID
Dump the XML description of a component with the given ID.
validate FILES
Validate AppStream XML metadata for compliance with the specification.
Both XML metadata types, upstream and distro XML, are handled. The filetype which should be validated
is determined automatically.
The --pedantic flag triggers a more pedantic validation of the file, including minor and style issues
in the report.
validate-tree DIRECTORY
Validate AppStream XML metadata found in a file-tree.
This performs a standard validation of all found metadata, but also checks for additional errors,
like the presence of .desktop files and validity of other additional metadata.
install ID
Install a software component by its ID.
This resolves the AppStream component ID to the package name which provides it and then calls the
distribution's package manager to install the software.
This feature is experimental.
put FILE
Install a metadata file into the right directory on the current machine.
new-template TYPE FILE
Create a metainfo file template to be used by software projects. The --from-desktop option can be
used to use a .desktop file as template for generating the example file.
The generated files contain example entries which need to be filed in with the actual desired values
by the project author.
The first TYPE parameter is the name of an AppStream component type. For a complete list check out
the documentation[2] or the help output of appstreamcli for this subcommand.
--details
Print out more information about a found component.
--no-color
Don't print colored output.
--no-net
Do not access the network when validating metadata.
The same effect can be achieved by setting the AS_VALIDATE_NONET environment variable before running
appstreamcli.
--version
Display the version number of appstreamcli
