Command-line interface

Zero Install command-lines begin with 0install.
On Windows you can also use 0install-win instead. This will display outputs using windows instead of the console.

Command	Description
select	Selects a version of the program identified by URI, and compatible versions of all of its dependencies. Returns an exit status of 0 if it selected a set of versions, and a status of 1 if it could not find a consistent set.
download	Behaves similarly to 0install select, except that it also downloads the selected versions if they are not already cached. Returns an exit status of 0 if it selected a suitable set of versions and they are now all downloaded and in the cache; returns a status of 1 otherwise.
update	Checks for updates to the program and download them if found. This is similar to 0install download --refresh, except that it prints information about whether any changes were found.
run	Behaves similarly to 0install download, except that it also runs the program after ensuring it is in the cache. Returns an exit status of 1 if the download step failed. Otherwise, the exit status will be the exit status of the program being run.
import	Imports a feed from a local file, as if it had been downloaded from the network. This is useful when testing a feed file, to avoid uploading it to a remote server in order to download it again. The file must have a trusted digital signature, as when fetching from the network.
export (Windows only)	Exports all feeds and implementations required to launch the program specified by a URI to a DIRECTORY.
search	Searches for feeds indexed by the mirror server that match specified keywords. Note that the default mirror server indexes all known feeds, regardless of quality; you must decide whether to trust the programs before running them.
list	Lists all locally known feed URIs. If a search term is given, only URIs containing that string are shown (case insensitive).
catalog search (Windows only)	Searches registered catalogs for applications that match the specified query. If no query is given all applications in the catalogs are listed.
catalog refresh (Windows only)	Refreshes (downloads) all registered catalogs.
catalog add (Windows only)	Adds an URI to the list of catalogs.
catalog remove (Windows only)	Removes an URI from the list of catalogs.
catalog reset (Windows only)	Resets the list of catalogs to the default source.
catalog list (Windows only)	Lists all registered catalogs.
config	View or change configuration settings. With no arguments, it displays all settings and their current values. With one argument, it displays the current value of the named setting. With two arguments, it sets the setting to the given value or resets it to the default value if the value default is given.
trust add (Windows only)	Trusts feeds from a specific `DOMAIN` when [signed](../specifications/feed.md#digital-signatures) with a specific `FINGERPRINT`.
trust remove (Windows only)	Stops trusting feeds [signed](../specifications/feed.md#digital-signatures) with a specific `FINGERPRINT`. Only stops trusting for a specific `DOMAIN`, if specified.
trust list (Windows only)	List keys trusted for [signing](../specifications/feed.md#digital-signatures) feeds. Only list domains for which a specific `FINGERPRINT` is trusted, if specified.
add-feed	Register an additional source of implementations (versions) of a program.
remove-feed	Un-registers a feed, reversing the effect of 0install add-feed.
list-feeds	Lists all extra feeds added to URI using 0install add-feed.
digest	Calculates the manifest digest of a directory or archive.
store add	Adds the contents of a directory or archive to the cache.
store audit	Checks that all implementations in the cache are undamaged. Additional arguments specify custom cache locations.
store copy	Copies an implementation into the cache. Similar to 0install store add, but the digest is extracted from the directory name. An additional arguments specifies a custom target cache location.

store find	Determines the local path of a cached implementation.
store list	Lists all implementation cache directories.

store optimise	Saves disk space by merging identical files with hardlinks. Additional arguments specify custom cache locations.
store purge (Windows only)	Removes all implementations from the cache. Use this command to clean up the system before removing Zero Install. Deleting cache directories manually may be difficult due to the NTFS ACLs employed to protect implementations against modification. Additional arguments specify custom cache locations.
store remove	Removes an implementation from the cache.
