SYNOPSIS

       0store add DIGEST ARCHIVE [ EXTRACT ]

       0store audit [ DIRECTORY ... ]

       0store copy DIRECTORY [ DIRECTORY ]

       0store find DIGEST

       0store list

       0store manifest DIRECTORY [ ALGORITHM ]

       0store optimise [ CACHE ]

       0store verify ( DIGEST | DIRECTORY )

       0store manage

DESCRIPTION

       0store   provides  access  to  the  low-level  implementation  cache.  Normally,  the  cache  is  updated
       automatically using 0launch(1).

ADD

       To add a directory to the store (makes a copy):

       0store add sha256=XXX directory

       To add an archive to the store:

       0store add sha256=XXX archive.tgz

       To add a subdirectory of an archive to the store:

       0store add sha256=XXX archive.tgz subdir

       The actual digest is calculated and compared to the given one. If they  don't  match,  the  operation  is
       rejected.

AUDIT

       Verifies  every  implementation  in  each  of the given cache directories, or in all of the default cache
       directories if no arguments are given. This will detect any packages which have been tampered with  since
       they  were  unpacked.  If  0store itself could have been modified by an attacker, mount the suspect file-
       system on a known-good machine and run that machine's 0store on the mounted cache directory.

       See the "verify" command below for details of the verification performed on each package.

COPY

       To copy an implementation (a directory with a name in the form "algorithm=value"), use the copy function.
       This is similar to performing a normal recursive directory copy followed by a 0store verify to check that
       the name matches the contents. E.g.:

       0store                   copy                    ~someuser/.cache/0install.net/implementations/sha256=XXX
       /var/cache/0install.net/implementations/

FIND

       To find the path of a stored item:

       0store find sha256=XXX

LIST

       See the list of implementation caches currently configured:

       0store list

       To add directories to this list, add them to your 'implementation-dirs' configuration file.

MANAGE

       To open a window showing the contents of the cache:

       0store manage

       You  can  use  this  to  delete versions of programs you no longer need. However, this doesn't remove any
       launchers you added (trying to launch the program will prompt you to download the missing  files  again).
       For that, try:

       0desktop

MANIFEST

       Deprecated. Use "0install digest" instead.

OPTIMISE

       To hard-link duplicate files together to save space:

       0store optimise [CACHE]

       This  reads  in  all  the manifest files in the cache directory (~/.cache/0install.net/implementations by
       default) and looks for duplicates (files with the same permissions, modification time and digest).   When
       it finds a pair, it deletes one and replaces it (atomically) with a hard-link to the other.

       Implementations using the old 'sha1' algorithm are not optimised.

VERIFY

       To check that an item is stored correctly:

       0store verify /path/to/sha256=XXX

       This calculates the manifest of the directory and checks that its digest matches the directory's name. It
       also checks that it matches the digest of the .manifest file  inside  the  directory.  If  the  .manifest
       doesn't correspond to the current tree, it displays a list of the differences (in unified diff format).

COMMAND-LINE OPTIONS

       -h, --help
              Show the built-in help text.

       -v, --verbose
              More verbose output. Use twice for even more verbose output.

       -V, --version
              Display version information.

FILES

       ~/.cache/0install.net/implementations
              Cached implementations, indexed by manifest digest.

       ~/.config/0install.net/injector/implementation-dirs
              List of system cache directories, one per line.
