0store(1) manage the implementation cache

NAME 0store — manage the implementation cache SYNOPSIS 0store add DIGEST DIRECTORY 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.
