DESCRIPTION

32       0store provides access to the low-level implementation cache. Normally,
33       the cache is updated automatically using 0launch(1).
34
35

ADD

37       To add a directory to the store (makes a copy):
38
39       0store add sha256=XXX directory
40
41
42       To add an archive to the store:
43
44       0store add sha256=XXX archive.tgz
45
46
47       To add a subdirectory of an archive to the store:
48
49       0store add sha256=XXX archive.tgz subdir
50
51
52       The actual digest is calculated and compared to the given one. If  they
53       don't match, the operation is rejected.
54
55

AUDIT

57       Verifies  every  implementation in each of the given cache directories,
58       or in all of the default cache directories if no arguments  are  given.
59       This  will detect any packages which have been tampered with since they
60       were unpacked.  If  0store  itself  could  have  been  modified  by  an
61       attacker, mount the suspect file-system on a known-good machine and run
62       that machine's 0store on the mounted cache directory.
63
64
65       See the "verify" command below for details  of  the  verification  per‐
66       formed on each package.
67
68

COPY

70       To  copy  an implementation (a directory with a name in the form "algo‐
71       rithm=value"), use the copy function. This is similar to  performing  a
72       normal  recursive  directory  copy followed by a 0store verify to check
73       that the name matches the contents. E.g.:
74
75       0store  copy   ~someuser/.cache/0install.net/implementations/sha256=XXX
76       /var/cache/0install.net/implementations/
77
78

FIND

80       To find the path of a stored item:
81
82       0store find sha256=XXX
83
84

LIST

86       See the list of implementation caches currently configured:
87
88       0store list
89
90       To add directories to this list, add them to your 'implementation-dirs'
91       configuration file.
92
93

MANAGE

95       To open a window showing the contents of the cache:
96
97       0store manage
98
99       You can use this to delete versions of programs  you  no  longer  need.
100       However,  this doesn't remove any launchers you added (trying to launch
101       the program will prompt you to download the missing files  again).  For
102       that, try:
103
104       0desktop
105
106

MANIFEST

108       Deprecated. Use "0install digest" instead.
109
110

OPTIMISE

112       To hard-link duplicate files together to save space:
113
114       0store optimise [CACHE]
115
116
117       This   reads   in  all  the  manifest  files  in  the  cache  directory
118       (~/.cache/0install.net/implementations by default) and looks for dupli‐
119       cates  (files with the same permissions, modification time and digest).
120       When it finds a pair, it deletes one and replaces it (atomically)  with
121       a hard-link to the other.
122
123
124       Implementations using the old 'sha1' algorithm are not optimised.
125
126

VERIFY

128       To check that an item is stored correctly:
129
130       0store verify /path/to/sha256=XXX
131
132       This  calculates  the  manifest  of  the  directory and checks that its
133       digest matches the directory's name. It also checks that it matches the
134       digest  of  the  .manifest  file inside the directory. If the .manifest
135       doesn't correspond to the current tree, it displays a list of the  dif‐
136       ferences (in unified diff format).
