NAME

6       replcon - SELinux file context replacement tool
7

SYNOPSIS

9       replcon NEW_CONTEXT DIR [OPTIONS] [EXPRESSION]
10

DESCRIPTION

12       replcon  allows  the  user to find and replace file contexts.  Replace‐
13       ments can be filtered by object class as described below.
14

REQUIRED ARGUMENTS

16       NEW_CONTEXT
17              The replacement context  as  expressed  as  a  partial  context,
18              described below.
19
20       DIR    Initial  directory  to  begin  searching.  The tool will recurse
21              into any subdirectories, so be sure there are no circular mounts
22              within it.
23

EXPRESSION

25       The following options allow the user to specify which files to find.  A
26       file must meet all specified criteria for its context to  be  replaced.
27       If no expression is provided, all files' contexts are replaced.
28
29       -t TYPE, --type=TYPE
30              Search for files with a context containing the type TYPE.
31
32       -u USER, --user=USER
33              Search for files with a context containing the user USER.
34
35       -r ROLE, --role=ROLE
36              Search for files with a context containing the role ROLE.
37
38       -m RANGE, --mls-range=RANGE
39              Search  for  files  with  a context with the MLS range of RANGE.
40              Note that replcon ignores the SELinux  translation  library,  if
41              present.   In  addition,  this flag is ignored if DIR has no MLS
42              information.
43
44       --context=CONTEXT
45              Search for files matching this partial context.  This flag over‐
46              rides -t, -u, -r, and -m.
47
48       -p PATH, --path=PATH
49              Search for files which include PATH.
50
51       -c CLASS, --class=CLASS
52              Search only files of object class CLASS.
53

OPTIONS

55       -v, --verbose
56              Display context info during replacement.
57
58       -h, --help
59              Print help information and exit.
60
61       -V, --version
62              Print version information and exit.
63

PARTIAL CONTEXT

65       The  --context flag and NEW_CONTEXT argument specify a partial context,
66       which is a a colon separated list of user, role, and type.  If the sys‐
67       tem  supports  MLS,  the context may have a fourth field that gives the
68       range.  With --context if a field is not specified or  is  the  literal
69       asterisk, then the query will always match the field.  With NEW_CONTEXT
70       if a field is not specified or is the literal asterisk, then that  por‐
71       tion of the context will not be modified.
72

OBJECT CLASSES

74       Valid object class strings are
75
76       block, char, dir, fifo, file, link, or sock.
77

NOTE

79       The replcon utility always operates on "raw" SELinux file contexts.  If
80       the system has an installed  translation  library  (i.e.,  libsetrans),
81       those  translations  are  ignored in favor of reading the original con‐
82       texts from the filesystem.
83

EXAMPLES

85       replcon ::type_t: .
86              Replace every context's  type  in  the  current  directory  with
87              type_t.  The user and role portion remain unchanged.
88
89       replcon -u user_u *:role_r:* .
90              Replace  every  context's  role  with user user_u in the current
91              directory  with  role_r.   The  user  and  type  portion  remain
92              unchanged.
93
94       replcon --context ::type_t:s0 :::s0:c0 /tmp
95              Replace  every context with type type_t and MLS range s0 in /tmp
96              with MLS range s0:c0.
