replcon(1)replcon(1)NAMEreplcon - SELinux file context replacement tool
SYNOPSISreplcon NEW_CONTEXT DIR [OPTIONS] [EXPRESSION]
DESCRIPTIONreplcon allows the user to find and replace file contexts. Replace‐
ments can be filtered by object class as described below.
REQUIRED ARGUMENTS
NEW_CONTEXT
The replacement context as expressed as a partial context,
described below.
DIR Initial directory to begin searching. The tool will recurse
into any subdirectories, so be sure there are no circular mounts
within it.
EXPRESSION
The following options allow the user to specify which files to find. A
file must meet all specified criteria for its context to be replaced.
If no expression is provided, all files' contexts are replaced.
-t TYPE, --type=TYPE
Search for files with a context containing the type TYPE.
-u USER, --user=USER
Search for files with a context containing the user USER.
-r ROLE, --role=ROLE
Search for files with a context containing the role ROLE.
-m RANGE, --mls-range=RANGE
Search for files with a context with the MLS range of RANGE.
Note that replcon ignores the SELinux translation library, if
present. In addition, this flag is ignored if DIR has no MLS
information.
--context=CONTEXT
Search for files matching this partial context. This flag over‐
rides -t, -u, -r, and -m.
-p PATH, --path=PATH
Search for files which include PATH.
-c CLASS, --class=CLASS
Search only files of object class CLASS.
OPTIONS-v, --verbose
Display context info during replacement.
-h, --help
Print help information and exit.
-V, --version
Print version information and exit.
PARTIAL CONTEXT
The --context flag and NEW_CONTEXT argument specify a partial context,
which is a a colon separated list of user, role, and type. If the sys‐
tem supports MLS, the context may have a fourth field that gives the
range. With --context if a field is not specified or is the literal
asterisk, then the query will always match the field. With NEW_CONTEXT
if a field is not specified or is the literal asterisk, then that por‐
tion of the context will not be modified.
OBJECT CLASSES
Valid object class strings are
block, char, dir, fifo, file, link, or sock.
NOTE
The replcon utility always operates on "raw" SELinux file contexts. If
the system has an installed translation library (i.e., libsetrans),
those translations are ignored in favor of reading the original con‐
texts from the filesystem.
EXAMPLESreplcon ::type_t: .
Replace every context's type in the current directory with
type_t. The user and role portion remain unchanged.
replcon-u user_u *:role_r:* .
Replace every context's role with user user_u in the current
directory with role_r. The user and type portion remain
unchanged.
replcon--context ::type_t:s0 :::s0:c0 /tmp
Replace every context with type type_t and MLS range s0 in /tmp
with MLS range s0:c0.
