NAME
       replcon - SELinux file context replacement tool

SYNOPSIS
       replcon NEW_CONTEXT DIR [OPTIONS] [EXPRESSION]

DESCRIPTION
       replcon  allows  the  user  to find and replace file contexts.  Replacements 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 cir-
              cular 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 overrides -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 system 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 portion 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 contexts from the filesystem.

EXAMPLES
       replcon ::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.
