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 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 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 lit-
       eral 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.
