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

       -R, --regex
              Enable regular expressions

       -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.
