[править] NAME

    chflags -- change file flags

[править] SYNOPSIS

    chflags [-fhv] [-R [-H | -L | -P]] flags file ...


    The chflags utility modifies the file flags of the listed files as speci-
    fied by the flags operand.
    The options are as follows:
    -f      Do not display a diagnostic message if chflags could not modify
            the flags for file, nor modify the exit status to reflect such
    -H      If the -R option is specified, symbolic links on the command line
            are followed.  (Symbolic links encountered in the tree traversal
            are not followed.)
    -h      If the file is a symbolic link, change the file flags of the link
            itself rather than the file to which it points.
    -L      If the -R option is specified, all symbolic links are followed.
    -P      If the -R option is specified, no symbolic links are followed.
            This is the default.
    -R      Change the file flags for the file hierarchies rooted in the
            files instead of just the files themselves.
    -v      Cause chflags to be verbose, showing filenames as the flags are
            modified.  If the -v option is specified more than once, the old
            and new flags of the file will also be printed, in octal nota-
    The flags are specified as an octal number or a comma separated list of
    keywords.  The following keywords are currently defined:
          arch, archived
                  set the archived flag (super-user only)
          opaque  set the opaque flag (owner or super-user only)
          nodump  set the nodump flag (owner or super-user only)
          sappnd, sappend
                  set the system append-only flag (super-user only)
          schg, schange, simmutable
                  set the system immutable flag (super-user only)
          sunlnk, sunlink
                  set the system undeletable flag (super-user only)
          uappnd, uappend
                  set the user append-only flag (owner or super-user only)
          uchg, uchange, uimmutable
                  set the user immutable flag (owner or super-user only)
          uunlnk, uunlink
                  set the user undeletable flag (owner or super-user only)
    Putting the letters ``no before or removing the letters ``no from a
    keyword causes the flag to be cleared.  For example:
          nouchg  clear the user immutable flag (owner or super-user only)
          dump    clear the nodump flag (owner or super-user only)
    A few of the octal values include:
          0   Clear all file flags.
          1   Translates to the nodump keyword.
          2   Translates to the uchg keyword.
          3   Translates to the uchg, nodump keywords.
          4   Translates to the uappnd keyword.
          10  Translates to the opaque keyword.
          20  translates to the uunlnk keyword.
    Other combinations of keywords may be placed by using the octets
    assigned; however, these are the most notable.
    Unless the -H, -L, or -h options are given, chflags on a symbolic link
    always succeeds and has no effect.  The -H, -L and -P options are ignored
    unless the -R option is specified.  In addition, these options override
    each other and the command's actions are determined by the last one spec-
    You can use "ls -lo" to see the flags of existing files.
    Note that the ability to change certain flags is dependent on the current
    kernel securelevel setting.  See security(7) for more information on this

[править] EXIT STATUS

    The chflags utility exits 0 on success, and >0 if an error occurs.

[править] HISTORY

    The chflags command first appeared in 4.4BSD.

[править] BUGS

    Only a limited number of utilities are chflags aware.  Some of these
    tools include ls(1), cp(1), find(1), install(1), dump(8), and restore(8).
    In particular a tool which is not currently chflags aware is the pax(1)
