CHFLAGS(1)              NetBSD General Commands Manual              CHFLAGS(1)

     chflags - change file flags

     chflags [-R [-H | -L | -P]] [-h] 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:

     -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.)

     -L      If the -R option is specified, all symbolic links are followed.

     -P      If the -R option is specified, no symbolic links are followed.

     -R      Change the file flags for the file hierarchies rooted in the
             files instead of just the files themselves.

     -h      If the file or a file encountered during directory traversal is a
             symbolic link, the file flags of the link itself is changed.

     Flags are a comma separated list of keywords.  The following keywords are
     currently defined:
           arch    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  set the system append-only flag (super-user only)
           schg    set the system immutable flag (super-user only)
           uappnd  set the user append-only flag (owner or super-user only)
           uchg    set the user immutable flag (owner or super-user only)

     Putting the letters ``no'' before an option causes the flag to be turned
     off.  For example:
           nouchg  the immutable bit should be cleared

     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 specified.

     The -o option of ls(1) is used to display the flags.

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

     The kernel does not allow the flags on block and character devices to be
     changed except by the super-user.
