NAME

chflags - change file flags

SYNOPSIS

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

DESCRIPTION

The chflags utility modifies the file flags of the listed files as specified 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.
