chflags(1) BSD General Commands Manual chflags(1)
NAME
chflags -- change file flags
SYNOPSIS
chflags [-R [-H | -L | -P]] flags file ...
DESCRIPTION
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. This is the default. -R Change the file flags for the file hierarchies rooted in the files instead of just the files themselves. 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). [Directory is opaque when viewed through a union mount] 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) 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) hidden set the hidden flag [Hide item from GUI] As discussed in chflags(2), the sappnd and schg flags may only be unset when the system is in single-user mode. 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) Unless the -H or -L 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 specified. You can use "ls -lO" to see the flags of existing files.
EXIT STATUS
The chflags utility exits 0 on success, and >0 if an error occurs.

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) utility. BSD May 14, 2005 BSD
