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.
-R Change the file flags for the file hierarchies rooted in the
files instead of just the files themselves.
Flags are a comma separated list of keywords. The following keywords are
currently defined:
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
Symbolic links do not have flags, so unless the -H or -L option is set,
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 addi‐
tion, these options override each other and the command's actions are
determined by the last one specified.
The chflags utility exits 0 on success, and >0 if an error occurs.
