.Sh NAME | ||
.Nm chflags | ||
.Nd change file flags | ||
.Sh SYNOPSIS | ||
.Nm chflags | ||
.Oo | ||
.Fl R | ||
.Op Fl H | Fl L | Fl P | ||
.Oc | ||
.Ar flags | ||
.Ar file ... | ||
.Sh DESCRIPTION | ||
The | ||
.Nm chflags | ||
utility modifies the file flags of the listed files | ||
as specified by the | ||
.Ar flags | ||
operand. | ||
.Pp | ||
The options are as follows: | ||
.Bl -tag -width Ds | ||
.It Fl H | ||
If the | ||
.Fl R | ||
option is specified, symbolic links on the command line are followed. | ||
(Symbolic links encountered in the tree traversal are not followed.) | ||
.It Fl L | ||
If the | ||
.Fl R | ||
option is specified, all symbolic links are followed. | ||
.It Fl P | ||
If the | ||
.Fl R | ||
option is specified, no symbolic links are followed. | ||
.It Fl R | ||
Change the file flags for the file hierarchies rooted | ||
in the files instead of just the files themselves. | ||
.El | ||
.Pp | ||
Flags are a comma separated list of keywords. | ||
The following keywords are currently defined: | ||
.Bd -literal -offset indent compact | ||
.\"arch nothing yet. | ||
dump set the dump flag | ||
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) | ||
.Ed | ||
.Pp | ||
Putting the letters | ||
.Dq no | ||
before an option causes the flag to be turned off. | ||
For example: | ||
.Bd -literal -offset indent compact | ||
nodump the file should never be dumped | ||
.Ed | ||
.Pp | ||
Symbolic links do not have flags, so unless the | ||
.Fl H | ||
or | ||
.Fl L | ||
option is set, | ||
.Nm chflags | ||
on a symbolic link always succeeds and has no effect. | ||
The | ||
.Fl H , | ||
.Fl L | ||
and | ||
.Fl P | ||
options are ignored unless the | ||
.Fl R | ||
option is specified. | ||
In addition, these options override each other and the | ||
command's actions are determined by the last one specified. | ||
.Pp | ||
The | ||
.Nm chflags | ||
utility exits 0 on success, and >0 if an error occurs. | ||
.Sh SEE ALSO | ||
.Xr chflags 2 , | ||
.Xr stat 2 , | ||
.Xr fts 3 , | ||
.Xr symlink 7 |
