CHFLAGS(1) FreeBSD General Commands Manual CHFLAGS(1)
chflags -- change file flags
chflags [-fhv] [-R [-H | -L | -P]] 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:
-f Do not display a diagnostic message if chflags could not modify the flags for file, nor modify the exit status to reflect such failures.
-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.)
-h If the file is a symbolic link, change the file flags of the link itself rather than the file to which it points.
-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.
-v Cause chflags to be verbose, showing filenames as the flags are modified. If the -v option is specified more than once, the old and new flags of the file will also be printed, in octal nota- tion.
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)
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)
sunlnk, sunlink set the system undeletable 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)
uunlnk, uunlink set the user undeletable flag (owner or super-user only)
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)
A few of the octal values include:
0 Clear all file flags.
1 Translates to the nodump keyword.
2 Translates to the uchg keyword.
3 Translates to the uchg, nodump keywords.
4 Translates to the uappnd keyword.
10 Translates to the opaque keyword.
20 translates to the uunlnk keyword.
Other combinations of keywords may be placed by using the octets assigned; however, these are the most notable.
Unless the -H, -L, or -h 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 spec- ified.
You can use "ls -lo" to see the flags of existing files.
Note that the ability to change certain flags is dependent on the current kernel securelevel setting. See security(7) for more information on this setting.
[править] EXIT STATUS
The chflags utility exits 0 on success, and >0 if an error occurs.
[править] SEE ALSO
The chflags command first appeared in 4.4BSD.
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.
