CHFLAGS(1) OpenBSD Reference 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 flags of a file dictate special restric- tions beyond those enforced by its mode/permissions. The options are as follows: -R Recursively descend through any specified directory arguments. Change the flags of the file hierarchies rooted in the files in- stead of just the files themselves. -H If the -R option is also 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 also specified, all symbolic links are fol- lowed. -P If the -R option is also specified, no symbolic links are fol- lowed. Flags are a comma separated list of keywords. The following keywords are currently defined: arch set the archived flag opaque set the opaque flag (owner or superuser only) nodump set the nodump flag (owner or superuser only) sappnd set the system append-only flag (superuser only) schg set the system immutable flag (superuser only) uappnd set the user append-only flag (owner or superuser only) uchg set the user immutable flag (owner or superuser only) An immutable file may not be changed, moved, or deleted. An append-only file is immutable except that data may be appended to it. Putting the letters ``no'' before a flag name causes the flag to be turned off. For example: nouchg the immutable bit should be cleared The superuser-settable ``sappnd'' and ``schg'' flags can be set at any time, but may only be cleared when the system is running at security lev- el 0 or -1 (insecure or permanently insecure mode, respectively). The securelevel is normally set to 0, for example, when running in single-us- er mode. 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 ad- dition, these options override each other and the command's actions are determined by the last one specified. Only the superuser can change the user flags on block and character de- vices. You can use ls -lo to see the flags of existing files. The chflags utility exits 0 on success or >0 if an error occurred. SEE ALSO ls(1), chflags(2), stat(2), fts(3), symlink(7) HISTORY The chflags command first appeared in 4.4BSD.
