.Dd March 31, 1994 .Dt CHFLAGS 1 .Os .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.
p The options are as follows: l -tag -width Ds t 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.) t Fl L If the .Fl R option is specified, all symbolic links are followed. t Fl P If the .Fl R option is specified, no symbolic links are followed. t Fl R Change the file flags for the file hierarchies rooted in the files instead of just the files themselves. .El
p Flags are a comma separated list of keywords. The following keywords are currently defined: d -literal -offset indent compact arch set the archived flag (super-user only) dump set the dump flag sappnd set the system append-only flag (super-user only) schg set the system immutable flag (super-user only) sunlnk set the system undeletable 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) uunlnk set the user undeletable flag (owner or super-user only) archived, sappend, schange, simmutable, uappend, uchange, uimmutable, sunlink, uunlink aliases for the above .Ed
p Putting the letters .Dq no before an option causes the flag to be turned off. For example: d -literal -offset indent compact nodump the file should never be dumped .Ed
p 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.
p You can use "ls -lo" to see the flags of existing files.
p The .Nm chflags utility exits 0 on success, and >0 if an error occurs. .Sh SEE ALSO .Xr ls 1 , .Xr chflags 2 , .Xr stat 2 , .Xr fts 3 , .Xr symlink 7 .Sh HISTORY The .Nm chflags command first appeared in x 4.4 .
