.Dd May 14, 2005 .Dt CHFLAGS 1 .Os .Sh NAME .Nm chflags .Nd change file flags .Sh SYNOPSIS .Nm .Op Fl h .Oo .Fl R .Op Fl H | Fl L | Fl P .Oc .Ar flags .Ar .Sh DESCRIPTION The .Nm 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 indent 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 h If the .Ar file is a symbolic link, change the mode of the link itself rather than the file to which it points. 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. This is the default. t Fl R Change the file flags for the file hierarchies rooted in the files instead of just the files themselves. .El
p The flags are specified as an octal number or a comma separated list of keywords. The following keywords are currently defined:
p l -tag -offset indent -width ".Ar opaque" t Ar arch , archived set the archived flag (super-user only) t Ar opaque set the opaque flag (owner or super-user only) t Ar nodump set the nodump flag (owner or super-user only) t Ar sappnd , sappend set the system append-only flag (super-user only) t Ar schg , schange , simmutable set the system immutable flag (super-user only) t Ar sunlnk , sunlink set the system undeletable flag (super-user only) t Ar uappnd , uappend set the user append-only flag (owner or super-user only) t Ar uchg , uchange , uimmutable set the user immutable flag (owner or super-user only) t Ar uunlnk , uunlink set the user undeletable flag (owner or super-user only) .El
p Putting the letters .Dq Ar no before or removing the letters .Dq Ar no from a keyword causes the flag to be cleared. For example:
p l -tag -offset indent -width "nouchg" -compact t Ar nouchg clear the user immutable flag (owner or super-user only) t Ar dump clear the nodump flag (owner or super-user only) .El
p Unless the .Fl H , .Fl L , or .Fl h options are given, .Nm 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. .Sh EXIT STATUS .Ex -std .Sh SEE ALSO .Xr ls 1 , .Xr chflags 2 , .Xr stat 2 , .Xr fts 3 , .Xr symlink 7 .Sh HISTORY The .Nm command first appeared in x 4.4 . .Sh BUGS Only a limited number of utilities are .Nm aware. Some of these tools include .Xr ls 1 , .Xr cp 1 , .Xr find 1 , .Xr install 1 , .Xr dump 8 , and .Xr restore 8 . In particular a tool which is not currently .Nm aware is the .Xr pax 1 utility.
