man chflags
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) |
