NAME
chflags —
change file flags
SYNOPSIS
chflags |
[-R [-H |
-L | -P]]
[-h] flags
file ... |
DESCRIPTION
Thechflags utility modifies the file flags of the
listed files as specified by the flags operand.
The options are as follows:
-H- If the
-Roption is specified, symbolic links on the command line are followed. (Symbolic links encountered in the tree traversal are not followed.) -h- If the file or a file encountered during directory traversal is a symbolic link, the file flags of the link itself is changed.
-L- If the
-Roption is specified, all symbolic links are followed. -P- If the
-Roption is specified, no symbolic links are followed. -R- Change the file flags for the file hierarchies rooted in the files instead of just the files themselves.
Flags are a comma separated list of keywords. The following keywords are currently defined:
| Keyword | Flag | Permission |
| arch | archived | super-user only |
| opaque | opaque | owner or super-user |
| nodump | nodump | owner or super-user |
| sappnd | system append-only | super-user only |
| schg | system immutable | super-user only |
| uappnd | user append-only | owner or super-user |
| uchg | user immutable | owner or super-user |
Putting the letters “no” before an option causes the flag to be turned off. For example:
- nouchg
- the immutable bit should be cleared
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
specified. The default is as if the -P option had
been specified.
The -o option of
ls(1)
is used to display the flags.
The kernel does not allow the flags on block and character devices to be changed except by the super-user.
EXIT STATUS
The chflags utility exits 0 on
success, and >0 if an error occurs.
