| 22 | .Sh DESCRIPTION | |
| 23 | The | |
| 24 | .Nm chflags | |
| 25 | utility modifies the file flags of the listed files | |
| 26 | as specified by the | |
| 27 | .Ar flags | |
| 28 | operand. | |
| 29 | .Pp | |
| 30 | The options are as follows: | |
| 31 | .Bl -tag -width Ds | |
| 74ee26c2 EA |
32 | .It Fl H |
| 33 | When encountering a symbolic link on the command line, follow it. All other | |
| 34 | symbolic links encountered in the traversal are not followed. | |
| dc986658 KM |
35 | .It Fl R |
| 36 | Traverse a file hierarchy. | |
| 37 | For each file that is of type directory, | |
| 38 | .Nm chflags | |
| 39 | changes the flags of all files in the file hierarchy below it followed | |
| 40 | by the flags of the directory itself. | |
| 74ee26c2 EA |
41 | .It Fl h |
| 42 | When encountering a symbolic link anywhere in the traversal, follow it. | |

45 | Flags are a comma separated list of keywords. |
| 46 | The following keywords are currently defined: | |
| 47 | .Bd -literal -offset indent compact | |
| 48 | .\"arch nothing yet. | |
| 49 | dump set the dump flag | |
| b0a4b439 KM |
50 | sappnd set the system append-only flag (super-user only) |
| 51 | schg set the system immutable flag (super-user only) | |
| 52 | uappnd set the user append-only flag (owner or super-user only) | |
| 53 | uchg set the user immutable flag (owner or super-user only) | |

| 55 | .Pp | |
| 56 | Putting the letters | |
| 57 | .Dq no | |
| 58 | before an option causes the flag to be turned off. | |
| 59 | For example: | |
| 60 | .Bd -literal -offset indent compact | |
| 61 | nodump the file should never be dumped | |
| 62 | .Ed | |

64 | The flags of a symbolic link are immutable, so that unless the |
| 65 | .Fl h | |
| 66 | or | |
| 67 | .Fl H | |
| 68 | flags are set, | |
| 69 | .Nm chflags | |
| 8a499f2f | 70 | on a symbolic link always succeeds and has no effect. |
| dc986658 KM |

| 72 | The | |
| 73 | .Nm chflags | |
| 74 | utility exits 0 on success, and >0 if an error occurs. | |
