chflags -- change file flags
chflags [-R [-H | -L | -P]] [-d] [-h] flags file ...
The chflags utility modifies the file flags of the listed files as speci- fied by the flags operand. The options are as follows: -d If the change requested would not alter the flags currently set for file then attempt no change operation. -H If the -R option 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 are changed. -L If the -R option is specified, all symbolic links are fol- lowed. -P If the -R option is specified, no symbolic links are fol- lowed. -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 a keyword causes the flag to be turned off. For example, nouchg requests 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. Note that the ability to clear certain flags is dependent on the current kernel securelevel. See secmodel_securelevel(9) for details.
The chflags utility exits 0 on success, and >0 if an error occurs.
