chflags
CHFLAGS(1) BSD General Commands Manual CHFLAGS(1) NAME
chflags -- change file flags SYNOPSIS
chflags [-R [-H | -L | -P]] [-h] flags file ... DESCRIPTION
The chflags utility modifies the file flags of the listed files as specified by the flags operand. The options are as follows: -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.) -L If the -R option is specified, all symbolic links are followed. -P If the -R option 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. -h If the file or a file encountered during directory traversal is a symbolic link, the file flags of the link itself is changed. 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 -o option of ls(1) is used to display the flags. The chflags utility exits 0 on success, and >0 if an error occurs. The kernel does not allow the flags on block and character devices to be changed except by the super-user. SEE ALSO
