.SH NAME
chattr \- change file attributes on a Linux second extended file system
.SH SYNOPSIS
.B chattr

.I files...
.SH DESCRIPTION
.B chattr
changes the files attributes on an second extended file system.
.PP
The format of a symbolic mode is +-=[Scsu].
.PP
The operator `+' causes the selected attributes to be added to the
existing attributes of the files; `-' causes them to be removed; and
`=' causes them to be the only attributes that the files have.
.PP
The letters `Scsu' select the new attributes for the files: synchronous
updates (S), compressed (c), secure deletion (s), and undeletable (u).
.SH OPTIONS
.TP
.I -R
Recursively change attributes of directories and their contents.
.TP
.I -V
Verbosely describe changed attributes.
.TP
.I -v version
Set the files version.
.SH AUTHOR
.B chattr
has been written by Remy Card <card@masi.ibp.fr>, the developer and maintainer
of the ext2 fs.
.SH BUGS AND LIMITATIONS
As of ext2 fs 0.4, the kernel code only honours the `s' and `S' attributes. When
a file with the `s' attribute set is deleted, its blocks are zeroed and
written back to the disk. When a file with the `S' attribute set is modified,
the changes are written synchronously on the disk; this is equivalent to
the `sync' mount option applied to a subset of the files.
.PP
The other attributes will be implemented in a next ext2 fs version.
.SH AVAILABILITY
.B chattr
is available for anonymous ftp from ftp.ibp.fr (132.227.60.2) in
/pub/linux/BETA/ext2fs.
