A read from this file returns uncompressed data. A write to +this file compresses data before storing them on the disk. + +A file with the `d' attribute set is not candidate for backup when the +.BR dump (8) +program is run. + +A file with the `i' attribute cannot be modified: it cannot be deleted or +renamed, no link can be created to this file and no data can be written +to the file. Only the superuser can set or clear this attribute. + +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. + +When a file with the `u' attribute set is deleted, its contents is saved. +This allows the user to ask for its undeletion. +.SH AUTHOR +.B chattr +has been written by Remy Card , the developer and maintainer +of the ext2 fs. +.SH BUGS AND LIMITATIONS +As of ext2 fs 0.5a, the `c' and `u' attribute are not honoured by the kernel +code. +.PP +These attributes will be implemented in a future ext2 fs version. +.SH AVAILABILITY +.B chattr +is available for anonymous ftp from ftp.ibp.fr and tsx-11.mit.edu in +/pub/linux/packages/ext2fs. +.SH SEE ALSO +.BR lsattr (1) -- cgit v1.2.3
