Chattr read-only file system

Can anyone please explain me about -e options in chattr. I am seeing like this ———————e— for the file. It indicates that the file is using extents for mapping the blocks on disk. Extents is file system dependent. It may not be removed using chattr. To know more about extent, see the wikipedia page for extent filesystem.

Thanks for you information on chattr command. There is one small modification in 4th point. You need to change the placements of the command..

Thank you for pointing this out. I needed chattr -ai to fix a directory that was mute. Appreciate it. Kyle: Thnx for pointing out… You are correct… Need to unchattr before changing their password.

Since I can't comment: chattr is most likely using one of chmod, fchmod or fchmodat syscalls, or ioctl which doesn't mention anything about symlinks.

From chmod man page: chmod never changes the permissions of symbolic links; the chmod system call cannot change their permissions. Nephilim Nephilim 39 4 4 bronze badges. Sorry, I missed the part where you mention ioctl ; but the references to fchmod etc.
