I have a small text file that I want to ensure cannot be accidentally deleted, so I ran chattr -i /home/anne/WebPages/UserBase/filename.txt

(as root, of course). Running lsattr against the same file produced -------------e- /home/anne/WebPages/UserBase/filename.txt 'i' doesn't show in ls -l filename, either. I haven't come across 'e' before. What is it, and is my file immutable or not?

From chattr man page, the rule is: - sign removes, + sign adds = sign makes it the only attribute. You should type: chatttr +i /home/anne/etc.. then with lsattr you'll see something like: ----i-------- file.txt
