如何使用rm -rf从目录中删除文件？

Question

I have directory exam with 2 files in it. I need to delete files but permission is denied. Even ![rm -rf][1] command can't delete these files. I logged in as a root user.

# rm -rf exam_a
# rm -rf exam_b

Answer 1

From root user check attributes of files

# lsattr 

if you notice i or a

# man chattr
# chattr -i [filename]
# chattr -a [filename]

if it doesn't work reboot system.
