为什么我不能删除php文件？

Question

我的服务器中有php文件。我试图删除它，但权限被拒绝。它是由php病毒创建的。

root @ host [/ home / depotdeb / public_html] #ls -la hl

Answer 1

根据这个：

d--------- 2 depotdeb depotdeb 4096 Jul 16 11:25 ./

您对文件所在的文件夹hl没有写入权限。试试这个：

cd /home/depotdeb/public_html
chmod 755 ./hl
#unset the immutable bit for the folder:
chattr -i ./hl
rm /home/depotdeb/public_html/hl/index.php
