Hi, I have a folder inside /var/www/cgi-bin which is own by a normal user, as follows: Under /var/www/
drwxr-xr-x 4 root daemon 512 Oct XX XX:XX cgi-bin/ Under /var/www/cgi-bin/ drwxr-xr-x 4 sg daemon 512 Oct XX XX:XX my-site/ Under /var/www/cgi-bin/my-site/ drwxrwxr-x 3 sg www 512 Oct XX XX:XX posts/ Under /var/www/cgi-bin/my-site/posts/ drwxrwxr-x 3 sg www 512 Oct XX XX:XX messages/ At /var/www/cgi-bin/my-site/posts/messages, I receive file texts send to the server via POST. Under /var/www/cgi-bin/my-site/posts/messages/ -rw-r--r-- 1 www www 6163795 Oct XX XX:XX OneFile.txt Then, when I execute the following command as unprivileged user sg: sg:/home/sg$mv /var/www/cgi-bin/my-site/posts/messages/*.txt /tmp I got the following error message: mv: /tmp/OneFile.txt: set owner/group: Operation not permitted However, it does actually move the file and change the permissions accordingly: Under /tmp -rw-r--r-- 1 sg wheel 6163795 Oct XX XX:XX OneFile.txt What just happend? // Carlos Aguilar
