The "Write" permission (edit: on the directory).

w for others allows "others" to write to the file.
w for others set for the directory allows delete.

You probably just want world ("others") read. Assuming you want everybody to read a given file.

Not that I can see. This changes the way I look at UNIX file permissions a bit.

intersting. so having a folder with these permissions:
drwxr-x---

No one (except root and the owner) is allowed to delete a file inside that folder. Right?

Even those users who belong to the group cannot delete files because 'w' on the folder is only affected to the user.

Please let me know if what I am saying is true.

thx

Correct. Who the files belong to seems to be irrelevant, only the directory bits are considered when deleting; even a file owned by root, set to 000, can be deleted if I own the directory and have write access, or am in a group with write access.
