I find myself in a strange situation where a script wrote files with the following permissions:

-r-------- 1 user1 user1 file1 Dec 24 14:53
-r-------- 1 user1 user1 file2 Dec 24 14:54
-r-------- 1 user1 user1 file3 Dec 24 14:55

How do I remove these files? I can't change the permissions of the files with chmod [neither with 'user1' nor as sudo/root].

[If it makes any difference, I am running ubuntu]

Can you change the owner using chown username file? – Ali Hashemi Dec 24 '13 at 14:12
@Pazis No, I don't have permissions for that! It's a recursive problem :( – Dhara Dec 24 '13 at 14:16
I cannot see the problem: I can easily chmod my files, even when their permissions are just 400. And I can delete them. Your problem is elsewhere (disk mount, perhaps?). – MariusMatutiae Dec 24 '13 at 16:11
@MariusMatutiae - In your computer you will be the owner of the files so you won't find any problem in your system. – vishram0709 Dec 24 '13 at 17:01
Right. Are you telling me you are trying to erase someone else's files? – MariusMatutiae Dec 24 '13 at 17:01

Removing a file means changing the directory containing them. The file's permissions (and its ownership, for that matter) are inconsequential.

So, if you have write permissions to the containing directory, a simple rm should work.

If you do not, you will have to chmod +w . first.
