If the "no-owner" user has write access to the file they could copy the file to a new file name(thus getting ownership of the file), and overwriting the original file with the new file. e.g. [natea at us-cfe002:~]$ ls -l hosts -rw-r--r-- 1 root root 50 May 12 12:17 hosts [natea at us-cfe002:~]$ cp hosts hosts_new [natea at us-cfe002:~]$ ls -l hosts_new -rw-r--r-- 1 natea natea 50 May 12 12:18 hosts_new [natea at us-cfe002:~]$ mv hosts_new hosts mv: overwrite `hosts', overriding mode 0644? y [natea at us-cfe002:~]$ ls -l hosts -rw-r--r-- 1 natea natea 50 May 12 12:18 hosts [natea at us-cfe002:~]$ nate
