We are tried to count how many files belong to certain group. Our system administrator told us "non-owner" can easy change file group name to another. I have been tried several combination and never successful (only ROOT can change file group to other name).
Does anyone know how "no-owner" can change file group name?
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@us-cfe002:~]$ ls -l hosts -rw-r--r-- 1 root root 50 May 12 12:17 hosts [natea@us-cfe002:~]$ cp hosts hosts_new [natea@us-cfe002:~]$ ls -l hosts_new -rw-r--r-- 1 natea natea 50 May 12 12:18 hosts_new [natea@us-cfe002:~]$ mv hosts_new hosts mv: overwrite `hosts', overriding mode 0644? y [natea@us-cfe002:~]$ ls -l hosts -rw-r--r-- 1 natea natea 50 May 12 12:18 hosts [natea@us-cfe002:~]$
