better to print out '$8' also. It lists the year of installation (or, if a new installation, the time).

so this is cause the files in /etc and /bin /sbin are not usually modified after the first install. Is there a generic command for all disrtos cause i use rpm -qi basesystem on rpm based systems to get the install date cause the basesystem is the first package to be installed

yeah, this is supposed to work on all systems, since they all contain something like a Linux Standard Base /etc/lsb-* file or dir in /etc which isn't modified after install. In fedora's case you also have /etc/system-release

another way on a dpkg-based (debian/ubuntu) system is to look at the timestamps on the files in /var/lib/dpkg/info/ - they gives the times of each packaging system action.

Better to check /lost+found as it's generally less likely to have been recreated since installation...
