Hi

thanks for the reply and solution... I want to ask you a question that *.bkp are directories and not files under /tftpboot directory. I am not sure if we can rotate directories using logrotate.

find /tftpboot/ -iname 'bkp*.gz' -type f -mtime +7 -exec rm -f \{\} \;

Also would you please explain what [ -exec rm -f \{\} \; ] means..
