As I posted on Wednesday  ....

grep -r HOSTNAME /etc/*

 gives rise to ....

 /etc/init.d/hostname.sh:        [ -f /etc/hostname ] && HOSTNAME="$(cat /etc/hostname)"
 /etc/init.d/hostname.sh:        [ -z "$HOSTNAME" ] && HOSTNAME="$(hostname)"
 /etc/init.d/hostname.sh:        [ -z "$HOSTNAME" ] && HOSTNAME=localhost
 /etc/init.d/hostname.sh:        [ "$VERBOSE" != no ] && log_action_begin_msg "Setting hostname to '$HOSTNAME'"
 
 on Debian stable.

If you grep -ir instead you'll automagically find both HOSTNAME and hostname as well as any case variation between.
