I am using dhclient on Debian (isc-dhcp-client, isc-dhcp-common).The logs that dhclient is logging are flooded with copyright information and other useless stuff (please consult README, please visit http://...)This is how simple dhcp session looks like:dhclient:  Internet Systems Consortium DHCP Client 4.2.2dhclient:  Copyright 2004-2011 Internet Systems Consortium.dhclient:  All rights reserved.dhclient:  For info, please visit https://www.isc.org/software/dhcp/dhclient:  dhclient:  Listening on LPF/wlan0/aa:bb:cc:dd:ee:ffdhclient:  Sending on   LPF/wlan0/aa:bb:cc:dd:ee:ffdhclient:  Sending on   Socket/fallbackdhclient:  DHCPRELEASE on wlan0 to 192.168.0.1 port 67dhclient:  send_packet: Network is unreachabledhclient:  send_packet: please consult README file regarding broadcast address.dhclient:  Internet Systems Consortium DHCP Client 4.2.2dhclient:  Copyright 2004-2011 Internet Systems Consortium.dhclient:  All rights reserved.dhclient:  For info, please visit https://www.isc.org/software/dhcp/dhclient:  dhclient:  Listening on LPF/wlan0/aa:bb:cc:dd:ee:ffdhclient:  Sending on   LPF/wlan0/aa:bb:cc:dd:ee:ffdhclient:  Sending on   Socket/fallbackdhclient:  DHCPRELEASE on wlan0 to 192.168.0.1 port 67dhclient:  send_packet: Network is unreachabledhclient:  send_packet: please consult README file regarding broadcast address.dhclient:  Internet Systems Consortium DHCP Client 4.2.2dhclient:  Copyright 2004-2011 Internet Systems Consortium.dhclient:  All rights reserved.dhclient:  For info, please visit https://www.isc.org/software/dhcp/dhclient:  dhclient:  Listening on LPF/wlan0/aa:bb:cc:dd:ee:ffdhclient:  Sending on   LPF/wlan0/aa:bb:cc:dd:ee:ffdhclient:  Sending on   Socket/fallbackdhclient:  DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 7dhclient:  DHCPREQUEST on wlan0 to 255.255.255.255 port 67dhclient:  DHCPOFFER from 192.168.0.1dhclient:  DHCPACK from 192.168.0.1dhclient:  bound to 192.168.0.16 -- renewal in 36865 seconds.The important information is mixed with garbage. This is an issue for me because I am forwarding important logs (including dhclient), and having them displayed in the background. And since dhclient often renews the lease, the log can get quite long pretty quickly. I then have to scroll up to see other logs.Is it possible to hide the garbage, and only keep the relevant information?
