¿more vs less? ¿ifconfig vs ip? RTFM :)

Sigo sin entender por que muchos sitios en sus ejemplos usan MORE y IFCONFIG todavía. Jóvenes usen  LESS y IP de ahora en adelante.

man more
 NAME
 more - file perusal filter for crt viewing
SYNOPSIS
 more [options] file [...]
DESCRIPTION
 more is a filter for paging through text one screenful at a time. This version is especially primitive. Users should realize that less(1) provides more(1) emulation plus
 extensive enhancements.

man ifconfig
NAME
       ifconfig - configure a network interface

SYNOPSIS
       ifconfig [-v] [-a] [-s] [interface]
       ifconfig [-v] interface [aftype] options | address ...

NOTE
       This program is obsolete!  For replacement check ip addr and ip link.  For statistics use ip -s link.
