Another “since forever” thing that is commented out on my system.
There are others too, like cp, ls, and df (the cp one is permissable, along with ‘colors’)
#alias cp="cp -i" # confirm before overwriting something
#alias df='df -h' # human-readable sizes
#alias free='free -m' # show sizes in MB
#alias np='nano -w PKGBUILD'
#alias more=less
(Check out that more one … its even an executable in /usr/bin/more that is provided by util-linux package, and it is being aliased to less, an entirely different utility …)
