 There are a number of init systems used on docker containers, many are the defaults that ship with the standard Linux distributions, e.g. systemd which is particularly popular on the larger comprehensive distributions.\\   There are a number of init systems used on docker containers, many are the defaults that ship with the standard Linux distributions, e.g. systemd which is particularly popular on the larger comprehensive distributions.\\

 +=====alias in S6 init=====
 +I like the alias command to change some default CLI command flags, in particular ls => ls -la, which I normally call ll.  I had no success using the alias command in S6 init scripts. I found the following solution, by using the s6 pre_start_script to add a link ''ll.sh'' script in to the ''/bin'' directory.
 +
 +<code bash>#get my favourite alias working in Alpine sh has been a pain
 +/bin/ln -s /app/scripts/ll.sh /bin/ll</code>
 +
 +Where ''ll.sh'' is:
 +<code bash>#!/bin/sh
 +exec ls -la "$@"</code>
