How does `ls` work?

I wanted to be really able to explain to a fair amount of detail how does the program :command:`ls` actually work right from the moment you type the command name and hit ENTER. What goes on in user space and and in kernel space? This is my attempt and what I have learned so far on Linux (Fedora 19, 3.x kernel).

How does the shell find the location of 'ls' ?

Make sure you've pulled the new upstream branch into your local repo:

First, ensure your working tree is clean (commit/stash/revert any changes) Then,

git fetch upstream

to retrieve the new upstream branch 2. Create and switch to a local version of the new upstream branch (newbranch):

docker image prune -f

docker rmi $(docker images -q)
docker rm -v $(docker ps -qa)

Python code

regions = [r['RegionName'] for r in boto3.client('ec2').describe_regions()['Regions']]

If jdeployer needs to be built. This happens when we want to incorporate new JD code.

cd Repos/atom/jdeployerSaaS
./jdeployer_image_builder.sh

Tag this new JD image

docker tag jdeployer:220422 svl-artifactory.juniper.net/atom-docker/atom-of/mukil/jdeployer:R1.2

Ubuntu

kubectl run my-shell --rm -it --restart=Never --image ubuntu -- bash

Netshoot

kubectl run tmp-shell --rm -it --image nicolaka/netshoot
