The following information may help to resolve the situation:

cp

Copy file1 to file2 preserving the mode, ownership and timestamp.

  $ cp -p file1 file2

mv

Rename file1 to file2. if file2 exists prompt for confirmation before overwritting it.

  $ mv -i file1 file2

rm

get confirmation before removing the file.

  $ rm -i file*

cd

change directory.

  $ cd path

change back to previous directory

  $ cd -

pwd

Print working directory, shows the path of the current directory

  $ pwd

Book summary

The Automatic Millionaire starts with the powerful story of an average American couple—he’s a low-level manager, she’s a beautician—whose joint income never exceeds $55,000 a year, yet who somehow manage to own two homes debt-free, put two kids through college, and retire at 55 with more than $1 million in savings. Through their story you’ll learn the surprising fact that you cannot get rich with a budget! You have to have a plan to pay yourself first that is totally automatic, a plan that will automatically secure your future and pay for your present.
 
What makes The Automatic Millionaire unique:
 
·        You don’t need a budget
·        You don’t need willpower
·        You don’t need to make a lot of money
·        You don’t need to be that interested in money
·        You can set up the plan in an hour
 

by Joseph Malins (1895)

-a poem about prevention -

'Twas a dangerous cliff, as they freely confessed,

though to walk near its crest was so pleasant;

but over its terrible edge there had slipped

a duke and full many a peasant.

So the people said something would have to be done,

but their projects did not at all tally;

some said, 'Put a fence 'round the edge of the cliff, '

some, 'An ambulance down in the valley.'

But the cry for the ambulance carried the day,

for it spread through the neighboring city;

a fence may be useful or not, it is true,

but each heart became full of pity

for those who slipped over the dangerous cliff;

And the dwellers in highway and alley

gave pounds and gave pence, not to put up a fence,

but an ambulance down in the valley.

'For the cliff is all right, if your careful, ' they said,

'and if folks even slip and are dropping,

it isn't the slipping that hurts them so much

as the shock down below when they're stopping.'

So day after day, as these mishaps occurred,

quick forth would those rescuers sally

to pick up the victims who fell off the cliff,

with their ambulance down in the valley.

A brief, no fluff, summary of Dale Carnegie’s How to Win Friends and Influence People.

James Lawrence, best known as the “Iron Cowboy", was born in Calgary, Alberta, Canada. Married to Sunny who is the partner in their journey, is also a proud father of five wonderful kids: his daughters, Lucy, Lily, Daisy and Dolly, and his son, Quinn. On June 6, 2015, James attempted to complete 50 Ironman Triathlons in 50 consecutive days across all 50 U.S. States.

He trained knowing that he and his family would be moving from state to state and race to race in an RV, with little time to pick up or prepare meals along the way so he had to be sure his body was prepared to get through each race on “regular” food. He invited people in every state to join him on the last leg of the marathon, and most dinners and bike sandwiches were supplied by coordinators in each city. Lawrence didn’t have the luxury of relying on a highly specialized diet when so much of what he ate was out of his hands.

Hairpinning (or NAT loopback) is where a machine on the LAN is able to access another machine on the LAN via the external IP address of the LAN/router (with port forwarding set up on the router to direct requests to the appropriate machine on the LAN).
