Operating Systems 1 Lab 5 - Shell Script Creation

Shell Script Creation

First I logged into Linnux, then I used the command echo and created the files ReallyImportantFile1 and ReallyImportantFile2. I then used the command ls so that I could see the files I had just created listed out on the screen.

Next I created a folder called BackUpFolder using the command mkdir. I then copied the contents of any files with the ending .txt into this file using the command cp *.txt, I then listed out the contents of this new folder I created.

I then used the command cat so that I could list out the file so I would be able to see the commands I had used.

I then needed to change the file to make it executable. I used the chmod command to achieve this. I then tried to use the command MakeABackup.sh but this didn't seem to do anything so I had to try a different command. I was succesful with ./MakeUpBackup.sh and I was able to get through.

Operating Systems 1 Lab 4 – DOS Batch File Creation

Really Important Program 1

I entered the text "This is a really important program" and saved it as "reallyimportantprogram1.txt". It was requested that this document and the following document "reallyimportantprogram2.txt" was created in order to be added to the Backup Folder later on.

                    Really Important Program 2

 I entered the text "This is a really important program" and saved it as "reallyimportantprogram2.txt". It was requested that this document and the following document "reallyimportantprogram1.txt" was created in order to be added to the Backup Folder later on.

                          Make A Backup File

I created the following document. Upon creating this document I observed that a new folder appeared in the same location I had saved my really important program text files, named "Backup Folder". 

Command Window

The command window output showed that the MakeABackup.bat when searched in the command window contained the contents of the 2 really important program text files within the newly created "Backup Folder".

Path

Operating Systems 1 Lab #1

RANKING	ITEM	REASON
#1	Two 110b tanks of oxygen	Without oxygen, you wouldn’t be alive in the first place, so any kind of travel would be out of the question!
#2	5 gallons of water	A 200mile trip would definitely require a well hydrated team to survive.
#3	Stellar map of the moons constellations	200miles in an unknown land would require a map, or else you’d have no idea where to go.
#4	A magnetic compass	To compliment the map, we need a compass to steer us in the right direction and pinpoint our location.
#5	Portable heating unit	We’ve potentially landed on the dark side of the moon, if we’ve missed the light side, this has potential to be incredibly chilly. To avoid hypothermia the team need a heat source.
#6	Food concentrate	Once we know where we’re going, we need sustenance to get us through the lengthy trip.
#7	Solar-power FM receiver-transmitter	In order to keep in touch with the crew and mothership, it’s important to have the transmitter.
#8	50’ nylon rope	The rope can be used to keep the crew together and pull along the life raft holding the rest of the items
#9	Life raft	We decided the life raft and parachute silk could be used to carry and tie down the smaller items for the trip to stop them floating away.
#10	Parachute silk	The parachute silk, as above, could be used to tie down the arbitrary items and stop them floating away.
#11	One case of dehydrated pet milk	This is further down the list as it sounds delightfully unappealing, if we’re in need of calcium we will access the dehydrated pet milk.
#12	Signal flares	There was uncertainty as to whether this was the special type of flare that can be used on the moon, so it’s in this place and will be used in the event of a missing crew member.
#13	First-aid kid containing injection needles	It was uncertain as to whether a crew mate could be accessed in the event of an injury or emergency, given that a puncture to the suit (with for example a needle) would probably kill them almost instantaneously.
#14	Two .45 calibre pistols	We were totally dumbfounded as to what the pistols could be used for… if there were potential moon martians to fight off? Given this uncertainty, it’s rather low in priorities.
#15	Box of matches	Given that the crew receive oxygen via the tanks, without oxygen in the atmosphere, I can’t see how the flame would even light - therefore these are small, useless fragments of wood.
