How do you write this Linux code?

rpartee1 · 03-26-2022, 07:14 PM

Question:
The Pointy Hair Manager wants to be double sure his double secret e-mail makes it to the appropriate person in the Department of Redundancy Department without being deciphered.
He wants you to encrypt it using your sed transform skills. So replace all letters, capital and lowercase and numbers with alternate characters. You'll need 62(IIRC) alternates and you can use fun stuff, remember to

escape (\) the really weird ones. You will need your script to output your encryption to a file.

The phm_double_secret.txt file is this:

To the Head of the Department of Redundnacy Department,

I believe that, with a bit of work, 33.33% of current system administration

staff, Bob, can be furloughed, saving approximately, oh, around $12,532.67

a year.

Please tell me the correct code in Linux? The phm_double_secret.txt file is this

This will bring my total cost savings proposal for the year up to four - the

point were my 25% bonus kicks in. Raising my salary by $72,000.53 a year.

Sincerely,

PHM

P.S. I do feel that I am underpaid - after all my staff works very hard!

Yet another homework question from the OP.

Except for you, since you just post your work here for us to do for you

Again, show your efforts.

just banish this freeloader [for ? a month / until they beg forgiveness and actually come clean about their inability to actually attempt to solve even the most trivial of 'challenges'

^^ Please, we can, and should be more welcoming that that! It can be difficult to phrase first questions in a new forum. Hopefully, if the OP continues their study they will find their own place among the crowd!

From my side I have only one question to the OP: what did you implement so far, where did you stuck, what is your actual problem?

Ok, I'll play.

Example:

Code:

text="The Pointy Hair Manager wants to be double sure his double secret  
e-mail makes it to the appropriate person in the Department of Redundancy  
Department without being deciphered."

base64 <<< "$text" > text2.txt

cat text2.txt
VGhlIFBvaW50eSBIYWlyIE1hbmFnZXIgd2FudHMgdG8gYmUgZG91YmxlIHN1cmUgaGlzIGRvdWJs
ZSBzZWNyZXQgIAplLW1haWwgbWFrZXMgaXQgdG8gdGhlIGFwcHJvcHJpYXRlIHBlcnNvbiBpbiB0
aGUgRGVwYXJ0bWVudCBvZiBSZWR1bmRhbmN5ICAKRGVwYXJ0bWVudCB3aXRob3V0IGJlaW5nIGRl
Y2lwaGVyZWQuCg==

base64 -d text2.txt
The Pointy Hair Manager wants to be double sure his double secret  
e-mail makes it to the appropriate person in the Department of Redundancy  
Department without being deciphered.

Authenticate:

Code:

base64 <<< $(echo abcdefg)
YWJjZGVmZwo=

auth.sh

Code:

#!/usr/bin/bash

#Correct answer is abcdefg
read -p "Type your secret code: " secr
scode=$(echo 'YWJjZGVmZwo=' | base64 --decode)

if [ $secr == $scode ]; then
    echo "You are authenticated"
else
    echo "You are not authenticated"
fi

Code:

bash ./auth.sh
Type your secret code: abcdefg
You are authenticated

bash ./auth.sh
Type your secret code: xyzabc
You are not authenticated

no echo and $() required

Code:

base64 <<< pleasure

Otherwise I like it.

Don't bother; OP has posted on a get-your-homework-done-for-you site:

I'm not really sure if it was the same person (or a classmate).
I definitely would not pay ($15) for a solution on that site.

Exact same wording, and email address starts with "rpartee1". Hard to imagine two people posting the exact same thing with the same words, and an almost identical user name.

Regardless, the OP hasn't responded to any of their threads, and until they do, there's little we can assist with.
