Addition, multiplication, and apostrophe used to represent boolean algebra expressions?

I’m looking at a worksheet that expresses boolean logic expressions using multiplication, addition, and apostrophes; something I’ve never seen before.

I can make a guess that the apostrophe is equivalent to ¬ (except it’s suffixed instead of prefixed). But I’m not sure what the addition and multiplication of the variables/propositional atoms would mean. Furthermore, I don’t know how a boolean logic formula can “output” something other than just a truth value…

I can’t seem to piece together with certainty the meaning of this representation. Could anyone take a look at the below example and maybe make a guess as to a translation of this representation to the more traditional ^, v, and ¬ symbols?

This arose in the context of digital logic in terms of logic gates and such on a CPU, if that makes a difference.

syntax for creating variable out of command with apostrophe in it

NOOB level: horrible at syntax and regular expressions and BASH programming in general but learning and studying for the Lin+

I’d like to run this script but it doesn’t like my syntax apparently.

Just to test that the variable is being created properly I am echoing the output, but later, the variable will be manipulated to determine which static IP file to be concatted into /etc/network/interfaces and which list of network host IPs to scan with NMAP, grab logs from, etc.

here is the script:

#!/bin/bash # Script to grab the System IP and Gateway Addresses and use them to # determine which other scripts to run my network scans with  ip=$  (ip a | grep 'global[ \t]' | awk '{print $  2}') gateway=$  ('route -n | grep 'UG[ \t]' | awk '{print $  2}')  echo $  ip echo $  gateway  done 

Here is the output:

 ./test: 11: ./test: Syntax error: Unterminated quoted string 

When I put “” in place of () like this:

ip=$  "ip a | grep 'global[ \t]' | awk '{print $  2}'" gateway=$  "'route -n | grep 'UG[ \t]' | awk '{print $  2}'" 

Here is the output:

$  ip a | grep 'global[   ]' | awk '{print }' $  'route -n | grep 'UG[  ]' | awk '{print }' 

If i remove the $ the output is the same. It just prints the apostrophed command and doesn’t output the result of said command.

What am I doing wrong?

How to SUMIFS text beginning with apostrophe

I am receiving a list of products from an external data source. One of the the product names begins with an apostrophe. When I attempt to produce a summary of the products and total quantity using UNIQUE() and SUMIFS() the formula is returning zero for the product that begins with an apostrophe.

I have made an example sheet here:

https://docs.google.com/spreadsheets/d/191bqjUPPPtt5ZKeTw7pUplsve-tBdDBhpBV0Ic3e-nA/edit?usp=sharing

Interestingly, a VLOOKUP will work fine, but that will miss additional entries in the list.

Does anyone have any ideas on how to solve this without removing the leading apostrophe?

Apostrophe is HTML encoded in SharePoint List Item display form

In my SharePoint site I have list items with special characters in values. In the edit form and list views characters are rendered correctly. However in display form – “Apostrophe” (‘) is HTML encoded with ampersand.

The current encoding is UTF-8 for the site.

What could be the reason for this issue?

Apostrophe only appearing when the next key is pressed (Windows 10 1809)

Note: This is not a duplicate question. The previous solutions either don’t work or aren’t applicable due to the change in the options

As the title states, ‘ only appears after pressing the next key. If I press a character like ‘a’ after that, I get this – á (same with `. Instead I get à)

What’s the current solution? I have tried changing the language input but it didn’t work

Google Sheets Formula for Proper Case with Apostrophe

I’m using a Google Docs spreadsheet glued together (not be me) from multiple sources where some of the names are in all caps. In trying to clean web ready content, I have good success with the proper(#ref) function except when it is a name with an apostrophe.

If the cell contains SMITTY'S running it through the proper() function returns Smitty'S and is ugly. Any clever ideas around this?
