kandi X-RAY | ter Summary
ter is a cli to run text expressions and perform basic text operations such as filtering, ignoring and replacing on the command line. There are many great tools that do this job. But most other tools have one in common: They are hard to memorize if you dont use them regularly. ter tries to solve this issue by providing a super simple cli & expression language which can be easily memorized and is well documented.

QUESTION
Basically, I want to check if strings present in lookup_1 & lookup_2 exists in my xyz.txt file then perform action & redirect output to an output file. Also, my code is currently substituting all occurrences of the strings in lookup_1 even as substring, but I need it to only substitute if there's a whole word match. Can you please help in tweaking the code to achieve the same?

...ANSWER
Answered 2022-Apr-11 at 14:38We can make a couple changes to the current code:
- feed the results of
cat lookup_1 lookup_2
intoawk
such that it looks like a single file toawk
(see last line of new code) - use word boundary flags (
\<
and\>
) to build regexes with which to perform the replacements (see 2nd half of new code)
The new code:

I'm doing a vote counting system, the winner is the one who has more than 3 votes, however, I'm facing the following problem. When there is more than one place with 3 votes, instead of my JSON returning the one with the most votes, it always returns the one with more than 3 votes ordered by ID. That is, if the restaurant with ID 1 has 3 votes, and the restaurant with ID 2 has 10 votes, the restaurant with ID 1 ends up appearing on the route /restaurants/winner despite not being the most voted, is there any way I can make the most voted show up?
e.g: return from /restaurants/winner route

...ANSWER
Answered 2022-Jan-11 at 18:43Since you have modified it with onlyOwner, only the owner can call it. So
msg.sender
is actually owner
.
the owner should be payable. If there is no other bug in your code, this should solve it:
