Ubuntu doesn't seem to recognize my USB Drive as a boot option
id flag

I installed Ubuntu a month ago, but it isn't for me. I'm wanting to install Manjaro, but the problem is my system won't recognize it, despite me using BalenaEtcher to put the Manjaro ISO on it. Anyone know how to fix this?

Searching for and deleting files with a certain extension or ending with a number

Now I'd also like to have my script remove any file ending with a number regardless of the extension, as well as the files ending with the extension.

I tried the following commands with no success:

Problems with test signal into right speaker

I am running Ubuntu 20.04 and listen to quite a bit of music on my Companion II Series 3 Bose speakers. I noticed some pitches were absent on a few songs - but both speakers appear to be emitting sound okay - and in stereo; however when I run the speaker test under settings only the left speaker seems to give a signal.

These speakers have worked properly previously. I've played around with Alsami ...

How to only remove duplicate lines if they're immediately after each other in the file
in flag
Cas

Lets say I have the following file:

$ cat test.txt
a
-----
b
-----
-----
c
-----
-----
-----
d
-----
e
-----
-----

Now I want to remove all the -----, but only if they're repeating after each other. So the result should look like this:

a
-----
b
-----
c
-----
d
-----
e
-----

I tried grep -Pvz -- "-----\n-----", but that didn't work.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
