How to recover keys

Run a command in background, but get a non-zero exit code *immediately* when `No such file or directory`
cn flag

I need to run some (unknown) command in the background like this:

nohup some_command &

Since such a command will run and (hopefully) complete in background, I cannot get its exit status immediately; that is OK.

However, I need to get an "error" exit status immediately in case that some_command is not found (i.e., when the error message from bash is No such file or directory or command not fo ...

sudo su not working as it should. Any ideas?
jp flag

I have searched this page for a similar question but found none. I use ubuntu 20.0 on hp workstation. Anytime I use $sudo su and input the root password the system gets stuck. Although when I use $Ctrl+c it gives me the root privilege but also returns an error (see below). I'm guessing this has something to do with the system configuration.

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.
