Command line tools like grep are force multipliers for programmers. GUI's come with the risk of not being able to learn how to leverage this power. In the end, that often leads to more manual work.
And today, bash is a lingua franca that you can bring with you almost everywhere. Even Windows "speaks" bash these days, with WSL.
In itself, there's nothing wrong with using the built-in features of a GUI. Right-clicking a method (or using a keyboard shortcut) to find the definition in a given code base IS nice for that particular operation.
But by knowing grep/awk/find/git command line and so on, combined with bash scripting and advanced regular expressions, you open up a new world of possibilities.
All those things CAN be done using Python/C#/Java or whatever your language is. But a 1-liner in bash can be 10-100 lines of C#.
Where does this stupid notion come from that using powerful tools means you can't handle the less powerful ones anymore? Did your skills with a hand screwdriver atrophy when you learned how to use a powered screwdriver? Come on.
I use grep multiple times a day. I write bash scripts quite often. I'm not speaking from a position of ignorance of these tools. They have their place as a lowest common denominator of programming tools. But settling for the lowest common denominator is not a path to productivity.
Doesn't mean you should forget your skills, but it does mean you should investigate better tools. And leverage them. A lot.

Yes. And the reverse is also true. bash is fast and easy if there's an existing tool you can leverage, and slow and hard when there's not.
Every person, including devlopers, have some constraints to what they're able to learn and use effectively. Those limits vary a lot from person to person, though.
For developers who learn technology a bit slowly (compared to some other developers, not the general population), some of these tools may not be worth the effort.
Also, these developers aren't necessarily low tier in terms of business value. They may have talents when it comes to understanding and communicating business requirements with other stakeholders in their organization, and their technical skills may be secondary to those skills and abilities.
BUT: For the general audience at HN, technical capability is central to their identity. Most people here have some capacity to learn technologies that go somewhat beyond the minimum skills required for a tech job. And for this audience, being confident on the linux/unix command line is generally worth the effort.
