As someone who sits more on the Ops side of DevOps in his current day job, developers who can say "df said the disk is full", "when I try to connect to it, it times out while connecting and we don't even get a syn/ack back, but it works fine from my phone", etc... I want to hug them. Additionally, I came across this comment the other day while debugging a firewall issue:

     // FIXME, we probably want to make this more robust since if it fails on startup it will never be good until we restart.

I was pretty upset to discover that the things I had been trying were all pointless, since I wasn't restarting the server every time, but that single line comment was the enlightenment I needed to solve the problem.

> Particularly the additional language - I'm sure most web software companies would rather a candidate knew more about the main languages used to build web things (HTML, CSS, JS, [Node|Ruby|PHP], and SQL) than something 'extra' that they're unlikely to use if only one dev knows it.

I think knowing things outside of just the web languages is the difference between someone who has pigeonholed themselves as a "web developer" vs. the more general "developer". Going for questionable analogies, I'd way rather have a "mechanic" than a "car mechanic" ("Oh? That's a 1/4 ton truck? Sorry, I only work on cars")

Ditto on the problem reporting being so much more useful coming from someone who knows how to do just a little bit of investigation and diagnostics.

A web developer who knows to try the issue from a different machine and a different network is so much more useful to those around them. Makes work much more smooth, and speeds up development too.

In a choice between two candidates for a web dev role it's going to come down to who's shows more interest in (say) CSS layout technologies or writing webpack plugins than any amount of UNIX knowledge. There's a minimum amount they'd need to know like navigating around a CLI and using NPM, but I certainly wouldn't expect a developer have any sort of sysadmin skillset.

I'm not suggesting it's bad to know them or that they're not nice things for a developer to have, just that I don't think they have any significant impact on the chances of getting hired.
