Is Bash more commonly used in security work than PowerShell? If so, why? (Now that Powershell can be used on Linux)

I tried to Google around for an answer on this, and the only questions we seem to have here are quite different, e.g.:

What should I learn for Cyber securityhttps://stackoverflow.com/questions/573623/is-powershell-ready-to-replace-my-cygwin-shell-on-windows

I know this is dangerously close to "opinion based", but this question has concrete answers in other areas - for example Kali over Windows / other Linux implementations for OS, Python over C#/Java in terms of the most common languages for security, etc.

  • Why is Powershell not popular on Linux? Because I snickered when you told me it was now available on Linux... Yeah, that's not going to catch on...

    The answer is simple: you use the tool that does what you need. Learn the tool that you like better, if both are equal. All questions here of the type "which should I learn, X or Y?" are the same: make a utilitarian choice based on your context. We can't tell you what you should do because we don't know (and can't know) all of your context.

  • My answer to these questions is always the same, and basically the same as what schroeder said: it doesn't really matter where you start your infosec journey; if you pick a technology (any technology) and learn it deeply enough to understand its security, then you're well on your way to being a security professional. Are there linux shops that need bash security experts? Yes. Are there Windows shops that need PS security experts? Yes. Are there more linux shops than Windows shops? Does it matter? Are you planning to work for all of them?

Is Bash more commonly used in security work than PowerShell?

Yes. For example, github appears to have more Security sh/bash scripts than it has ps1 scripts:

Search TermHits
github security sh14,100,000
github security bash9,110,000
github security ps1635,000

If so, why? (Now that Powershell can be used on Linux)

Rome wasn't built in a day. People have been writing sh and sh-compatible scripts on Unix and Linux for 40 years. Powershell may now be available on Linux, but it will still take quite some time for adoption to spread.
