> cross-platform automation > bash Nope. Show me the script that gets a list of mounted filesytems for locally attached disks and flags any that are larger than 20G and are more than 90% full. Since it is cross platform it will run the same on linux/bsd/os x and windows, right?

I haven't used the Windows Subsystem for Linux much, but shouldn't it be possible to have a bash script that runs on all of them? (though it might take some testing against the environment, for things like osx's /Volumes etc.)

  I use WSL daily, and yes you can see your entire C:\ drive in WSL under /mnt/c/, and all the common directory commands work, so running a bash script is 'cross-platform' in that way. That's sort of cheating though. In that instance, Bash isn't really being cross platform, so much as Windows bent over backwards to re-implement lots of Linux underneath Bash, so Bash could treat Linux and Linux (on Windows) identically. Or to restate that: If Linux apps get to claim they are 'cross-platform' because of WSL, then Windows apps get to claim they are 'cross-platform' because you could run them in WINE.

  Exactly.. It's sort of possible.. if nothing goes wrong and you remember to run df in posix mode and you manage to parse the output correctly.

Don't forget about AIX, Solaris, and IRIX :-)

  And HP-UX, Ultrix, Tru64, and probably a few more. https://en.wikipedia.org/wiki/HP-UX https://en.wikipedia.org/wiki/HP-UX I used HP-UX for a while; it was good. In fact I first wrote this Unix utility [1] (and later an IBM developerWorks article about it) on an HP-UX system, for a big manufacturing client. HP-UX was pretty stable and had a good patch management system. Had some good tools from HP on top of the OS, such as GlancePlus, Ignite-UX, Process Resource Manager, etc., and another high-end one called MC ServiceGuard. https://en.wikipedia.org/wiki/Ultrix https://en.wikipedia.org/wiki/Ultrix https://en.wikipedia.org/wiki/Tru64_UNIX https://en.wikipedia.org/wiki/Tru64_UNIX Edit: Sorry, forgot to add the link I quoted above. Done now: [1] https://jugad2.blogspot.in/2014/09/my-ibm-developerworks-article.html https://jugad2.blogspot.in/2014/09/my-ibm-developerworks-art... It's a tutorial on the topic: Developing a Linux command-line utility (in C).

    HP-UX is still alive until 2025 apparently. I used on my workstation for a while (an HP Visualize C3000) in the 90s -- it was my first 64-bit workstation. It's not great.

      Interesting. Haven't used it for a while. I miss that OS. Last used it some years ago, so things have moved on since then. For the time, I found it good, though. And HP had pretty good quality in those days - in both hardware and software (the stuff I used, anyway). Also, I only used it on HP business servers - the PA-RISC series, not on their workstations. Don't know, but there could be some differences in the HP-UX versions between the servers and workstations, the latter which, IIRC, were based on the acquisition of Apollo (but don't know much about that).

        The HP Visualize C3000 is a PA-RISC 2.0 system (2x 400MHz processors). I still build a cross-compiler toolchain for HP-UX PA-RISC 2.0 long-mode (64-bit address mode).
