spdk VS shellharden

https://spdk.io will require you to load linux onto the server (livecd off a usb should be fine), but is essentially the most efficient way possible to do IO. Intel’s storage division used to use it to get the numbers they advertised with. When they loaded up a system with kioxia drives, Intel managed to hit 120 million IOPS in some of their testing.

Since the project I work on (https://spdk.io) largely produces a set of executables as output, it was most natural to write the tests in bash. There's one top level bash script that kicks off the full suite of tests and thousands and thousands of lines of tests all written as bash scripts stringing together calls to these executables.

One of these tests is to run shellcheck against all of the scripts in the repo. We don't allow any modifications to scripts without shellcheck giving them the green light now. The quality of our tests has increased dramatically since this was instituted - it's a really great tool.

FYI SPDK doesn't strictly require the IOMMU be enabled. See https://spdk.io/doc/system_configuration.html There's also a new experimental interrupt mode (not for everything) finding some valuable use cases in SPDK, see https://github.com/spdk/spdk/blob/master/CHANGELOG.md and feel free to jump on the SPDK slack channel or email list for more info on either of these https://spdk.io/community/

Everytime I see Shellcheck coming up, I have to mention shellharden[0] written by a colleague of mine. It is basically shellcheck but it applies the suggested changes automatically.

There is shellcheck, and shellharden which is a strict version of it. There are similar stuff here, some that also help with your editor. You can also use a docker version of shfmt. See here for a quick tutorial on shfmt.

Regarding linters, there are several of them in most languages.For bash, there is Shellcheck or a more strict (and sometimes confusing) Shellharden to do exactly what you want.

For example, shellharden looks awesome.
