Is there a good reference about the differences between bourne shell and bash you could provide?

not really, I typically test with "dash" and use "checkbashisms" (packaged in factory and others) for clues on what goes wrong.

How can I test changes easily? Do we have some small shell being compatible to bourne shell but not compatible to bash, which would be recommended for testing? Apparently using "#!/bin/sh" doesn't do the job.

simply install "dash" and run the script with "dash" for local verification. (or busybox-sh if you want, which is the actual target)

For now its a correctness problem, but there's a project where we need a very minimal system, so busybox-sh will be /bin/sh (and there won't be a bin/bash). for openSUSE nothing is planned as far as I can say. while dash is faster in startup (and I happen to like the package maintainer), I am not planning to push it as default shell. -- You are receiving this mail because: You are on the CC list for the bug.

But maybe it is supported in all shells that can provide /bin/sh.

Its fine to depend on bash for now, don't worry about it. if it becomes a problem we can look at making the script posix sh compatible.

Is there any document, which shell features can be used with #!/bin/sh?

Well, the answer is the POSIX:2008 or SUS specification ;) I find https://mywiki.wooledge.org/Bashism a good reference as well as the "checkbashism" utility. -- You are receiving this mail because: You are on the CC list for the bug.
