Ah. I don't remember if I was using csh, or ksh, and didn't realize about bash. I *think* I vaguely remember that sh seemed to be more capable than I remembered.
If you like to check what the Bourne Shell did support in the late 1980s, I recommend you to fetch recent Schily tools from:
https://sourceforge.net/projects/schilytools/files/
compile and install and test "osh".
This is the SVr4 Bourne Shell, so you need to take into account what has been added with Svr4:
- multibyte character support. In the 1980s, the Bourne Shell was just 8-bit clean.
- job-control. If you do not call "jsh", or if you switch off jobcontrol via "set +m" in a job shell, you have the job-control related builtins but there is no processgroup management.
