Is it possible to emulate (is that the right word?) previous versions of Bash?
I am using 4.3.11, and I am curious to know if my scripts are compatible with some earlier versions, but I don't want to actually install an earlier version. I could dig through the changelogs and figure out what features I'm using that are lacking from previous versions, but that seems a bit tedious. I was hoping for some kind of magical command line option insteador script command, instead (wishful thinking, probably).
