Using bashisms in scripts does however cause a problem. I think it's time to realize that "bash" specifies a programming language, and so does "dash". Instead of focusing and hammering again and again on /bin/sh, why not instead ask maintainers to do #!/bin/dash? > Oh, and there *are* other suitable interactive shells than bash. tcsh, > ksh, zsh, rc...

I said that dash was not a substitute for bash, by its own claim. This is like a game of whackamole. If the claim is made that dash involves less disk space or memory use, it's nearly irrelevant, because bash will be there anyway. There may well be advantages to dash for this or that application. So then, maintainers should be encouraged to use it. The best way, of course, is #!/bin/dash. Thomas
