darcs-all needs Bash but has #!/bin/sh

[Luke Maurer]

I get the following error trying to run ./darcs-all get --extra on Ubuntu Edgy:

luke@kryptonitespoon ghc $ ./darcs-all get --extra
[: 126: ==: unexpected operator
warning: adding --partial, to override use --complete
== running darcs get --partial --extra http://darcs.haskell.org/packages/base

darcs failed:  unrecognized option `--extra'

Note that the "unexpected operator" message always appears, with or without --extra. However, it appears that there's a processing loop that gets skipped because of the error, and so the --extra gets passed on to darcs.

If I change the shebang line to "#!/bin/bash", it works. My guess is that either the Bash-ism should be removed, or the shebang line should specify Bash.

It seems that there was a darcs patch for this very bug submitted by Alec Berryman two weeks ago:  http://www.haskell.org/pipermail/cvs-ghc/2007-March/034413.html but the patch doesn't seem to have been applied yet.

I've now applied the patch.

Thanks
