  I thought it would be that as well, but in fact test seems to be happy with no
spaces around the square brackets.  I think it may be only if you want to use
the implicit form of test that the brackets need to be separated with spaces
from the test inside them, so that bash spots them as a separate token.

dk AT mace /tmp/bgcc> if [-dc:/baar]; then FRED=yes; else FRED=no; fi
bash: [-dc:/baar]: No such file or directory
dk AT mace /tmp/bgcc> if [ -dc:/baar ]; then FRED=yes; else FRED=no; fi
dk AT mace /tmp/bgcc> if test [-dc:/baar]; then FRED=yes; else FRED=no; fi
dk AT mace /tmp/bgcc>

  Yep, that looks fairly conclusive to me.

    cheers,
