Hi,

First of all, you're making things too complicated. The
following would suffice:

AAA() {
     for i in $HOME/.wmii/*; do
         j=${i##*/}
         if wmiir ls /rbar/test-$j >/dev/null 2>&1; then
         # or:
        # wmiir ls /rbar | grep test-$j >/dev/null; then
             echo -n "$WMII_FOCUSCOLORS $j" | wmiir create /rbar/test-$j
             sleep 1
             wmiir remove /rbar/test-$j
         fi
     done
}

Second, your problem is that wmiirc disables globbing. This is
also the problem with your bbb script. You have the -f flag in
the shebang line when you run dash, but not bash. If you want it
to work, either add 'local set +f' to the function or ls the
directory rather than globbing its contents.

P.S. We use context (unified) diffs on this list.
