When I try to do even the simplest rebase --interactive, I get a cryptic
error message:

$ git rebase -i HEAD~2
<do nothing in the editor that appears, just save>

I then get:

/usr/lib/git-core/git-rebase--interactive: 1: arithmetic expression:
expecting primary: "-c ^[^#]
2+-c ^[^#]
0"

and all I can do is git rebase --abort

Am I doing something wrong, or is this a bug? I am using git 1.6.4.2

thanks

Dave

It looks like something is going wrong with the 'grep -c' in
    mark_action_done () {
            sed -e 1q < "$TODO" >> "$DONE"
            sed -e 1d < "$TODO" >> "$TODO".new
            mv -f "$TODO".new "$TODO"
            count=$(grep -c '^[^#]' < "$DONE")
            total=$(($count+$(grep -c '^[^#]' < "$TODO")))
            if test "$last_count" != "$count"
            then
                    last_count=$count
                    printf "Rebasing (%d/%d)\r" $count $total
                    test -z "$VERBOSE" || echo
            fi
    }
are you using an unusual platform or have an unusual /bin/grep or
/bin/sh?

can you do before running the rebase (assuming a bourne shell) :

  unset GREP_OPTIONS

this looks like the bug I just send a patch to the list to fix and
which seems to be also reported in Ubuntu as :
