He,

there is a bug in HUSH's handling of "if" / "elif" commands:

        $  if true
        > then
        > echo 1
        > elif
        > true
        > then
        > echo 2
        > elif
        > true
        > then
        > echo 3
        > else
        > echo 4
        > fi
        1
        2
        3
        $

The same bug exists in all versions of HUSH from BB v0.60.x up to and
including v1.00-pre9. The attached patch fixes this:

        $ if true
        > then
        > echo 1
        > elif
        > true
        > then
        > echo 2
        > elif
        > true
        > then
        > echo 3
        > else
        > echo 4
        > fi
        1
        $



Best regards,

Wolfgang Denk
