Hush does not handle "set -o pipefail".

[Christopher Barry]

I find this a fairly useful method in bash, if not perfect.

function pipe_status()
{
    local -a pipestatus=( ${@} )
    for ((p=0;p<${#pipestatus[@]};p++))
    do
        if [[ ${pipestatus[${p}]} -ne 0 ]]
        then
            echo "failure in pipe index ${p} (${pipestatus[${p}]})" >&2
            return ${pipestatus[${p}]}
        fi
    done
    return 0
}
#---------------------------------------------------------------------
do | a | really | long | pipe
pipe_status ${PIPESTATUS[@]} || handle_error ${?}


I don't use hush though, so no idea if this will work in that shell or
not.
