Comment (by knarf):

 We cannot rely on bash being the shell. What about the following, taken
 from

 http://www.unix.com/shell-programming-scripting/92163-command-does-not-
 return-exit-status-due-tee.html

 {{{
        You can use this function to make it easier:

        run() {
          j=1
          while eval "\${pipestatus_$j+:} false"; do
            unset pipestatus_$j
            j=$(($j+1))
          done
          j=1 com= k=1 l=
          for a; do
            if [ "x$a" = 'x|' ]; then
              com="$com { $l "'3>&-
                          echo "pipestatus_'$j'=$?" >&3
                        } 4>&- |'
              j=$(($j+1)) l=
            else
              l="$l \"\$$k\""
            fi
            k=$(($k+1))
          done
          com="$com $l"' 3>&- >&4 4>&-
                     echo "pipestatus_'$j'=$?"'
          exec 4>&1
          eval "$(exec 3>&1; eval "$com")"
          exec 4>&-
          j=1
          while eval "\${pipestatus_$j+:} false"; do
            eval "[ \$pipestatus_$j -eq 0 ]" || return 1
            j=$(($j+1))
          done
          return 0
        }

        use it as:

        run cmd1 \| cmd2 \| cmd3
        exit codes are in $pipestatus_1, $pipestatus_2, $pipestatus_3
