#!/bin/bash
# try to send 2 backslashes and Return (3 chars)
tst8="\\\\\\\\"
a="$(dash -c "echo \"$tst8\"" | wc -c)"
b="$(bash -c "echo \"$tst8\"" | wc -c)"
c="$(sh -c "/bin/echo \"$tst8\"" | wc -c)"

f="$(mksh -c "echo \"$tst8\"" | wc -c)"
g="$(busybox sh -c "echo \"$tst8\"" | wc -c)"
cat <<END
Results: (for shellia 3=OK)
dash:echo $a
bash:echo $b
/bin/echo $c
echo $d
posh:echo $e
mksh:echo $f
busybox:echo $g
END
[ "$(echo ":$a:$b:$c:$d:$e:$f:$g:" | grep ":2:")" ] && cat <<END
Warning:
the problem that backslashes are handled different
in some shells still exists.
Workaround:
shellia internally uses /bin/echo
