a complex text in ksh

hello,

could someone please tell me, why the bracket [highlight #EF2929]}[/highlight] appears on the output?

$ ( echo A B C D ::;sed 's/\(.\{1\}\)/\1 /g' vvvv|sort|while read A B C D;do printf "$A $B $C $D :: "; [ $A -eq 1 -a $B -eq 1 -a $C -eq 1 -a $D -eq 1 ] && echo "errors: A and B and C and D" || { [ $A -eq 1 -a $B -eq 0 -a $C -eq 0 -a $D -eq 0 ] && echo "errors: A" || { [ $A -eq 1 -a $B -eq 1 -a $C -eq 0 -a $D -eq 0 ] && echo "errors: A and B" || { [ $A -eq 1 -a $B -eq 1 -a $C -eq 1 -a $D -eq 0 ] && echo "errors: A and B and C" || { [ $A -eq 1 -a $B -eq 1 -a $C -eq 0 -a $D -eq 1 ] && echo "errors: A and B and D" || { [ $A -eq 1 -a $B -eq 0 -a $C -eq 1 -a $D -eq 1 ] && echo "errors: A and C and D" || { [ $A -eq 1 -a $B -eq 0 -a $C -eq 0 -a $D -eq 1 ] && echo "errors: A and D" || { [ $A -eq 1 -a $B -eq 0 -a $C -eq 1 -a $D -eq 0 ] && echo "errors: A and C" || { [ $A -eq 0 -a $B -eq 1 -a $C -eq 0 -a $D -eq 0 ] && echo "errors: B" || { [ $A -eq 0 -a $B -eq 1 -a $C -eq 1 -a $D -eq 0 ] && echo "errors: B and C" || { [ $A -eq 0 -a $B -eq 1 -a $C -eq 1 -a $D -eq 1 ] && echo "errors: B and C and D" || { [ $A -eq 0 -a $B -eq 1 -a $C -eq 0 -a $D -eq 1 ] && echo "errors: B and D" || { [ $A -eq 0 -a $B -eq 0 -a $C -eq 1 -a $D -eq 0 ] && echo "errors: C" || { [ $A -eq 0 -a $B -eq 0 -a $C -eq 1 -a $D -eq 1 ] && echo "errors: C and D" || { [ $A -eq 0 -a $B -eq 0 -a $C -eq 0 -a $D -eq 1 ] && echo "errors: D" || [highlight #FCE94F]echo "errors: none"[/highlight] }; } } } } } } } } } } } } } }; unset A B C D;done )

Replace this:
echo "errors: none" };
with this:
echo "errors: none";

Hope This Helps, PH.

OOps, forgot to explain:
you had 15 } for only 14 {
