Description Denis.Ryndine 2013-04-05 12:42:52 UTC

BusyBox version
BusyBox v1.20.2 (2013-04-04 13:18:53 UTC) hush - the humble shell

This runs (not) as expected
while [ 3 -lt 3 ] ;  do echo running;  done

But this is infinite loop
while [ 3 -lt 3 ] && true ;  do echo running;  done

Comment 1 Denis.Ryndine 2013-04-05 13:20:20 UTC

[ 3 -lt 3 ]; echo $?
1
[ 3 -lt 3 ] && true; echo $?
1

So then seems broken while?
