Am running an older bash version and this may be fixed (assuming it is a bug and I'm not confused...:-))
bash version = 3.2.39(20) This works: 1) if [ -n "" -a 2 -gt 1 ] ; then echo one;fi This does not: 2) if [[ -n "" -a 2 -gt 1 ]] ; then echo one;fi Shouldn't 2 work equally well as 1? (original test on "$1": -n "$1" -a "$1" -gt 0 )
